Proposed Rule Would Delegate Adjustment Decision
To Census Bureau Director
Plus: Census Director Proclaims 2000 "The Good Census";
House Committee Allocates FY01 Funds for Census Bureau;
Telephone Assistance Extended Through June
The U.S. Department of Commerce has issued a proposed rule that would
give the Census Bureau Director sole authority to decide whether to
release statistically corrected census numbers for purposes other than
congressional apportionment. Census Bureau Director Kenneth Prewitt,
with two former census directors at his side, announced the action at a
June 14th press conference in Washington, DC.
Under the proposed rule, the census director would make "the final
determination" on adjusting the census figures. The decision "shall not
be subject to review, reconsideration, or reversal by the Secretary of
Commerce." The notice of the proposed action, published in the Federal
Register, discusses the justification for the delegation of authority.
The decision, the notice says, "turns entirely on operational and
methodological implementation within the expertise of the Bureau of the
Census." Review by the Commerce Secretary would "create the appearance"
that "non-scientific considerations" played a role in the adjustment
decision, according to the background statement. The transfer of
authority would "safeguard both the substance and public credibility of
the decision making process."
The proposed rule would create a committee of "distinguished senior
career [Census Bureau] professionals" to review the operational and
technical aspects of the procedures for measuring census accuracy and
correcting under- and overcounts in the first set of population
numbers. The Executive Steering Committee for A.C.E. Policy (ESCAP)
will then issue a written report recommending whether the director
should release statistically adjusted data. The Census Act requires the
Bureau to transmit block-level population data to the states by April 1,
2001, for use in the redistricting process. The rule sets forth the
twelve members of the steering committee by position; the ESCAP report
would be made public at the same time it is sent to the director.
"A.C.E." is the Accuracy and Coverage Evaluation program, which includes
a quality-check survey of 314,000 households.
At the press conference, former Census Bureau directors Barbara Bryant
and Martha ("Marty") Riche said they support delegating the adjustment
decision to the Bureau chief. Dr. Bryant, who led the agency during the
1990 census for the Bush Administration, noted that significant reform
of the census process began in 1991. Despite the move to paid
advertising and efforts to simplify the questionnaires, it is "not
possible to count everybody" without the use of sampling, she said. Dr.
Riche, appointed by President Clinton to head the Bureau in 1994, said
partnerships with community groups and local officials were a key
improvement for Census 2000. Still, she said, a household-based census
is "simply bound to fall short."
On Monday, Dr. Prewitt sent former Commerce Secretary William Daley a
report prepared by the Bureau's senior staff on the feasibility of using
statistical methods to account for people missed or counted twice in
Census 2000. The report, entitled "Accuracy and Coverage Evaluation:
Statement on the Feasibility of Using Statistical Methods to Improve the
Accuracy of Census 2000," sets forth the rationale for the "preliminary
determination" that the Bureau can produce statistically corrected
census numbers within the legal time frame and that the corrected data
"will be more accurate." In his June 13th response adopting the report's
conclusions, Secretary Daley said, "We owe it to the American people to
use all of the tools at our disposal to make the census as accurate as
possible." The choice, he said, is whether to use statistical methods
to improve census accuracy, or "whether we do nothing." The
differential undercount of racial minorities cannot be eliminated
without using these methods, the Secretary concluded.
The rule making document also notes that in 1980, the Commerce Secretary
formally delegated a similar decision on whether to use sampling methods
to correct the census undercount to the Census Bureau director. That
delegation of authority was rescinded before the 1990 census, when
controversy over an adjustment led to a lawsuit by the City of New York
and dozens of other localities. In 1991, Commerce Secretary Robert
Mosbacher decided not to adjust the 1990 census counts, despite a
recommendation to do so by census director Barbara Bryant.
The rule (in current or modified form) will take effect after a 45-day
public comment period. Comments should be sent to: John H. Thompson,
Associate Director for Decennial Census, Bureau of the Census, Suitland
Federal Center, Suitland and Silver Hill Roads, Building 2, Room 3586,
Suitland, MD 20233. The proposed rule, the Census Bureau's feasibility
statement, and other relevant documents are available on the Bureau's
Web site at <http://www.census.gov/Press-Release/www/presskit.html>.
