[CTPP] Census Bureau release of "Daytime Population" estimates

by Srinivasan

The Census Bureau recently issued "Daytime population" estimates using Census 2000 data (See http://www.census.gov/population/www/socdemo/daytime/daytimepop.html). These estimates include: a. Workers who go to work, no matter where they live, and no matter what time they travel to work. b. Residents of an area who are not workers, including everyone who is below 16, and c. Everyone else who is not a worker, including employed people who did not go to work in the reference period. For each Place (i.e. city) and County, a ratio of total workers to resident workers is calculated. So, places with high in-movements of workers are distinguished from places with high out-movements of workers. For example, Washington, D.C. and Bethesda, Maryland, have high in-movements of workers. The Census Bureau recognizes that this is an elementary measure as it doesn't address travel for all trip purposes, only work-related travel. The estimates do not address: Children going to school. Workers who leave for work late in the day and work in the evening Leaving home for other purposes like shopping, social or recreational trips. Special attractors: universities, hospitals, entertainment centers, regional shopping centers. Absenteeism from work (vacation, illness, etc). It assumes that people who are not workers, including all people under age 16, and all retired people without jobs, do not leave their residence place or county. So, it is going to be a low estimate for some places, and high for others. The level of geographic reporting is all states and counties, and selected places (those with either 2,500 resident workers or total workers). Using CTPP 2000, you can do a similar calculation for any other geography (e.g.: Census Tracts or TAZ or CBD) by: Daytime population in any geography = CTPP Table 1-047 (total population) MINUS first column in CTPP Table 1-001 (total workers living in an the area) PLUS first column in CTPP Table 2-001 (total workers working in the area) Why the CB's Daytime Population Estimates will not be exactly the same as results using CTPP 2000: 1. CTPP 2000 values are rounded (4, and then multiples of 5), while the CB's county and place daytime estimates are not rounded. 2. The CTPP 2000 workplace locations are tabulated after "extended workplace allocation" was completed, which assigns work locations using industry, occupation, travel mode and travel time to workers for whom a workplace location was incomplete or missing. The CB's daytime population estimates do not use the extended allocation results. 3. The CB calculation used the 100 percent count as its total population figure. This may be different than the sample count shown in Table 1-047 of CTPP 2000 Part 1, particularly for places (counties should be the same). For the United States as a whole: About 46 percent of all persons were workers who went to work, so they are assigned to their workplace location. About 23 percent of all persons are under age 16, so they are assigned to their home location. About 28 percent of all persons over age 16 were not in the labor force, so they are assigned to their home location. Of these people NOT in the labor force, about 40 percent are over age 65. About 3 percent of all persons over age 16 were unemployed, so they are assigned to their home location. Just be aware of the limitations of these estimates if you plan to use them! Thank you!

