As the U.S. Census Bureau provides population and housing data only for certain geographic areas (see "census-defined" areas), Seattle also uses several "locally-defined" areas which help various neighborhoods understand their particular demographics. These currently include:
- Community Reporting Areas | Overview Map
- Neighborhood Districts | Overview Map New!
- Neighborhood Planning Areas | Overview Map
- Urban Centers and Villages | Overview Map
How Locally-Defined Areas Are Created
To obtain census data for these geographic areas, the City used different combinations of census tracts, block groups and blocks to best approximate the various neighborhoods and sub-areas of the city. Where the locally-defined boundaries split a block group or tract, that block group or tract was included if more than 50 percent of its population lived within the locally-defined area. (See note regarding geographic comparability with 1990.)
For each locally-defined area, the City of Seattle provides various maps and reports.
- Maps - each area and the census geographies that were used to define them.
- Race/Ethnicity Report - report derived from the census 2000 SF1 complete count data on different race categories and Hispanic/Latino ethnicity. Please be aware that total population counts may not match the other reports because the subject reports were derivied from the census 2000 SF3 sample data.
- 10 Subject Reports - present information on age, commuting, disability, education, employment, income, housing, language, poverty, and residency. This information comes from Census 2000 data collected from a sample of Seattle's population and households who answered the long form of the Census 2000 questionnaire (Summary File 3 - SF3). Some tables outlined in the subject reports, as noted by a "PCT" tag, include no data because those data are not available from the Census Bureau for block groups.
- Detailed 58-Page Report - derived from the Census 2000 SF3 sample data, but provides many more detailed tables then the subject reports. (coming in the fall)
(See note regarding data comparability with 1990 and derived measures in the reports.)