Census operations update: The Census Bureau has completed 98 percent of
its door-to-door visits to unresponsive households, Dr. Prewitt
announced at the June 14 press conference. The Denver census region,
covering ten states, as well as Puerto Rico, have reached the 100
percent completion rate, the director said. The Los Angeles census
region is on the verge of reaching that milestone, as well.
Census takers are continuing their efforts to count the remaining
908,000 households that did not respond by mail. As of June 13, the
Bureau had counted or declared vacant 99 percent of the housing units
included in the mail out/mail back and follow-up phases of Census 2000.
Census operations continued at a faster pace than in 1990. In the last
census, only 60 percent of the overall workload was finished by June 1,
compared to 82 percent by the same date this year.
Other highlights of Dr. Prewitt's Census 2000 status report were:
* 117 million census forms had been scanned, and the
accuracy rate for scanning was the same both for forms returned by mail
and those completed by an enumerator.
* Census workers completed telephone interviews with
90,000 households in the Accuracy and Coverage Evaluation (A.C.E.)
sample.
At a June 8th press briefing, Dr. Prewitt told reporters there was "no
bad news to report" about Census 2000 operations. He characterized the
nation's 22nd decennial count as "the good census" and cited the
"enthusiasm, commitment, and dedication" of census workers as a primary
reason for the operational success. The director also said an "echo
effect" from the marketing program helped keep Census 2000 operations on
schedule and well ahead of the 1990 pace for similar activities. "We
underestimated," he said, "the lingering effect of the advertising
campaign and partnership program."
The director expanded on his characterization of Census 2000 at the June
14 press conference. A "good census," he said, meets three criteria.
It is "operationally robust and successful; open, transparent, and earns
the public trust; and dedicated to being fully inclusive."
NRFU visits are scheduled to end on July 7. Census workers have started
follow-up telephone calls (called Coverage Edit operations) to
approximately 2.2 million households that listed six or more residents
(questionnaires were designed to collect information for up to six
people, with space provided to list additional residents) or that
reported information for only some of the people listed as residents.
Clean-up operations (called Coverage Improvement Programs), which
include rechecking housing units designated as vacant or nonexistent in
earlier visits, will be conducted on a flow basis from early July into
August. During this operation, census enumerators also will visit
addresses submitted by local governments since last fall as part of the
"New Construction" phase of the Local Update of Census Addresses (LUCA)
program. The Bureau will start in-person interviews with households in
the quality-check A.C.E. survey on June 19, in neighborhoods where NRFU
operations are complete.
Despite his upbeat assessment, Dr. Prewitt noted several problems that
he said the Bureau had moved quickly to alleviate. The Census Bureau
added enumerators, authorized overtime payments, and created narrowly
targeted Public Service Announcements in English and Spanish to help
boost response rates in the "small number" of Local Census Office areas
where completion rates are lagging. The director has visited several
cities in recent weeks, including Chicago, Baltimore, Columbus (OH), and
Milwaukee, to convey the message that, "It's not too late to be
counted."
During last week's Census 2000 briefing, the director also warned that
census workers trying to finish their workload still encounter "real
resistance," some of which he described as "organized." He displayed a
sign taped to the doors of some unresponsive households, bearing the
message, "Census Workers Are Not Welcome Here. Do Not Knock." The
printed sign provides space to list the gender and age of up to six
residents, and concludes by saying, "This is all you need to know and
are entitled to ask. Have a nice day." A logo and Web address for "The
Heartland Institute" (www.heartland.org <http://www.heartland.org>) is
printed at the bottom.
In a written statement issued on June 8, the Institute's president and
CEO, Joseph Bast, said his organization "does not advise anyone to
violate the law," but that the questions asked in the census "[go] far
beyond any reasonable interpretation of the 'Enumeration' authorized by
the Constitution." The statement described the Institute as an
"independent, nonprofit research organization" in Chicago that
addresses issues such as school reform, environmental regulation, and
tax policy. Mr. Bast said "many political leaders, including Texas Gov.
