SOURCE OF DATA FOR THE TABLES IN THIS FILE
U.S. Census Bureau, 2000 Census of Population and Housing, Summary File 3: August 2002.

SUBJECT CONTENT
Summary File 3 (SF 3) contains Census 2000 sample data, which is the information compiled from the questions asked of a sample of all people and housing units. Population items include basic population totals; urban and rural; households and families; marital status; grandparents as caregivers; language and ability to speak English; ancestry; place of birth, citizenship status, and year of entry; migration; place of work; journey to work (commuting); school enrollment and educational attainment; veteran status; disability; employment status; industry, occupation, and class of worker; income; and poverty status. Housing items include basic housing totals; urban and rural; number of rooms; number of bedrooms; year moved into unit; household size and occupants per room; units in structure; year structure built; heating fuel; telephone service; plumbing and kitchen facilities; vehicles available; value of home; monthly rent; and shelter costs.

Altogether, Summary File 3 contains a total of 813 unique tables — 484 population tables with social and economic characteristics and 329 housing tables. They are compiled from a sample of approximately 19 million housing units (about 1 in 6 households) that received the Census 2000 long-form questionnaire.

SUMMARY FILE 3 GEOGRAPHIC COVERAGE
Summary File 3 presents data for the United States, the 50 states, the District of Columbia and Puerto Rico in a hierarchical sequence down to the block group for many tabulations, but only to the census tract levels for others. Summaries are included for other geographic areas such as Zip Code Tabulation Areas (ZCTAs) and Congressional districts (106^th Congress). The Summary File 3 tables covering the different geographic levels in Illinois were released to the public on August 20, 2002.

GEOGRAPHIC COVERAGE FOR THIS FILE
Census tracts are small statistical subdivisions of a county delineated by local participants as part of the Census Bureau's Participant Statistical Areas Program. Census tracts are primarily used to provide a stable set of geographic units for the presentation of census data and to facilitate comparison of data over time. Census tracts generally have between 1500 and 8000 people, with an optimum size of 4000 people. The spatial size of census tracts varies widely depending on the density of population. Physical changes in street patterns caused by highway construction, new development, etc., may require occasional census tract boundary revisions. In addition, census tracts are sometimes split due to population growth, or combined as the result of substantial population decline. While census tracts do not cross county boundaries, they may cross the boundaries of both places and political townships. Census tracts are identified by a 4-digit basic number and may have a 2-digit suffix; for example, 8221.04. The mapping geocode identification for a census tract (used in this file) eliminates the decimal point so that 8221.04 is displayed as 822104.

HOW THE DATA ARE PRESENTED
For this file, the Northeastern Illinois Planning Commission (NIPC) and the Chicago Area Geographic Information Study (CAGIS) have created three spreadsheets presenting selected Summary File 3 population and housing variables for all 1837 census tracts located in the six counties of northeastern Illinois. These spreadsheets are titled as follows:

Table DP-2. Profile of Selected Social Characteristics: 2000
Table DP-3. Profile of Selected Economic Characteristics: 2000
Table DP-4. Profile of Selected Housing Characteristics: 2000

The "Profile of Selected Social Characteristics" table includes a total of 102 variables of social characteristics. The "Profile of Selected Economic Characteristics" table includes 119 variables of economic characteristics. The "Profile of Selected Housing Characteristics" table includes 100 variables of housing characteristics.

In addition to the three tables discussed above, the file now includes all the data items found in "Table DP-1: Profile of General Demographic Characteristics" taken from Summary File 1.