[CTPP] Censu News Brief

by Ed Christopher

CONFERENCE COMMITTEE LIKELY TO CONSIDER CENSUS FUNDING THIS WEEK Plus: More Census Stakeholders Weigh In on Funding Debate; Senate Approves Adding New Question To the ACS A House and Senate conference committee is scheduled to meet tomorrow to iron out differences between two versions of the Fiscal Year 2006 funding bill that covers the Census Bureau, according to Capitol Hill sources. The tentative schedule calls for the U.S. House of Representatives to appoint members to the conference committee today; the U.S. Senate appointed its conferees in September. Conferees would start meeting on November 3 and complete their negotiations in time to file a conference report in each chamber early next week. The House and Senate would then vote separately on the final bill, which cannot be amended, later in the week. If both chambers approve the conference bill, the measure will be sent to the President for his signature or veto. The Appropriations panels involved in the conference are the House Subcommittee on Science, State, Justice, and Commerce and the Senate Subcommittee on Commerce, Justice, and Science. Traditionally, all members of those subcommittees serve as conferees. The House allocated $65 million less for the Census Bureau than President Bush requested for Fiscal Year 2006 (FY06), while the Senate approved $150 million less than the President requested and $17 million less than the Fiscal Year 2005 funding level. (Formated table attached) Potentially complicating the funding picture for the Census Bureau, the House Appropriations Committee is meeting today to revise the amount of money allocated to each of its twelve spending panels at the start of the FY06 budget process last spring. The so-called 302(b) allocations, named after a provision of the 1974 Congressional Budget Act, set spending ceilings for each appropriations account, every fiscal year. Within those ceilings, each appropriations subcommittee must fund the wide range of federal programs under its jurisdiction. A lower allocation for the Science, State, Justice, and Commerce Subcommittee would further squeeze the amount of money available for Census Bureau programs. Secretary of Commerce Carlos Gutierrez wrote to appropriators on October 27, to highlight programs in the Commerce funding bill that are a priority for the department. The secretary asked conferees to allocate no less than the House mark for the Census Bureau, saying that the Senate funding level would eliminate the American Community Survey and require the more costly and less useful Long Form in the 2010 census, at an additional cost of more then $1 billion. The investments Congress has made over the last ten years to modernize the Census and develop the American Community Survey would be lost, Secretary Gutierrez wrote. The Census Bureau is part of the Economics and Statistics Administration within the Department of Commerce. Important census data at risk, stakeholders tell Congress: Stakeholders who rely on census data for planning, program development and evaluation, resource investment decisions, service delivery, and grant applications continued to urge Congress to preserve Census Bureau programs in FY06 (which began October 1st). State and local governments, businesses and industry groups, scientific associations, non-profit and civil rights organizations, in a wave of letters to appropriations panel members, called on legislators to allocate sufficient funds for the American Community Survey (ACS), 2010 census tests, and other demographic surveys and economic data programs. Some highlighted the need for information on populations and communities affected by Hurricanes Katrina and Rita. Louisiana Governor Kathleen Blanco wrote that the ACS was an important federal tool for making prudent investment decisions to help more than one million residents displaced by the hurricanes. Rep. Tom Davis (R-VA), chairman of the Government Reform Committee, and Rep. Michael Turner (R-OH), chairman of the panels Subcommittee on Federalism and the Census, asked Speaker Dennis Hastert to support temporarily expanding the ACS in the regions affected by Hurricane Katrina, to produce detailed data every few months, at an estimated cost of $50 million. If allocations [of federal funds] are made in the absence of timely, detailed, and accurate information, the risk is very high that billions of dollars invested in relief and reconstruction efforts will be ineffective, the congressmen wrote on September 23. The Population Association of America and Associations of Population Centers continued their outreach to Congress, saying in a letter that, Information on occupation, educational attainment, English language proficiency, housing conditions, and many other important topics will help officials create conditions and services needed to support successful community rebuilding in the aftermath of the storms. New York City Mayor Michael Bloomberg said that his city uses ACS data for transportation, housing, education and community development planning, and that without the survey, decision makers in both the public and private sectors will lose a valuable tool for deciphering emerging trends in American life. The U.S. Conference of Mayors wrote that the Senate funding level is not enough to employ the latest innovations and improved counting techniques that will help ensure a more accurate count in the 2010 census. Highlighting the importance of economic data in its second letter to lawmakers, the U.S. Chamber of Commerce called federal statistical agencies highly efficient and motivated organizations that provide a vital service to all sectors of the American economy, especially noting decisions affecting monetary policy, business investment strategies, trade negotiations, and household finances. Individual businesses, including Target Corporation and JC Penney, also sent letters to the Hill, as did the International Council of Shopping Centers. The National Association of Business Economists urged its members to inform Congress about the potential loss of economic data on manufactured products, manufacturers sales and inventories, business hi-tech equipment and software expenditures, and service industry expenses, all funded through the Census Bureaus Salaries and Expenses account. The National Association of Latino Elected and Appointed Officials (NALEO) Educational Fund expressed its concern about the future of the ACS and 2010 census improvements several times, most recently organizing a letter to conferees signed by 13 organizations. The stakeholder groups noted that the Census Bureau had requested a funding increase for the ACS because the survey will entail 12 full months of costly field data collection in 2006, compared to only nine months during 2005, the start-up year. Congress also failed to allocate enough funds in 2005 to include group quarters (e.g. college dorms, military barracks) in the ACS. The letter reminded Congress that most key decisions affecting the design and scope of the 2010 census will be made in the next year. The diverse letter signers included the American Foundation for the Blind, Arab American Institute Foundation, National Association of Counties, American Jewish Committee, National Low Income Housing Coalition, and Consortium of Social Science Associations. Senators Susan Collins (R-ME) and Joseph Lieberman (D-CT) warned conferees that the Senate funding level for the Census Bureau would have dire consequences on the planned improvement for Census 2010, and will lead to the elimination of Census programs that improve government and businesses ability to understand and provide services to communities. The House-passed funding level for census programs, they said, is a small investment that can yield a mighty return, and the American people deserve it. Sens. Collins and Lieberman are the chairman and ranking minority member, respectively, of the Census Bureaus oversight committee. Rep. Carolyn Maloney (D-NY), a member of the Federalism and the Census Subcommittee, sent her House colleagues an editorial by The Washington Post (Down for the Count, Oct. 29, 2005), which urged Congress to accept the House-passed funding level for the Census Bureau. The editorial noted the wide range of stakeholder groups advocating adequate funds for the bureau and concluded that, Less useful data for more money is a shortsighted tradeoff even in this tight budgetary environment. Senate bill would add new question to American Community Survey: While appropriators deliberated 2006 spending levels for the Census Bureau, the Senate adopted an amendment to NASAs reauthorization bill (S. 1281) that would require the bureau to add a question to the ACS on field of degree of college-educated individuals. The data would benefit the National Science Foundation, according to section 153(a) of the bill. The amendment was sponsored by Sen. Kay Bailey Hutchison (R-TX), a member of the Appropriations Subcommittee on Commerce, Justice, and Science and chair of the Science and Space Subcommittee of the Committee on Commerce, Science, and Transportation. It was cosponsored by Sen. Bill Nelson (D-FL). The Senate approved the amendment and bill on September 28; the House version of the NASA reauthorization bill (H.R. 3070) does not include a similar provision related to the ACS. House census staffer leaves Congress for Archives: David McMillen, a lead congressional staff member on census and statistical issues for 14 years, has assumed the new position of External Affairs Liaison at the National Archives. Dr. McMillen was most recently a professional staff member for Rep. Henry Waxman (D-CA), the ranking Democrat on the House Government Reform Committee, which oversees the Census Bureau. He previously worked on the Senate Governmental Affairs Committee in a similar capacity, specializing in a wide range of information policy issues including the Freedom of Information Act, Paperwork Reduction Act, Privacy Act, and data confidentiality. Before coming to Congress, Dr. McMillen was employed by the Census Bureau as a demographer and statistician. In a press release, United States Archivist Allen Weinstein said that Dr. McMillens appointment will help the agency open the doors to dialogue and collaboration with all of the organizations that share interests and relationships with the National Archives. Dr. McMillen will be the full time liaison to stakeholder and customer communities, according to the press statement. [Authors note: David, the entire census stakeholder community is grateful to you for your many years of informed and tireless support of comprehensive and accurate data. We will greatly miss your presence on the Hill, but we know that you will continue to shine in your new position at the National Archives. I wish you the very best on behalf of all of my readers!] Census News Briefs are prepared by Terri Ann Lowenthal, an independent consultant in Washington, DC, with support from The Annie E.