George W. Bush, Sen. Chuck Hagel, and Rep. Tom Coburn have stated
publicly that people should not answer Census questions they believe
invade their privacy." The poster, which Mr. Bast said appeared on the
back of the Institute's monthly newspaper sent to 45,000 people, also
bears a small-print "warning" about penalties for not answering census
questions.
Telephone help lines to remain open longer: The Census Bureau has
decided to keep its toll-free telephone assistance lines (TQA) open
until June 30, about three weeks past the original shut-down date of
June 8. TQA operators will continue to accept census responses over the
phone in the six languages in which questionnaires are printed (English,
Spanish, Chinese, Korean, Tagalog, and Vietnamese) from people who did
not mail back a form and have not been visited by a census taker, or
people who believe they were left off the questionnaire completed for
their residence.
People who provide their answers over the telephone might still receive
a visit from a census enumerator, if the address is included on the list
for nonresponse follow-up. The Census Bureau will rely on local
governments and complete count committees in areas where response is
lagging to promote the continued availability of the telephone response
option.
Census Bureau funding for fiscal year 2001: On June 14, the House
Committee on Appropriations approved the Fiscal Year 2001 Commerce,
Justice, and State, The Judiciary and Related Agencies funding bill.
The panel allocated a total of $670,867,000 for Census Bureau programs,
about $48.3 million less than the Administration had requested. The
Census Bureau is an agency of the Commerce Department.
Aside from Census 2000, Census Bureau programs did not receive requested
funding increases over current year levels. The committee allocated
$392.9 million for the decennial census, just shy of the
Administration's request. In fiscal year 2001 (FY01), which begins
October 1, 2000, the Census Bureau must finish 2000 census operations,
including the Accuracy and Coverage Evaluation program to measure and
adjust for undercounts and overcounts in the initial set of population
numbers. It also must shut down local census offices and data
processing centers, and begin tabulating and publishing data collected
in the census.
The bill specifies how decennial census funds should be spent, listing
nine broad categories such as field data collection, marketing, data
processing, and testing and evaluation. The Census 2000 appropriation
includes $3.5 million for the eight-member Census Monitoring Board.
The panel allocated $20 million to continue development of the American
Community Survey (ACS), the same amount appropriated for the current
year and $5 million below the President's request. The ACS would
collect demographic and socio-economic data from a rolling sample of
households throughout the decade, with 3 million housing units surveyed
each year. The survey is designed to replace the traditional census
'long form' in 2010 and beyond. The Census Bureau is testing the ACS in
31 sites around the country.
Funding for the decennial census and the ACS is part of the Periodic
Censuses and Programs ("Periodics") account, one of two main funding
categories for the Census Bureau. The Periodics account covers
activities that support census operations, such as mapping, as well as
other mandated censuses of business establishments and local
governments. The House committee allocated a total of $530,867,000 for
the Periodics account, about $14.5 million below the request. The
Census Bureau's second main funding category is Salaries and Expenses
("S&E), which covers ongoing surveys (such as the Current Population
Survey) to collect important demographic, economic, and social
statistics. The committee allocated $140 million for the S&E account,
the same amount appropriated in fiscal year 2000 and $33.8 million below
the Administration's request.
The full House may take up the Commerce spending bill before the July
4th recess starts on June 30. The bill is one of thirteen regular
appropriations bills that fund activities of the federal government.

Sampling Controversy Resurfaces in Congress As Census Director Stands By
Plan to Adjust Counts
Plus: New Jersey Assembly Approves Anti-Sampling Bill;
Legislation Introduced for Count of Overseas Americans; and more.
The controversy over the use of statistical sampling to adjust the
initial census counts reemerged at a congressional hearing last month,
as the Census Bureau began its quality check survey to measure
undercounts and overcounts in Census 2000.
