Source of the Profiles:

These demographic profiles, based on the both the Census 2000 short-form (Summary File 1 data) and long-form (Summary File 3 data), are adapted from the U.S. Census Bureau's release on May 14, 2002 entitled Census 2000 Profiles of General Demographic Characteristics: Illinois.  Each profile includes four tables labeled DP-1 through DP-4 that provide various population, housing, social, and economic characteristics from the 2000 Census.  The DP-1 table was available as part of the Summary File 1 release from last year, and the other three tables are drawn from the Summary File 3 (SF3) data set .  The complete release of all SF3 tables will occur in the summer of 2002.

The Census Bureau's May 14, 2002 release included demographic profiles for the following geographic areas:  the state as a whole, counties, county subdivisions (political townships in Illinois), places, metropolitan areas (state portion only), and congressional districts (106th Congress).  Only the profiles for all counties, political townships, and incorporated places (municipalities) in Northeastern Illinois were extracted and then augmented with user notes and definitions by NIPC staff.

Subject Content:

100-percent data.  The first table of the demographic profile contains the 100-percent data, which are compiled from the questions on the Census 2000 short form questionnaire asked of all people and about every housing unit. Population items include sex, age, race, Hispanic or Latino by race and type, household relationship, household type, and group quarters population. Housing items include occupancy status, vacancy status, and tenure (owner occupied or renter occupied).

Table DP-1 (Profile of General Demographic Characteristics) includes a total of 71 population and 25 housing variables for the total population and population totals for a limited list of race and Hispanic or Latino groups.

Sample data.  The sample data products (Tables DP-2 through DP-4) are based on answers to the questions on the Census 2000 long form questionnaire and were asked of a sample of housing units and persons in group quarters (e.g., college dormitories).  The Census 2000 long form is based on varying sampling rates that were determined by the size of the governmental unit.  This resulted in an overall sampling rate of about 1-in-6.

Population items include ancestry, disability status of the civilian noninstitutionalized population, grandparents as caregivers, income in 1999, poverty status, labor force status, occupation, industry, class of worker, language spoken at home, marital status, migration (residence since 1995), nativity and place of birth, region of birth of the foreign born, citizenship, year of entry, place of work, journey to work, school enrollment and educational attainment, and veteran status.

Housing items include house heating fuel, number of rooms, occupants per room, number of bedrooms, plumbing and kitchen facilities, telephone service, units in structure, utilities, mortgage, taxes, insurance, fuel costs, value of home or monthly rent paid, selected monthly owner costs as a percentage of household income, gross rent as a percentage of household income, vehicles available, year moved into residence, year structure built, and year householder moved into unit.

DP-2 (Profile of Selected Social Characteristics) includes 102 variables of social characteristics.  DP-3 (Profile of Selected Economic Characteristics) includes 95 variables of economic characteristics, while DP-4 (Profile of Selected Housing Characteristics) includes 100 variables of housing characteristics.

The profiles for counties, townships, and municipalities in Northeastern Illinois are available here to view, print, or download.  They are in the Adobe Acrobat Portable Document File (PDF) format.  The Adobe Acrobat Reader needed to open PDF files is available for free from the Adobe web site.

(Important note:  If your Profile PDF file prints out large black pools of ink instead of user notes and tables, please go to http://censtats.census.gov/techdoc/pdfprint.htm for some very easy-to-follow instructions on a "fix.")