[CTPP] Income variable in future CTPP-like products

by Murakami

Despite the uncertainty of 2006 American Community Survey (ACS) budgeting and implementation, I am raising this query on future CTPP-like products using ACS. For the CTPP2000, there were 2 FLOW (part 3) tables using income: Table 3-5 Income (8 classes + total) Table 3-7 Income (4 classes +total ) by Means of Transportation (4 classes + total) Both of these tables were subject to the Census Bureau's Disclosure Review Board (DRB) requirement of 3 unweighted records, resulting in very high suppression of Origin/Destination pairs at the tract-to-tract (about 70 percent), and TAZ-to-TAZ (often over 80 percent) level. Because the sample size in ACS (even after 5 years of data accumulation) are expected to be perhaps 40-60 percent that of the 2000 decennial census long form sample, it will be even more difficult to reach the threshold of 3 unweighted records for flow tabulation. The CB's DRB has told us that for special tabulations (like the CTPP) "rounding and thresholds are here to stay." Right now, the next level of geography is Place (city or town), which is often too large to be meaningful. We understand that the CB plans to use PUMA as a standard tabulation unit, which could result in a very useful PUMA-to-PUMA flow table for large metropolitan areas, but since PUMAs require 100,000 population, this would be not very useful for smaller metropolitan areas. Here are some alternatives to consider: 1. Using MEDIAN INCOME instead of a distribution. At least one person at the CB thinks that the DRB would be less concerned about this. While this might work for Table 3-5, I don't think it would work for Table 3-7, because there would be a significant probability for one record for a particular mode, e.g. transit, so that the median would be the same as the individual record. 2. Having a SuperTAZ or SuperTract new geographic unit for flow tabulations that include an income variable. How big would a SuperTAZ or SuperTract need to be? I don't know, but my guess is that it would need to be on the order of 4-5 census tracts combined. We know that if we combine only 2 tracts, it will result in approximately 70 percent of suppression, because the unweighted records would be similar in number to the CTPP 2000 tract-to-tract numbers. 3. Omit the income tables from an ACS Flow tabulation, and find another data source. Please let me know what you think, and especially if you have ideas for alternatives. AASHTO SCOP has convened a Census Data Working Group. It is chaired by Jonette Kreideweis of MN DOT. Information about this group was included in the August 2005 CTPP Status Report http://www.fhwa.dot.gov/ctpp/sr0805.htm. AMPO and APTA have now been included as members.