At a hearing of the House Subcommittee on the Census on May 19, Census
Bureau Director Kenneth Prewitt described the agency's plans for the
Accuracy and Coverage Evaluation survey (A.C.E.) of 314,000 housing
units nationwide. Telephone interviews with households in the A.C.E.
sample that had returned a completed census form by mail began in late
April. By May 19, the Bureau had completed 60,000 interviews by phone,
more than its projected 10 percent completion rate for that point in the
process. Census takers will start in-person interviews with A.C.E.
households on June 19 in areas where census takers have finished all
non-response follow-up visits.
Subcommittee Chairman Dan Miller (R-FL) reiterated his long-standing
opposition to the Census Bureau's plan to produce adjusted population
numbers based on the A.C.E. results for purposes other than
congressional apportionment. "[T]here is no guarantee that this plan is
even viable," the chairman said. The Supreme Court ruled 5 to 4 in
January 1999 that federal law prohibits sampling to compile the state
population totals used to allocate the 435 seats in the U.S. House of
Representatives among the 50 states. However, the Census Bureau plans
to transmit adjusted census figures to the states early next year for
use in the redistricting process. A provision of the Bureau's fiscal
year 1998 funding bill also requires the agency to make available census
counts down to the block level that are not adjusted based on the
quality-check survey.
Rep. Carolyn Maloney (D-NY), the panel's senior Democratic member, said
the 2000 census "may well be the best, fairest and most accurate census
ever," not only because of operational successes so far but because "it
incorporates modern scientific methods into its design." The 1990
census, she noted, had a 10 percent error rate, including who are
missed, counted twice, or counted in the wrong location. "The closer
the Census Bureau has gotten to developing a way to fix those errors,
the harder the opponents of a modern census have worked to stop them,"
Rep. Maloney said, referring to the disproportionate undercount of
racial minorities and the poor in urban and rural communities.
Rep. Miller said Republicans question the constitutionality, legality,
and feasibility of a census plan that incorporates sampling and
statistical estimation techniques. He called the decision to issue two
sets of census counts "a political move, clearly against the best
interest of the Nation" by the Clinton/Gore Administration. Pointing to
last year's Supreme Court decision, he cautioned that supporters of the
plan "have yet to win a court case." "Census estimation," the chairman
said, "is not a system that lends itself to trust and integrity."
Rep. Miller described statistical estimation as existing "only in a
virtual world," where people are added to or subtracted from the counts
without verification. This means, he said, that some people who have
filled out and returned a census form "will be counted as less than a
whole person." Rep. Miller also criticized an element of the Bureau's
statistical methodology that he said assumes people of the same race or
ethnicity "act alike and have the same tendencies," by assigning them to
one of nearly 450 demographic groupings (called 'post-strata') for the
purpose of measuring the under- and overcount. The chairman asked the
director for "assurances... that [the adjusted] numbers will be fully
scrutinized by the Bureau and the scientific community, at large, prior
to their release for public use."
Countering the chairman's criticism of the sampling methodology, Dr.
Prewitt said the A.C.E. survey was no more difficult than other large
Census 2000 operations. He called the census "an estimation of the
truth" and said its accuracy should be measured by how close the results
are to the nation's true population. The director noted that census
data are "unstable" for very small areas (such as census blocks)
regardless of whether the figures are adjusted using statistical methods
or not. Adjusted census numbers are "unquestionably" more accurate at
the block level, Dr. Prewitt said in response to a question from Rep.
Miller, than numbers produced from direct counting methods alone. He
also defended the use of demographic 'post-strata' to estimate under-
and overcounts, saying the groupings were based on scientific knowledge
about people with similar probabilities of being missed or
double-counted in the census. A panel of experts convened by the
National Academy of Sciences (the Panel to Review the 2000 Census,
chaired by former Bureau of Labor Statistics Commissioner Janet L.
Norwood) is independently reviewing the A.C.E. statistical methods and
operations.
