RE: [CTPP] Calculating Poverty Rate for all persons at residence

by Murakami

Dear Scott-- Poverty has already been calculated and in included on several CTPP tables. For PERSONS, at the RESIDENCE geography, CTPP2000 includes Table 1-059 Poverty status by Disability Status by Minority Status by Age. The universe is off "persons age 5 and over for whom poverty status has been determined." "Poverty" is a derived variable based on household size, income, and # of children under age 18, and age (65+ or not). http://www.census.gov/hhes/poverty/povdef.html If you want to define poverty differently than the CB has done, you would have to use the Census PUMS (microdata) file, and be limited to PUMA geography.

[CTPP] RE: TAZs and the 2010 Census

by Murakami

I received this email from Bob Paddock today, and thought that a reply to the listserv might be useful... -----Original Message----- From: Bob Paddock [mailto:bob.paddock(a)metc.state.mn.us] Sent: Thursday, April 07, 2005 12:14 PM To: Murakami, Elaine Subject: TAZs and the 2010 Census Elaine, If my question should be addressed to someone other than yourself, please let me know. I have been discussing the future of our agency's TAZ system with the person responsible for our travel demand modeling. Collectively we have wondered just how the TAZ system will be utilized for the 2010 Census and ACS survey data. Since we defined our TAZs in the past based on Census block aggregations, will such efforts be needed for the year 2010? If so, how will all of this work with the ACS? Any thoughts on this? BOB ------------From Elaine------ For purposes of this reply, I will assume that there will be a CTPP-like product from a 5-year accumulation of ACS data. 1. Census Bureau Geography Division is already planning to reserve two TAZ fields for TIGER for 2010 Census. Conceptually, these could be considered as a small "urban" TAZ, and a larger TAZ for statewide planning purposes. However.... 2. The sample sizes from the ACS are much smaller than for decennial census due to 2 main reasons: a. The sample size of 2.5 % per year * 5 years = 12.5% is less than the 16.6% (1:6 h.u. sampling rate) for the decennial census Long Form. (Original design of ACS was 3% per year, so that 3% * 5 years = 15% which is much closer to the 16.6% for LF) b. The ACS non-response follow-up is a sample of 1 in 3 (generally speaking), but higher in areas with low mail-back returns. c. Thus, in the ACS test areas, the actual number of unweighted survey records is 50-60% that of the Long Form. This smaller sample size means tabulations for small geographic units is highly variable and much less reliable, and may be subject to data suppression to protect individual confidentialy. This has implications for any TAZ-based tabulation, and has severe implications for any FLOW tabulation. Under the assumption that the CB retains the requirement of 3 unweighted records for FLOW tabulation (same as imposed on the CTPP 2000), we expect that about 40-50% of tract-to-tract flows would be suppressed. 3. What might be some alternatives? Would people want to define TAZs, based on census blocks, that are closer in size to a census tract? Would census tracts be sufficient as is? Would different TAZs be needed: one for Residence only and Workplace only tabulations, and ANOTHER larger TAZ for FLOW tabulation? Assuming that State DOTs and MPO still want to define TAZs, it would be safe to assume that we would use a GIS-based product similar to TAZ-UP for the CTPP 2000. One outcome may be that the TAZs in your MPO model are likely to be SMALLER than any geographic area tabulation you get from the ACS. You will have to figure out a way to distribute ACS results to your model's TAZs. 4. CB has a project called the LEHD http://lehd.dsd.census.gov/led/ They have been doing some exploration on generating small area home-to-work flows from this, but although this has characteristics like age, sex, earnings, it doesn't have mode to work, travel time, departure time. Also, multi-site businesses, government employment, and other issues on the workplace geography are still being researched. My personal opinion is that there are probably issues on the residence geography as well, e.g. particularly areas with "transient" populations such as students, snowbirds, and migrant laborers. 5. And, of course, we haven't even discussed the quality of the workplace geocoding, so there are plenty of things beyond TAZ definition that need to be addressed regarding a CTPP from ACS. If you haven't planned yet to come to the TRB Census conference (May 11-13), now is the time to sign up! http://www.trb.org/conferences/censusdata/ Elaine Murakami FHWA Office of Planning 206-220-4460 in Seattle

[CTPP] FYI: 2010 Census Advisory Committee

by Murakami

The Census Bureau issued a Federal Register notice on March 18, with responses due on April 8. http://www.census.gov/cac/www/fr-05-5392.html The Census Bureau is requesting nominations for members of this committee which will cover the topics of both the 2010 decennial census and the American Community Survey. The CB FR notice includes the language that the planned committee size is 20 members (as opposed to 40 members which was the size of the Census 2000 Advisory Committee). Dave Clawson, representing AASHTO, was a member of the Census 2000 Advisory Committee. At a recent CTPP Working Group meeting, Dave said that AASHTO would like to continue to participate to represent transportation interests, and they are now working on a self-nomination letter. If you would like to submit materials to accompany the letter, please email him at davidc(a)aashto.org

