4. 4 Federal Statistical System Decentralized: Census, BLS, NASS, NCHS, NCES, BJS, etc….. Federal: states also provide data through coordinating arrangements: vital statistics Chief Statistician (Katherine Wallman) resides in OMB and coordinates the system through “forms clearance.” Thus a relatively diverse system.

6. 6 Useful Distinctions… Publicly Collected Data: federal, state or local Privately Collected Data: –Trade Associations –University researchers –Private Businesses, including the “data industry”

7. 7 Questions to consider… Who collected the data? Who tabulated and published it? Why is it published? What level of detail is available: –Geography –Breakdown categories –Time series

17. 17 Counting vs. Estimation Ongoing debate and controversy in the U.S. and elsewhere. Census data are fallible and often fraught with error. Census-taking is a statistical process and is enhanced by the use of the statistician’s full arsenal.

18. 18 Planning Census 2000 Controversies from 1990 affected 2000 planning: cost and quality of data Republicans and Democrats took opposing positions on census methods……. Could the differential undercount of minorities be lessened with a sample survey and dual systems estimation?

19. 19 Planning... Newt Gingrich sued Bill Clinton over sampling The Supreme Court decided (January 1999): –Sampling could not be used for non response follow up –Sampling could be used for the Accuracy and Coverage Evaluation Program

20. 20 The Advertising Campaign Census participation is a “civic” duty Census Director Kenneth Prewitt conducted a highly visible promotional campaign Congress appropriated $167 million for a professional advertising campaign Census website provided daily updates of response rates (March-April 2000)

25. 25 Classification of Race and Ethnicity “Standards for Maintaining, Collecting, and Presenting Federal Data on Race and Ethnicity,” are promulgated by the U.S. Office of Management and Budget (OMB) The new classification of race permits respondents to “select one or more” racial group.

26. 26 Race and Ethnicity, continued Categories for race: –American Indian or Alaska Native –Asian – Black or African American – Native Hawaiian or other Pacific Islander –White –Other (on census) Categories for ethnicity: –Hispanic or Latino – Not Hispanic or Latino
