Funding for Research on the Socio-Economic Change in Cities

by Chuck Purvis

Please forward the following announcement of research grants to anyone who has performed interesting research on urban issues. Summary: HUD's Office of Policy Development and Research wishes to fund from seven to ten empirical research projects on trends in urban areas, that is, social, economic, demographic, and fiscal change in cities. Research grants of up to $40,000 each would allow HUD to commission a variety of in-depth and high-quality research projects. For example, the release of the Census 2000 long-form data presents an excellent opportunity to inform us on the long-run dynamics of population, housing, income, and transportation in urban areas. Research using other current data sets, such as the County Business Patterns Special Extracts, FBI Crime Statistics, or Building Permits Data found in the State of the Cities Data Systems or concerning other topics such as the fiscal condition of cities, crime, poverty, or economic development would also be encouraged. These research projects would provide HUD with a basic understanding of how cities are changing, what factors are driving change, and the impact of public policy on change. Available Funds: $300,000 from HUD's FY 2002 research and technology appropriation. HUD anticipates funding seven to ten studies on these topics; studies will be funded through cooperative agreements, up to a maximum of $40,000. Eligible Applicants: Academic and not-for-profit institutions located in the U.S., State and local governments, and federally recognized Indian tribes are eligible to apply. For-profit businesses also are eligible; however, they are not allowed to earn a fee. Application Deadline: May 27, 2003. Further Information: see FR-4780-N-01 (Wednesday, March 26, 2003) in the Federal Register (http://www.access.gpo.gov/su_docs/fedreg/a030326c.html).

Definitions of Disability

by Suzanne O'Neill

Between 1990 and 2000 there are large increases in the population of people with disabilities as related to transportation. The questions asked on the long form changed substantially and the data is presented differently. In 1990, the data was presented as people who have either mobility or self-care disabilities (I suppose you chose one or both). In 2000, I believe the question was formatted to ask if people had disabilities that affected their ability to travel outside the home. The data is presented by type of disability including Sensory, Physical, Mental, Self-Care, Go-Outside-Home, and Employment disabilities. I am wondering if anyone knows how much of the increase in the number of people reporting "Go-Outside-Home Disabilities" over the 1990 "Mobility Limitations" is due to the way in which the questions were asked and how much is due to increases in this population? The elderly have a higher incidence of disabilities so as the elderly population increases one would expect an increase in the numbers of people with "Mobility" or "Go-Outside-Home" disabilities. Also, the incidence of certain kinds of disabilities has been increasing in new-borns. In the past I have used formulas to calculate transit demand for the general population or for the population of the elderly and disabled. They are calibrated based on the 1990 definitions. When I use the 2000 numbers, there are some definite problems - the formula for Elderly and Disabled trip demand is higher than the Total trip demand. How might I need to adjust these to account for differences in the definitions? Has anyone worked on adjusting or re-calibrating demand formulas based on the new definitions and actual ridership in communities? Suzanne O'Neill TransitPlus, Inc.

PUMS news

by Chuck Purvis

News from the Census Bureau on the 1-percent PUMS file. From their 4/11/03 Products Update listserv e-mail: "HOT TIP I am eagerly awaiting the Census 2000 microdata. What can you tell me about it? Starting later this month the Census Bureau will begin releasing state files with 1 percent of the microdata records for households that answered a long form (the sample questionnaire). Microdata records show the actual responses made by households -- less any identifying information that would violate the confidentiality of the respondent's answers. These files allow users to create their own tabulations. The files will be available online in ASCII via FTP. Once all states are released, we will release the full 1-percent microdata on a CD-ROM to be sold for $50 by the Customer Services Center. The disc will come with Beyond 20/20 software facilitating the use of the disc. Later in the year the Census Bureau will release a 5-percent microdata file, again on a flow basis online in ASCII via FTP. Once all states are released, we will release both the 1-percent and the 5-percent microdata files on one DVD to be sold by the Customer Services Center. For more details on these files and their geographic identifiers, go to < http://www.census.gov/population/www/cen2000/pums.html>.