[CTPP] Census News Brief are back--enjoy

by Ed Christopher

CENSUS NEWS BRIEF--February 11, 2005 President Sends FY06 Budget to Congress Plus: House Creates New Census Oversight Panel; New Commerce Secretary Confirmed President Bush sent his detailed Fiscal Year 2006 budget proposal to Congress on February 7, setting in motion the process for funding federal programs starting October 1, 2005. The budget seeks $877.4 million for the Census Bureau, roughly an 18 percent increase over this years funding level of $744.8 million. Last year, the President requested a 30 percent increase for the Census Bureau, but Congress scaled back the appropriation by $84 million. In a statement on the Presidents budget, Commerce Secretary Carlos Gutierrez said the increase requested by the Administration will support initiatives that will significantly improve the breadth and quality of the information it collects and provides to the country. Among these initiatives is the administrating (sic) of the American Community Survey, modernizing the geographic database information, and developing and testing plans for the Decennial Census based on only a short form. The Administration requested $466.5 million to continue planning the 2010 census, an increase of $74 million (about 19 percent) over the FY05 appropriation of $392.6 million. The Census Bureau would continue reengineering the census to collect basic demographic data needed to fulfill constitutional and legal mandates only, implementing the American Community Survey (ACS) to replace the traditional census long form, and updating its geographic database (Master Address File and TIGER digital mapping system) and aligning map features with Global Positioning System coordinates. In an overview of its budget request, the Commerce Department noted that the 2010 census program will focus on reducing operational risk, improving accuracy, providing more relevant data, and containing cost. In FY06, the Census Bureau will conduct a major field test in Travis County, Texas, and on the Cheyenne Indian Reservation in South Dakota. Preliminary plans for the 2006 field test include testing (1) procedures to improve census coverage (such as large household follow-up, use of administrative records, imputation, and residence rule clarifications); (2) methods for coverage measurement; (3) automated field data collection using hand-held computers; (4) delivery of questionnaires in English and Spanish; (5) mailing replacement questionnaires to unresponsive households; and (6) improved methods to count group quarters (such as college dorms) and people without a usual home. The Presidents FY06 budget does not specify the amount of 2010 census funds to be used for the ACS; however, other Census Bureau documents indicate a proposed appropriation of roughly $170 million for the survey. The Administration asked for $165 million to launch the ACS nationwide in 2005, including $10 million for one-time start-up costs; it received $146 million (reduced to $144 million after a government-wide recission). The American Community Survey will continue nationwide in FY06, with the first estimates for places of 65,000 or greater population released in the summer of 2006. The Census Bureau expects to add group quarters to the ACS in 2006; Congress declined to fund that component of the survey in 2005. The Administration is seeking $80 million for the MAF/TIGER Enhancements Program, slightly less than the program received this year. The budget calls for correcting geographic locations in an additional 700 counties as part of the multi-year effort to improve TIGER accuracy. Funding for the decennial census 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 related to the census, intercensal population estimates, and other cyclical programs such as the quinquennial (thats every five years, folks!) Economic Census and Census of Governments. The Presidents budget seeks $657.4 million for Periodics in FY06, an increase of $109 million over FY05, including $10.4 million for annual demographic estimates (an increase of $1.2 million over FY05). The budget proposes $220 million for Salaries and Expenses (S & E), $24 million more than this years appropriation of $196 million, but the same amount requested for Fiscal Year 2005. The S & E account covers ongoing surveys (such as the Survey of Income and Program Participation) to collect important demographic, economic, and social data. New Commerce Secretary takes office: Carlos M. Gutierrez was sworn in this week as the 35th Secretary of Commerce. The U.S. Census Bureau is part of the Commerce Departments Economic and Statistics Administration. Born in Havana, Cuba, Secretary Gutierrez is the former chairman of the board and chief executive officer of the Kellogg Company. New House panel to oversee census: The House Committee on Government Reform has created a new Subcommittee on Federalism and the Census to oversee activities of the Census Bureau in the 109th Congress. The jurisdiction of the newly-organized panel includes population and demography generally, including the Census, and the Bureau of Economic Analysis, as well as unfunded mandates, grant management reform, brownfields clean-up and redevelopment, and oversight of housing and urban development. Second-term Representative Michael R. Turner (R-OH-3rd) will chair the subcommittee. Chairman Turner is a former mayor of Dayton and a lawyer by profession. According to the congressmans biography, his wife, Lori Turner, is a professional marketer and is the sole proprietor of Dayton-based Turner Marketing. Rep. Wm. Lacy Clay (D-MO-1st), from St. Louis, is the ranking minority member on the subcommittee; he held that position on the previous subcommittee with jurisdiction over the census. The next Census News Brief will provide complete information on membership of the House and Senate committees responsible for overseeing activities of and appropriating funds for the Census Bureau.

[CTPP] Census Bureau news at The Onion

by Chuck Purvis

This came out in today's (2/9/2005) edition of The Onion, America's Finest News Source. Happy Lunar New Year to All. http://www.theonion.com/ ******************************************************************************************************************************************************************************* Census Bureau: 9,000 To 15,000 People Work At Census Bureau WASHINGTON, DC*According to 2004 figures released by the U.S. Census Bureau, between 9,000 and 15,000 people work at the Census Bureau. "It is difficult to obtain an accurate figure on Census Bureau employees, because workers frequently move from department to department," U.S. Census director Charles Kincannon said. "Also, many supervisors failed to return the mail-in forms that asked them to list how many employees they have." Kincannon warned all census-bureau employees to take the census-bureau census more seriously, under penalty of law. *********************************************************************************************************************************************************************************
