The 2000 Census: Counting Under Adversity
P-sample household and to find out if misgeocoded E-sample cases were located nearby. Such searching could reduce the variance and bias of the DSE estimates. For efficiency reasons, it was decided in the A.C.E. to target the extended search on selected P-sample and E-sample cases and to conduct it for a subsample of the A.C.E. blocks, instead of conducting searches for every block as in 1990.
Definition of Poststrata
The 448 poststrata in the original A.C.E. design (reduced to 416 for developing the original DSE estimates) were similar to the 357 poststrata that were implemented in the reestimation of the 1990 PES in 1992 (see Section 5-C.4). The 2000 poststrata (see Appendix E, Table E.3) included two additional race/ethnicity domains, one for American Indians and Alaska Natives not living on reservations and another for Native Hawaiian and Other Pacific Islanders (who had been combined with Asians in 1990). The 2000 poststrata also categorized non-Hispanic whites and other races, non-Hispanic blacks, and Hispanics by mail return rate (two categories—high and low—calculated separately for each group by housing tenure). Region was dropped as a stratifier except for people in the non-Hispanic white and other race category who owned their homes. Subsequently for the A.C.E. Revision II reestimation in 2002, extensive changes were made to the E-sample poststratification (see Section 6-B.4).
5–D.2March 2001 Adjustment Decision
In fall 2000, Clinton commerce secretary Norman Mineta delegated authority for the decision on adjustment of the 2000 census to the director of the Census Bureau (65 Federal Register 195, 59713–59716). In the first days of the Bush administration, commerce secretary Donald Evans rescinded the earlier regulation, returning the authority to the secretary (66 Federal Register 37, 11231–11233). The administration also accepted the resignation of director Kenneth Prewitt.
Both versions of the rule on the authority for deciding on adjustment formally established within the Census Bureau an Executive Steering Committee for A.C.E. Policy (ESCAP), which was made up of senior Bureau staff, to recommend to the director whether to