Dr. Prewitt emphasized that while the Bureau has decided to conduct the
A.C.E. according to a technically sound design, it cannot determine in
advance whether the direct count or the statistically adjusted numbers
are more accurate. "If the Census Bureau does not have confidence in
the A.C.E. results, we will not use it," the director told subcommittee
members. The Census Bureau director, not the Secretary of Commerce, he
said, should make the adjustment decision.
The director also vigorously challenged the assertion that statistical
estimation could invite tampering with the numbers to achieve partisan
advantage. He said the Census Bureau is "not competent" to design and
implement an estimation plan that produces a partisan outcome. "Where
is the evidence?" he asked, that the Bureau has a partisan agenda. Dr.
Prewitt said it is "inconceivable" that the Census Bureau would know how
statistical adjustments would affect the drawing of political district
lines by 50 state legislatures.
Other legislative news: Rep. Carolyn Maloney introduced legislation to
provide funds for the Census Bureau to begin planning a census of
American citizens living abroad in 2003. H.R. 4568 would authorize $5
million for planning a Census of Americans Abroad. Rep. Maloney
introduced a bill (H.R. 3649) last year to require an interim count of
Americans overseas in 2003 and planning to include this population in
the 2010 census. Senator Jay Rockefeller (D-WV) sponsored a similar
bill (S. 1715) in 1999, which was referred to the Senate Committee on
Governmental Affairs.
Census 2000 will include active members of the U.S. armed forces,
civilian government employees, and their dependents, who are stationed
or living overseas on Census Day (April 1, 2000), in the state
population totals transmitted to the President for the purpose of
congressional apportionment. These personnel and their family members
are counted at their 'home of record,' the state in which they lived at
the start of the their military or federal service.
In a letter to Reps. Harold Rogers (R-KY) and Jose Serrano (D-NY),
chairman and ranking minority member, respectively, of the House
Appropriations Subcommittee on Commerce, Justice, State and The
Judiciary, Rep. Maloney said the estimated three to six million American
citizens living abroad "make enormous contributions to our economy" and
"vote, pay taxes, and enjoy the same constitutional protections" as
other Americans. She urged the subcommittee to include funds for
planning an interim count in the Census Bureau's fiscal year 2001
appropriations bill.
Rep. Lee Terry (R-NE) introduced a bill last month (H.R. 4458) that
would limit the questions asked in future censuses to those included on
the Census 2000 short form. The measure was referred to the House
Committee on Government Reform.
Update on Census 2000 operations: The Census Bureau announced last week
that it has counted, either by mail or through a personal visit, about
92 percent of the nation's 118 million housing units. Director Ken
Prewitt said gathering information from the remaining eight percent of
American households posed the greatest challenge for the approximately
450,000 census enumerators working to complete 'nonresponse follow-up'
operations by July 7.
State legislative activities update: The New Jersey State Assembly
yesterday approved a bill to require the use of unadjusted census
numbers for redistricting purposes. The measure passed the
Republican-controlled chamber on a party line vote of 42-34. On May 22,
the State Government Committee approved A. 1682, sponsored by
Assemblyman Michael Carroll (R), by a 3 - 2 vote along party lines.
Assembly Speaker Jack Collins (R) initially scheduled a vote on the
measure for May 25, but agreed to postpone action temporarily after
Minority Leader Joseph Dorio Jr. (D) said legislators and the public
needed more time to consider the bill's consequences. Last week,
however, the Speaker announced that the Assembly would take up the bill
on June 5. The State Senate has not yet considered the measure.

I am interested in collecting together as many recent household travel surveys from around the U.S. as possible, to use in comparative research and also to assist in a NCHRP project on standardization of household travel surveys. If any members of the list have a recent (not more than ten years old) data set that they are willing to share, please let me know how I can obtain a copy . In obtaining copies, it would be most useful if I can obtain the following:
1. A copy of the survey instrument(s)
2. A copy of the data files, preferably in SPSS with variable names and variable labels, or in a data base or other format
3. A copy of any final report or other documentation that describes how the data were collected, what sampling scheme was used, and what, if any, data clean up and manipulation has been done.