Re: [CTPP] Release of Census 2000 Data Product on Daytime Population

by Bob Paddock

Ed, MY guess is that you are "on the mark" in this regard. That is the approach that I seem to understand from what has been given below. I received two separate inquiries back in July about the "daytime population of downtown Minneapolis". My response was to question their definition of "daytime population" and indicated that the only information I had available to me was the CTPP "Journey-to-Work" tabulations. I made it clear that this did NOT include other trip purposes to downtown, such as shopping, non-home but work-related trips and the like. I suppose that as long as all regions are treated likewise, you could at least get some comparative measurement of this information.

RE: [CTPP] Release of Census 2000 Data Product on Daytime Population

by celia.g.boertlein＠census.gov

Bill, Yes, your points are all well-taken. These are estimates based on the Census 2000 question, "At what location did you work LAST WEEK?" and the directions that included the following -- "If you worked at more than one address or location, give the address or location where you worked most LAST WEEK". As the types of nontraditional work schedules prevail, we all will be challenged to estimate what proportion of the workers are affected by these schedules as well as the proportions that are away from their usual place of work because of vacation, temporary layoff, illness, etc. Not easy tasks. -- Celia G.

As these types of work schedules become more and more prevalent for reducing congestion, personal preferences, etc. it would seem that daytime population estimates would have greater and greater variance.

[CTPP] Release of Census 2000 Data Product on Daytime Population

by Chuck Purvis

This is a message sent to the State Data Center listserv this morning, 10/20/05: FROM THE DESK OF STANLEY J. ROLARK CHIEF, CUSTOMER LIAISON OFFICE October 20, 2005 Subject: Release of Census 2000 Data Product on Daytime Population The Census Bureau will be releasing later today or tomorrow, Census 2000 data on the daytime population. The data are being released for all counties (or co. equivs.) by state in the U.S. There are also subtotal lines for each state and for the U.S. as a whole. There are data for the municipios in Puerto Rico, and a total for Puerto Rico. There are data for places (incorp. and CDPs) in the U.S. by state, but no place data for Puerto Rico. The universe is places with either 2,500 workers living in the place or 2,500 workers working in the place. There will be three separate Excel files. They will be accessible through the Subjects A to Z index, from a link entitled Daytime Population. Table 1 is a summary for places by size. All places > 250,000 are shown, in three size classes. Places less than 250,000 are shown in six size classes, but only the first twenty based on percent increase in daytime pop are shown for each size in Table 1. Table 2 shows all counties by state in the U.S. and Puerto Rico. Table 3 shows places with 2,500 workers living in or working in, by state, for the U.S. (not PR). The data product was developed by the Journey to Work and Migration Statistics Branch in Population Division. The data were developed by combining the Census 2000 data on the residence population with the Census 2000 sample data on place of work. The estimates of daytime population to be released by the Census Bureau only adjust resident populations for travel into or out of an area for work purposes. No adjustment is made for travel to school, shopping, recreation, tourism, health care or for any other trip purpose. The data sources required for making these adjustments are not available on a consistent, nationwide basis. Furthermore, the adjustments to resident population reflected in these "daytime" population estimates do not take the time of day work trips are made into account. The simplifying assumption is made that all workers leave the area in the morning and return to the area in the evening. The release will include data items on the number of workers working in the area, the number of workers living in the area, the estimated daytime population, the number and percent change due to commuting, the number and percent of the workers who lived in the area that also worked in the area, and the employment-residence ratio (workers working in/workers living in). The data are likely to be released with a press release but with no press embargo. While you will be receiving a copy of the press release as part of our normal procedures, I did want to provide you with a "heads up" about this release as you may receive questions and/or have an interest in this release. Census Bureau contact information regarding this release will be included at the top of the press release.

