## Background

- The Census 2000 Supplementary Survey (C2SS) was an operational test for collecting long form-type data simultaneously but separately from the census.
- Largest household survey ever conducted by the Census Bureau, other than the census long form.

## Survey Methodology

- 700,000 household survey conducted in 1,203 counties nationwide.
- Data collected using the American Community Survey (ACS) methodology and questionnaire.
- Data gathered throughout year.
- Mailout/mailback;
- Computer Assisted Telephone Interviews (CATI); and
- Computer Assisted Personal Interviews (CAPI).
- Over 96 percent weighted response rate.

## Data Products

- Release of C2SS substate results includes 107 core tables.
- Narrative and tabular profiles.
- Demographic, economic, social and housing characteristics for the country, 50 states, almost all cities and counties of 250,000 or more, and almost half of the congressional districts.

## Using C2SS Data

- Comparisons among substate data from the C2SS.
- Future comparisons to 2001 and 2002 Supplementary Surveys, as well as the  American Community Survey.

## C2SS is a preliminary look at data similar to those that will be available from ACS, but with a much smaller sample size.
Some comparisons to the 1990 long form can be made at national and state levels.
Comparisons with 1990 should not be made for substate areas because the impact of methodological differences is magnified in the local data.

## Group Quarters population included in 1990 and 2000 census data, but not in C2SS.

- Comparability: General

## Expected differences with Census 2000 because of differences in residency rules.
Census 2000 uses usual residence; C2SS collects data wherever respondents are found, provided they live there at least 2 months.
Intend to study differences to understand in complete detail.

## Issues regarding collection of race and Hispanic origin data are complex.
Office of Management and Budget (OMB) decision to ask “One or more races,” first implemented for Census 2000.
Small differences in how a question is asked can result in different answers.
Collection methods were not the same and, as expected, produced different results.
Census 2000 provides the official count of  the population.