Census News Brief (long post)

by ed christopher

Census Bureau Revises Census 2000 Accuracy Estimates; Los Angeles Sues For Data On Outdoor Enumeration Plus: Test Of Voluntary ACS Response Begins; Appropriations Update; New Congressional Committees Overseeing Census The Census Bureau has revised its estimates of undercounts and overcounts in Census 2000, based on further evaluation of the Accuracy and Coverage Evaluation (A.C.E.) survey conducted after the initial census enumeration. The latest findings are dramatically different from earlier calculations of census accuracy, Bureau officials said. They discussed the A.C.E. Revision II estimates the second such revision to the original A.C.E. estimates of census accuracy at a March 12th joint meeting of two National Academy of Sciences census panels. According to A.C.E. Revision II, the 2000 census overcounted the total household population by 0.5 percent, or 1.3 million people, instead of producing a net undercount of 1.18 percent (3 million people), which the Bureau had reported in October 2001. For race and ethnic groups, the new numbers showed a net overcount of 1.13 percent for non-Hispanic Whites and a net undercount of 1.84 percent for non-Hispanic Blacks. There was no statistically significant undercount or overcount for Hispanics, non-Hispanic Asians, Native Hawaiians and Other Pacific Islanders, and American Indians and Alaska Natives on and off reservations. However, the revised estimates also showed a net overcount of children aged 0 9. The additional review of the A.C.E. survey also revealed at least 5.8 million duplicates in the census enumeration, a much higher number than the Bureau found in its first analysis in 2001. Based on the additional review, Census Bureau Director C. Louis Kincannon reaffirmed the agencys prior decision not to statistically adjust the census numbers used as a base for intercensal population estimates. While the new set of A.C.E. estimates represent the most accurate assessment of Census 2000 coverage to date, Kincannon said in a written statement, the Bureau still [has] technical concerns about the limitations of the methodology and the data produced by A.C.E. Revision II. The director cited efforts to account for correlation bias, the effects of synthetic estimation on small geographic areas, and remaining inconsistencies between independent Demographic Analysis estimates and A.C.E. estimates of the coverage of children in the census, as primary reasons for the decision to stick with the raw census counts for all official purposes. The Census Bureau tried for the first time to correct for correlation bias, a statistical concept that refers to the likelihood that certain segments of the population (for example, African American males, aged 18 34) will be missed both in the census enumeration and in the coverage measurement survey. The adjustment in the A.C.E. Revision II estimates was made based on comparisons with national Demographic Analysis estimates, which themselves are produced only for two race categories Black and non-Black by age and sex. Without the adjustment for correlation bias, the Bureau reported, the revised accuracy estimates would have shown a net national overcount of 1.12 percent, instead of 0.49 percent, and a net overcount for non-Hispanic Blacks of 0.53 percent, instead of a net undercount of 1.84 percent. Census Bureau staff said they were uncertain about the choice of scientific models for allocating assumptions about correlation bias among the various groupings (called post strata) that are used to construct adjusted population numbers. They also expressed concern about their inability to determine whether correlation bias exists for children, adult women, and Hispanics. Research has led Bureau experts to assume that correlation bias is highest for adult Black men. Annual or biennial population figures are used to allocate funds for a range of federal programs, including Medicaid, Community Development Block Grants, Social Services Block Grants, and the Training Assistance-Dislocated Worker Program. Intercensal estimates are produced for states, counties, incorporated places, and minor civil divisions; many of these geographic areas have populations below 10,000. Census evaluators said the Bureau cannot be confident of improvements in accuracy [of A.C.E. Revision II adjusted numbers] at the levels of geography for which estimates are produced. The Bureau will post place-level A.C.E. Revision II estimates on its web site in the coming weeks. The data will reflect collection places instead of tabulation places, a distinction that should not affect comparisons with the official, unadjusted place-level data in most areas. Late last fall, under court order in a Freedom of Information Act case, the Census Bureau publicly released block-level A.C.E.