**Overview**

## Background

- The Census 2000 Supplementary Survey (C2SS) was an operational test for collecting long      form-type data.
- Largest household survey ever conducted by the Census Bureau, other than the census long form.
- Provides current information for the country,      50 states and the District of Columbia.

**Notes:**
- Operational feasibility test for collecting long form-type data during, but separately from a decennial census; the data provide an early look at similar data that will be released next summer from the Census 2000 long form.
- As most of you know, the Census is conducted for two primary reasons: 1.) reappportioning the Congress, as mandated by the Article I, Section II of the United States Constitution; and 2.) for distributing more than $200 billion dollars a year in federal funds back to state and local goverments.
- Reapportioning the House of Representatives calls for an accurate count of the population -- age, sex, race, and Hispanic origin.  This type of data is gathered from questions asked of all persons, but is often referred to as short form items.
- Distribution of federal funds is mostly based on the detailed demographic, economic, social and housing characteristics collected by the census long form, which in 2000, went to approximately 1 in 6 households.
- As part of the 2010 re-engineering process outlined by Jay this morning, the Census Bureau seeks to replace a decennial long form, with an annual survey that can more accurately measure the increasingly changing characteristics of our diverse nation. The Census 2000 Supplementary Survey was the first nationwide test of collecting that data during a decennial environment.  
- The operational test was a success. Let me now discuss how the Supplementary Survey data was collected.

## 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 questionnaire;
- Computer Assisted Telephone Interviews (CATI); and
- Computer Assisted Personal Interviews (CAPI).
- Over 96 percent response rate.

**Notes:**
- Go through history of ACS; benefits to continous measurement.
- Discuss differences in collection methods between: Mailout/mailback; CATI and CAPI. 
- Collection of ACS data does not include group quarters populations.
- C2SS to produce estimates for each state and most cities and counties of 250,000 or more.
- C2SS response rate v. Census 2000 long form; historical ACS response rates; explain differences.

## C2SS Data Findings

- First release of Census 2000 Supplementary Survey results to include 107 core tables.
- Narrative and tabular profiles.
- Demographic, economic, social and housing characteristics for the country, 50 states and the District of Columbia.
- Data estimate changes during the 1990s for many characteristics.

**Notes:**
Educational Attainment
- The percent of the population 25 years and over with a Bachelor's degree or more varied from a high of 41.1 percentin the District of Columbia,  34.9 percent in Massachusetts, 33.4 percent in Colorado, and 33.3 percent in Connecticut.  
- The lowest percent of the population 25 years and over with a Bachelor's degree or more are 14.1 percent in West Virginia, 16.6 percent in Arkansas, and 17.2 percent in Kentucky.
Language Spoken at Home 
- Highest was California with 39.5 percent of the population speaking a language other than English, Texas 32.0 percent of the population speaking a language other than English, and New Mexico 35.5 percent of the population speaking a language other than English.
- The lowest percent of the population speaking a language other than English were West Virginia with 2.2 percent, Mississippi 2.9 percent, and Alabama 3.3 percent speaking a language other than English.
Median Housing Value
-The median value of owner-occupied one-family housed in the United States was $120,162.  Comparing the relative ranking of the 50 states and the District of Columbia shows that Hawaii had the highest median home value ($284,536), followed by California ($215,597) and Massachusetts ($192,723).  
- The median property value for West Virginia ($71,952), Arkansas ($72,765), Oklahoma ($73,239), Mississippi($74,862), and North Dakota ($74,947), were the lowest although the values for these states are not statistically different from each other.

## Types of Comparisons

- Comparisons among states using data from the Census 2000 Supplementary Survey.
- National and state comparisons of C2SS data with 1990 census long form estimates.
- Comparisons with Census 2000 long form results in the future.

## The C2SS provides a preliminary look at data similar to those that will be available from the Census 2000 long form.
Legitimate comparisons to 1990 long form can be made, but not for all characteristics.
Group Quarters population included in 1990 long form data, but not in the Supplementary Survey estimates.
Some questions were changed substantially between 1990 and 2000.

- Some questions were changed substantially between 1990 and 2000.

**Comparability: 1990 Census to C2SS**

**Notes:**
- Census 2000 is the official count of the population, and Supplementary Survey data is not intended to replace those counts. 
- Because of differences in the mode of data collection and in the wording of questions, there is not perfect consistency between C2SS data and the 1990 census.
- Population items that are generally comparable include: age, sex, marital status, place of birth, citizenship, year of entry, educational attainment, language spoken at home, veteran status, and commuting to work.
-Housing items that are generally comparable include: year householder moved in, rooms, plumbing facilities, telephone service, vehicles available, house heating fuel, tenure (owner/renter), monthly rent, selected monthly owner costs, and selected monthly renter costs.
-The C2SS provides a preliminary look at data similar to that which will be available next summer from the Census 2000 long form.  An important next step will be to study these data in relation to the long form findings, and whether they suggest the need for additional research.

## Issues regarding collection of race and Hispanic origin data are complex.
Office of Management and Budget (OMB) decision to ask “One or more races” category first implemented     for Census 2000.
Small changes in how a question is asked can result in different answers.
C2SS collection methods were not the same as Census 2000. 
As expected, C2SS results differed.

Fall 2001: 107 core tables for substate areas (most counties and cities with populations of 250,000 or more).
Winter 2001: 700 non-core tables for country, 50 states and the District of Columbia.

## Census 2000 Supplementary Survey feasibility test an operational success.
Data released today are an example of what will be available every year for smaller areas from the American Community Survey beginning in 2004, pending congressional funding.
These data reflect many aspects of how the country has changed over the decade.