[CTPP] Census News Brief

by Ed Christopher

CENSUS DATA WIDELY USED IN NEW ORLEANS AREA Plus: ACS and Census Long Form Could Be At Risk, Census Bureau Says A wide range of census data was in heavy demand in the days and weeks after Hurricane Katrina ravaged much of New Orleans, a representative of the Greater New Orleans Community Data Center told a gathering of stakeholders at a Washington policy briefing last Friday. Denice Warren, herself an evacuee from New Orleans, participated in a forum sponsored by The Brookings Institution on how proposed funding cuts would affect key Census Bureau programs. The American Community Survey (ACS), key tests for the 2010 census, and several other widely-used economic and demographic surveys could be scaled back or canceled under the Fiscal Year 2006 (FY06) funding level approved last month by the U.S. Senate. Ms. Warren said the GNOCDC tracked visits to its web site (www.gnocdc.org), which features data tables and maps on important neighborhood characteristics, including poverty, educational attainment, transportation, employment, housing, and immigration. For the first half of 2005, the web site received roughly 5,000 hits per month. That number jumped to 40,000 in August and 80,000 in September, suggesting that public officials, relief organizations, and the media relied heavily on data (much of it derived directly or indirectly from the Census Bureau) to assess the consequences of Hurricanes Katrina and Rita and to help plan recovery efforts. The forum also featured remarks by Dr. William OHare, KIDS COUNT Program Coordinator, The Annie E. Casey Foundation; James Eskew, Assistant Director, Cushman & Wakefield Client Solutions, which helps businesses make informed location decisions; and Dr. William Frey, Visiting Fellow, Metropolitan Policy Program, The Brookings Institution. Dr. OHare noted that public and private sector data users have invested a great deal of time and money in preparing to use American Community Survey estimates, and that a once-a-decade model for collecting information ignores how quickly modern society is changing. Dr. Frey also warned that collecting detailed socio-economic data once-a-decade fails to recognize the dynamic nature of 21st century America. Mr. Eskew highlighted how census data are the foundation for analyzing and comparing local economies when businesses are looking to build new headquarters, plants, or stores. The four Brookings forum presentations are available at: http://www.brookings.edu/metro/umi/20051014_censusfundingFY2006.htm (scroll down to the bottom of the gray box). Census funding update: With 2006 funding and the future of the American Community Survey still uncertain, The Washington Post reported last Friday that the Census Bureau is floating the idea of a 2010 census with only a short-form population and race count that would provide the data needed for congressional apportionment and redistricting, even if it stops the ACS after this year (The Washington Post, 10/14/05, The Federal Page). The bureau could consider such a scenario if Congress fails to provide enough money to continue the ACS in 2006 and if money is tight, the Post article said. Census Bureau officials told the newspaper, as well as congressional appropriators, that suspending the ACS and planning for a 2000-style census in 2010 would add $1.3 billion to the estimated $11.3 billion lifecycle cost of the next count. Census Bureau Director C. Louis Kincannon told the Post that a FY06 funding level materially below the House mark of $812.2 million would spell trouble for key agency programs and plans, including the ACS, automated data collection in the 2010 census, and the 2006 Census Field Test in Travis County, Texas, and on the Cheyenne River Sioux Indian Reservation in South Dakota. The Senate allocated $727.4 million for the Census Bureau, $150 million less than President Bush requested and $17 million below the 2005 funding level. The Washington Post article also quotes a spokeswoman for Sen. Richard Shelby (R-AL), Virginia Davis, as saying: Senator Shelby recognizes the important work being done by the Census Bureau, but he believes that we must balance that with the tight budget constraints that Congress is facing. Sen. Shelby chairs the Appropriations Subcommittee on Commerce, Justice, and Science; he did not chair the subcommittee with responsibility for Census Bureau funding in the last Congress. Dan Scandling, a spokesman for Rep. Frank Wolf (R-VA), who chairs the Appropriations Subcommittee on Science, State, Justice, and Commerce, told the Post that House members will push to keep [the Census Bureaus budget] at House levels. (Note: The House and Senate Appropriations Subcommittees with responsibility for funding the Commerce Departments Census Bureau no longer have fully comparable jurisdictions.) Appropriations conferees: The U.S. Senate appointed conferees last month to negotiate a final spending bill that includes the Census Bureau. All members of the Appropriations Subcommittee on Commerce, Justice, and Science are conferees. Please see the March 11, 2005, Census News Brief posted at www.thecensusproject.org for a list of subcommittee members. The House of Representatives has not formally appointed its conferees, but according to tradition, all members of the Subcommittee on Science, State, Justice, and Commerce will likely serve on the conference committee. Please see the February 24 Census News Brief for a list of panel members.