-adjusted numbers that reflected the October 2001 revision to the initial set of undercount and overcount estimates. Those data were posted on the Internet by several universities. In response to questions at the National Academy of Sciences meeting, senior Census Bureau officials said the tight schedule for issuing block level counts to the States for redistricting did not leave enough time to adjust those data based on a post-census survey in the 2010 census. The Bureau will measure coverage aggressively and use Demographic Analysis as an independent benchmark in 2010, J. Preston Waite, Associate Director for Decennial Census, told panel members. Using the results of a post enumeration survey to statistically adjust the base for intercensal population estimates was still an open question, Mr. Waite said. The Bureau must first fix problems related to duplication, correlation bias, and errors in synthetic estimates. If those and other concerns are resolved, then the Census Bureau is very likely to adjust intercensal population estimates, Mr. Waite predicted. Mr. Kincannons full statement on the revised accuracy estimates can be found on the Census Bureaus web site at <http://www.census.gov/Press-Release/www/2003/cb03cs02.html>. The technical assessment document can be found at <http://www.census.gov/Press-Release/www/2003/ExecSumm.pdf>. Los Angeles Seeks Detailed Census Data on Homeless Population: The City of Los Angeles has sued the U.S. Department of Commerce (the Census Bureaus parent agency) to gain public release of Census 2000 counts from targeted non-shelter outdoor locations. Last May, the Census Bureau denied the Citys Freedom of Information Act (FOIA) request for separate tabulations of people counted at selected outdoor sites during the service-based enumeration (SBE) March 27 29, 2000. The City filed its lawsuit on November 27, 2002, in federal district court; the Commerce Department filed its response last February. (City of Los Angeles v. U.S. Department of Commerce, U.S. District Court for the Central District of California, Western Division, Case No. 02-9122 WMB) In its lawsuit, Los Angeles noted its extensive efforts to ensure an accurate and reliable count of the homeless population in the City, including identifying more than 7,600 outdoor locations where homeless individuals could be found. It is seeking disaggregated numbers for people counted at outdoor sites, the City said, to help it provide appropriate outreach and other types of assistance to [the Citys] homeless population. In its response to the lawsuit, the Commerce Department countered that the Census Bureau did not produce separate tabulations, below the county level, of people counted at various locations during the three-night SBE. Initial Census Bureau plans called for the separate release of data on people living in emergency and transitional shelters. However, the agency changed course in January 2001 based on concerns about the quality of the data. The population counted in the SBE, including people at pre-identified outdoor locations, instead was combined with Other non-institutional group quarters in standard Census 2000 data products. The Bureau later issued a special report on the emergency and transitional shelter enumeration. The October 2001 report, which included shelter counts for states, metropolitan areas, and large places, emphasized that the numbers should not be construed as a count of people without conventional housing and do not provide a count of the population experiencing homelessness. Some national advocacy groups, including the National Coalition for the Homeless and National Alliance to End Homelessness, supported the Bureaus decision not to release separate data on the homeless, saying efforts to define and count this population would be inaccurate and misleading. Other local service agencies said the data would help them address the needs of people in homeless situations more effectively. In a recent report to Congress, the U.S. General Accounting Office (GAO) reviewed the Census Bureaus decision not to publish separate data from components of the Service-Based Enumeration. Its findings and recommendations are set out in a report entitled, Decennial Census: Methods for Collecting Data on the Homeless and Others Without Conventional Housing Need Refinement, available through GAOs web site at http://www.gao.gov/new.items/d03227.pdf. While acknowledging the problematic nature of counting people without conventional housing, congressional auditors found that the Bureaus failure to clearly and consistently communicate its plans regarding SBE data products led to expectation gaps between the agency and local organizations and governments which helped the Bureau prepare for and implement the census at shelters, soup kitchens, and outdoor locations. A key cause of the Bureaus shifting position on reporting the Service-Based Enumeration data appears to be its lack of clear, documented, and consistently applied guidelines governing the release of data from the 2000 census, the GAO concluded. The absence of such guidelines, the GAO wrote, could undermine public confidence in the accuracy and credibility of Bureau data. For the 2010 census, the GAO recommended thorough testing and evaluation of procedures, under census-like conditions, to enumerate people without conventional housing. It also urged the Bureau to develop clearly documented, transparent, and consistently applied agency-wide guidelines for releasing all census data to the public, which could help the agency be more accountable and consistent in its dealings with data users and stakeholders. American