Tabulations

  • Base or detailed tables, for 1-year, 3-year, and 5-year periods, all geographies that meet the relevant population size cutoff—Hundreds of tables that cross-classify two or more characteristics for a wide variety of subjects (for example, employment by sex and age); race and Hispanic-origin iterations for key characteristics; tables providing item imputation rates. For 1-year and 3-year periods, collapsed tables may be provided when categories in a detailed table are suppressed because the estimates do not meet minimum precision criteria.

    Similar to the tabulations in Summary File 3 from the 2000 long-form sample; 5-year period ACS estimates will also include tabulations of journey-to-work items for traffic analysis zones (one or more blocks, block groups, or census tracts) that, in 2000, were produced on a special tabulation basis (known as the Census Transportation Planning Package).

  • Subject tables, for 1-year, 3-year, and 5-year periods, all geographies as above—Over 60 single-topic tables of frequently requested information, with distributions and medians.

    Comparable to the Quick Tables from the 2000 long-form sample but with more detail.

  • Population profiles for selected race, ethnicity, and ancestry groups, for 1-year, 3-year, and 5-year periods, areas with 1 million or more people—Key distributions (availability of 1-year and 3-year profiles depends on the size of the group). New data product for the ACS. Profiles will be produced for most of the groups tabulated in Summary File 4 from the 2000 long-form sample.

  • Data profiles (single year), all geographies with 65,000 or more people—Four profiles of demographic, social, economic, and housing characteristics and one narrative. Comparable to profiles from the 2000 long-form sample with more geographic detail; narrative profile, which covers all four subject areas, is new.

  • Multiyear profiles, all geographies with 65,000 or more people—Four profiles for the current year and four prior years, indicating differences for a specified year from the current year that are statistically significant with 90 percent margin of error. New data product for the ACS; multiyear profiles are available for the 2000–2004 ACS test surveys; the first release of multiyear profiles from the full ACS will be in 2008.

  • Ranking tables and charts, for 1-year periods—86 ranking tables for states that