If data have been geocoded, it would be most helpful if network times and/or distances were included on any trip files. I do not need address information from the raw data, although TAZs, zipcodes, or other broad geographic locators would be helpful.
Thanks.

Sampling Controversy Resurfaces in Congress As Census Director Stands By
Plan to Adjust Counts
Plus: New Jersey Assembly Approves Anti-Sampling Bill;
Legislation Introduced for Count of Overseas Americans; and more.
The controversy over the use of statistical sampling to adjust the
initial census counts reemerged at a congressional hearing last month,
as the Census Bureau began its quality check survey to measure
undercounts and overcounts in Census 2000.
At a hearing of the House Subcommittee on the Census on May 19, Census
Bureau Director Kenneth Prewitt described the agency's plans for the
Accuracy and Coverage Evaluation survey (A.C.E.) of 314,000 housing
units nationwide. Telephone interviews with households in the A.C.E.
sample that had returned a completed census form by mail began in late
April. By May 19, the Bureau had completed 60,000 interviews by phone,
more than its projected 10 percent completion rate for that point in the
process. Census takers will start in-person interviews with A.C.E.
households on June 19 in areas where census takers have finished all
non-response follow-up visits.
Subcommittee Chairman Dan Miller (R-FL) reiterated his long-standing
opposition to the Census Bureau's plan to produce adjusted population
numbers based on the A.C.E. results for purposes other than
congressional apportionment. "[T]here is no guarantee that this plan is
even viable," the chairman said. The Supreme Court ruled 5 to 4 in
January 1999 that federal law prohibits sampling to compile the state
population totals used to allocate the 435 seats in the U.S. House of
Representatives among the 50 states. However, the Census Bureau plans
to transmit adjusted census figures to the states early next year for
use in the redistricting process. A provision of the Bureau's fiscal
year 1998 funding bill also requires the agency to make available census
counts down to the block level that are not adjusted based on the
quality-check survey.
Rep. Carolyn Maloney (D-NY), the panel's senior Democratic member, said
the 2000 census "may well be the best, fairest and most accurate census
ever," not only because of operational successes so far but because "it
incorporates modern scientific methods into its design." The 1990
census, she noted, had a 10 percent error rate, including who are
missed, counted twice, or counted in the wrong location. "The closer
the Census Bureau has gotten to developing a way to fix those errors,
the harder the opponents of a modern census have worked to stop them,"
Rep. Maloney said, referring to the disproportionate undercount of
racial minorities and the poor in urban and rural communities.
Rep. Miller said Republicans question the constitutionality, legality,
and feasibility of a census plan that incorporates sampling and
statistical estimation techniques. He called the decision to issue two
sets of census counts "a political move, clearly against the best
interest of the Nation" by the Clinton/Gore Administration. Pointing to
last year's Supreme Court decision, he cautioned that supporters of the
plan "have yet to win a court case." "Census estimation," the chairman
said, "is not a system that lends itself to trust and integrity."
Rep. Miller described statistical estimation as existing "only in a
virtual world," where people are added to or subtracted from the counts
without verification. This means, he said, that some people who have
filled out and returned a census form "will be counted as less than a
whole person." Rep. Miller also criticized an element of the Bureau's
statistical methodology that he said assumes people of the same race or
ethnicity "act alike and have the same tendencies," by assigning them to
one of nearly 450 demographic groupings (called 'post-strata') for the
purpose of measuring the under- and overcount. The chairman asked the
director for "assurances... that [the adjusted] numbers will be fully
scrutinized by the Bureau and the scientific community, at large, prior
to their release for public use."
Countering the chairman's criticism of the sampling methodology, Dr.
Prewitt said the A.C.E. survey was no more difficult than other large
Census 2000 operations. He called the census "an estimation of the
truth" and said its accuracy should be measured by how close the results
are to the nation's true population. The director noted that census
data are "unstable" for very small areas (such as census blocks)
regardless of whether the figures are adjusted using statistical methods
or not. Adjusted census numbers are "unquestionably" more accurate at
the block level, Dr. Prewitt said in response to a question from Rep.