Community Survey update: The Census Bureau is evaluating the effects of voluntary response to the ACS in 31 test sites around the country. All households in the test site samples are receiving questionnaires that indicate response is voluntary, instead of mandatory under the Census Act (title 13, United States Code). (Under preliminary plans to assess voluntary response, respondents in only half of the test sites would have been told their participation was voluntary.) According to the Census Bureau, the ACS voluntary response experiment, which began in March, will continue for at least three months, and possibly longer, depending on funding. Based on lingering concerns over the length and content of the traditional census long form, Congress pressed the Census Bureau to determine how voluntary participation would affect costs and data quality in the ACS. Congress allocated $1 million in the current fiscal year to carry out the evaluation. Chip Walker, a key majority aide on census issues for the House Subcommittee on Technology, Information Policy, Intergovernmental Relations, and the Census, said at a recent association meeting that initial results from the voluntary response test are expected this month. The evaluation should be completed by August, Mr. Walker said, giving Congress time to consider the full results before finalizing the Census Bureaus spending bill for fiscal year 2004. Mr. Walker also told the Council of Professional Associations on Federal Statistics quarterly meeting that the census oversight panel tentatively plans to hold a hearing on the American Community Survey in May. Appropriations update: The process of setting a federal budget and funding levels for federal agencies continues in Congress, with the House and Senate adopting budget resolutions for fiscal year 2004, which begins on October 1. The annual budget resolution is Congress blueprint for federal spending and does not become a law or require the Presidents signature. The House-passed budget (House Concurrent Resolution 95) provides $775 billion for discretionary programs, $9 billion above current levels but below the Presidents budget submission. The Senate version (Senate Concurrent Resolution 23) provides $791 billion in discretionary spending, slightly above the Presidents recommendation. The two chambers are meeting to reconcile differences between their budget plans, which also include differing proposals for tax cuts that were part of the Administrations economic stimulus package. Once the budget plan is finalized, the House and Senate Appropriations Committees will divvy up discretionary funds among the thirteen regular appropriations accounts. The Census Bureau is funded under the Commerce, Justice, State, and Judiciary account and will compete for money with those federal departments and other Commerce Department agencies. Commerce Secretary Donald Evans testified last month before the House and Senate appropriations subcommittees responsible for that account. He told lawmakers that Census Bureau and Bureau of Economic Analysis (BEA) programs help foster economic growth, one of the departments five strategic goals. The Secretary noted that the proposed Census Bureau budget included increased funds to fill gaps in the collection of demographic and economic statistics, to process data from the 2002 Economic Census, and to continue planning for the 2010 census. Additional funds requested for BEA, he said, would help speed up release of key economic statistics and improve the quality and timeliness of the data. Congressional Committees in the 108th Congress: The House and Senate have reorganized their committees and subcommittees for the 108th Congress, with several new faces emerging on panels that fund and oversee the census. In the House, Chairman Frank Wolf (R-VA) and Rep. Jose Serrano (D-NY) continue to hold the top slots on the appropriations Subcommittee on Commerce, Justice, State, and Judiciary, which funds census activities. The Committee on Government Reform, the Census Bureaus authorizing panel, completely reorganized its subcommittees under a new chairman, Rep. Thomas M. Davis, III (R-VA); Rep. Henry Waxman (D-CA) continues as the committees senior Democrat. The newly formed Subcommittee on Technology, Information Policy, Intergovernmental Relations, and the Census is headed by a sophomore legislator, Rep. Adam Putnam (R-FL); Rep. William Lacy Clay, Jr. (D-MO), who served on a previous census oversight panel, returns as the new subcommittees ranking minority member. With Republicans resuming majority status in the Senate, Sen. Judd Gregg (R-NH) is again chairman of the appropriations Commerce subcommittee, while Ernest Fritz Hollings (D-SC) holds the ranking minority position. The Committee on Governmental Affairs has assigned responsibility for census oversight to a newly formed Subcommittee on Financial Management, the Budget, and International Security. Sen. Peter Fitzgerald R-IL), a new member of the full committee, chairs the panel; Sen. Daniel Akaka (D-HI) is the senior Democrat. The chairmen and ranking minority members of full committees usually serve as ex officio members of all of that panels subcommittees of which they are not regular members.
