Today: Brief Overview of Census Data and Resources

Huge data collection budget ($5-12 Billion annually) Even more money allocated on basis of data

collection (~ $400 Billion annually) Most widely used social science data

– High quality sample frames– Large samples sizes, small geographies– Consistency

Why is the Census Bureau important?

Where’s all the interesting stuff?

In 2000 (and earlier) censuses, the census used more than one form:

A “short” form, which asked basic demographic data, just like the 2010 census form (AKA – 100% data)

A “long” form, which collected both the items on the short form and a broader set of items about income, education, ancestry, language, disability, employment, etc.. (AKA – sample data)

Now, decennial census focuses solely on basic demographic data, and social and economic data are collected in the American Community Survey (ACS)

Broad Data Collections

American Community Survey Continuous Replacement for the “long form” of the decennial

census. HH sample fully implemented in January 2005,

annual sample of around 3 million. Multi-mode: mail, CATI, CAPI Multiple Data releases

– 1 year, 3 year, 5 year, PUMS

ACS Content - Basic

ACS: Design of the Sample

Annual Sample Size of 3 million addresses Series of Monthly Samples of 250,000 addresses HU sample in each of the 3,141 Counties Areas with smaller populations sampled at higher

rates than those with larger populations HU Address sampling rate set by Block Final sampling rate varies between 1.6% and 10% No HU address can be sampled more than once in 5

years

Distribution Formats

Like former decennial census data, released in both aggregate and microdata formats

Because of change to continuous sampling, however, aggregate data released at different geographic levels with differing collection frames

Survey of Income and Program Participation

The Survey of Income and Program Participation (SIPP) program, initiated in 1983, is a longitudinal, multi-panel survey primarily of adults in households in the United States.

Sampled households are interviewed at least nine times at four-month intervals and followed over the life of the panel. New samples (panels) are drawn periodically, ranging in size from around 13,000 HHs to around 40,000 HH’s. (annually 1984-1993; 1996, 2001, 2004, 2008)

The SIPP attempts to interview all members age 15 and older in the household during the first wave of interviewing. Subsequent interviews may be in-person or by phone, with the same interviewer speaking to the same respondents.

New members who join the household are interviewed after they join; departing members are interviewed at their new address.

Survey of Income and Program Participation

SIPP information falls into two categories: the core information, and other questions (found in "topical modules") that produce in-depth information on specific subjects and are asked at only one or two interviews.

SIPP core content covers demographic characteristics, work experience, earnings, program participation, transfer income, and asset income.

Current Population Survey

The Current Population Survey (CPS) is a monthly survey of about 50,000 to 65,000 households conducted by the Bureau of the Census for the Bureau of Labor Statistics. The survey has been conducted for more than 50 years.

The CPS is the primary source of information on the labor force characteristics of the U.S. population. The sample is scientifically selected to represent the civilian noninstitutional population.

Households are in the survey eight times: four consecutive months, eight months off, and then a final four months.

Estimates obtained from the CPS include employment, unemployment, earnings, hours of work, and other indicators. They are available by a variety of demographic characteristics including age, sex, race, marital status, and educational attainment. They are also available by occupation, industry, and class of worker.

Supplemental questions to produce estimates on a variety of topics including school enrollment, income, previous work experience, health, employee benefits, and work schedules are also often added to the regular CPS questionnaire.

American Housing Survey

Provides information on the size and composition of the housing inventory in the United State, neighborhood characteristics, characteristics of occupants. household characteristics, income, housing and neighborhood quality, housing costs, equipment and fuels, size of housing unit, and recent movers.

The AHS returns to the same housing units year after year to gather data; therefore, this survey is ideal for analyzing the flow of households through housing.

Sample of ~ 65,000 Collected for HUD Separate national (fixed sample for ~50,000, followed since 1985) and

metropolitan samples (~3,200 – 4,800 per area, every 6 years, 12-14 areas/year)

More detailed data, less geographic detail, than census

Consumer Expenditure Survey

The Consumer Expenditure Survey (CES) provides information on the buying habits of American consumers and also furnishes data to support periodic revisions of the Consumer Price Index. A new sample is drawn annually, and includes about 60,000 households.

The survey consists of two separate components: (1) a quarterly Interview Survey in which each consumer unit in the sample is interviewed every three months over a fifteen-month period, and (2) a Diary Survey completed by the sample consumer units for two consecutive one-week periods.

The quarterly interview gathers retrospective data on purchases, and focuses on regular and large expenses.

The Diary Survey contains consumer information on small, frequently-purchased items such as food, beverages, food consumed away from home, gasoline, housekeeping supplies, nonprescription drugs and medical supplies, and personal care products and services. Participants are asked to maintain expense records, or diaries, of all purchases made each day for two consecutive one-week periods.

Selected Other Data

National Crime Victimization Survey– 48,000 addresses in 809 PSU’s in US– Operating since 1972– 7 interviews over 3 ½ year period

National Corrections Reporting Program – Prison Admission and discharges. Variables include incarceration history, current offenses, and

total time served. Background information on individuals includes year of birth, sex, age, race, Hispanic origin, and educational attainment.

A variety of surveys for NCHS, e.g.– National Health Interview Survey– National Hospital Discharge Survey– National Survey of Ambulatory Surgery