Miller, than numbers produced from direct counting methods alone. He
also defended the use of demographic 'post-strata' to estimate under-
and overcounts, saying the groupings were based on scientific knowledge
about people with similar probabilities of being missed or
double-counted in the census. A panel of experts convened by the
National Academy of Sciences (the Panel to Review the 2000 Census,
chaired by former Bureau of Labor Statistics Commissioner Janet L.
Norwood) is independently reviewing the A.C.E. statistical methods and
operations.
Dr. Prewitt emphasized that while the Bureau has decided to conduct the
A.C.E. according to a technically sound design, it cannot determine in
advance whether the direct count or the statistically adjusted numbers
are more accurate. "If the Census Bureau does not have confidence in
the A.C.E. results, we will not use it," the director told subcommittee
members. The Census Bureau director, not the Secretary of Commerce, he
said, should make the adjustment decision.
The director also vigorously challenged the assertion that statistical
estimation could invite tampering with the numbers to achieve partisan
advantage. He said the Census Bureau is "not competent" to design and
implement an estimation plan that produces a partisan outcome. "Where
is the evidence?" he asked, that the Bureau has a partisan agenda. Dr.
Prewitt said it is "inconceivable" that the Census Bureau would know how
statistical adjustments would affect the drawing of political district
lines by 50 state legislatures.
Other legislative news: Rep. Carolyn Maloney introduced legislation to
provide funds for the Census Bureau to begin planning a census of
American citizens living abroad in 2003. H.R. 4568 would authorize $5
million for planning a Census of Americans Abroad. Rep. Maloney
introduced a bill (H.R. 3649) last year to require an interim count of
Americans overseas in 2003 and planning to include this population in
the 2010 census. Senator Jay Rockefeller (D-WV) sponsored a similar
bill (S. 1715) in 1999, which was referred to the Senate Committee on
Governmental Affairs.
Census 2000 will include active members of the U.S. armed forces,
civilian government employees, and their dependents, who are stationed
or living overseas on Census Day (April 1, 2000), in the state
population totals transmitted to the President for the purpose of
congressional apportionment. These personnel and their family members
are counted at their 'home of record,' the state in which they lived at
the start of the their military or federal service.
In a letter to Reps. Harold Rogers (R-KY) and Jose Serrano (D-NY),
chairman and ranking minority member, respectively, of the House
Appropriations Subcommittee on Commerce, Justice, State and The
Judiciary, Rep. Maloney said the estimated three to six million American
citizens living abroad "make enormous contributions to our economy" and
"vote, pay taxes, and enjoy the same constitutional protections" as
other Americans. She urged the subcommittee to include funds for
planning an interim count in the Census Bureau's fiscal year 2001
appropriations bill.
Rep. Lee Terry (R-NE) introduced a bill last month (H.R. 4458) that
would limit the questions asked in future censuses to those included on
the Census 2000 short form. The measure was referred to the House
Committee on Government Reform.
Update on Census 2000 operations: The Census Bureau announced last week
that it has counted, either by mail or through a personal visit, about
92 percent of the nation's 118 million housing units. Director Ken
Prewitt said gathering information from the remaining eight percent of
American households posed the greatest challenge for the approximately
450,000 census enumerators working to complete 'nonresponse follow-up'
operations by July 7.
State legislative activities update: The New Jersey State Assembly
yesterday approved a bill to require the use of unadjusted census
numbers for redistricting purposes. The measure passed the
Republican-controlled chamber on a party line vote of 42-34. On May 22,
the State Government Committee approved A. 1682, sponsored by
Assemblyman Michael Carroll (R), by a 3 - 2 vote along party lines.
Assembly Speaker Jack Collins (R) initially scheduled a vote on the
measure for May 25, but agreed to postpone action temporarily after
Minority Leader Joseph Dorio Jr. (D) said legislators and the public
needed more time to consider the bill's consequences. Last week,
however, the Speaker announced that the Assembly would take up the bill
on June 5. The State Senate has not yet considered the measure.
