It provides annual average data from the CPS for census regions and divisions, the 50 States and the District of Columbia, 50 large metropolitan areas, and 17 central cities. These data include employment and unemployment by selected demographic and economic characteristics.
The official concepts and definitions used in the Current Population Survey (CPS) are followed. For a complete description, see Definitions of Labor Force Concepts (PDF).
The data in the LA series are the official data used for Federal fund allocations and are based on a statistical methodology which uses data from a variety of sources. Data for approximately 6,880 geographic areas are developed in this manner and included in this database, including for all counties and cities of 25,000 or more, thus meeting the data needs of other Federal programs. The methodology is consistent across states, so areas can be compared to one another. Data are available on a monthly and annual basis, with preliminary estimates published within two months from the reference period. No demographic data are available from this series.
The GP series provides data for only 50 large metropolitan areas (MAs) and 17 cities. These annual average data come directly from the Current Population Survey (CPS). The CPS sample is not large enough to provide reliable data for all areas (in fact, many areas contain no sample), nor is the reliability consistent among the areas published. These CPS estimates are the only current source of information on demographic and detailed economic characteristics for these areas.
People who have lost a job make up a large but varying portion of those classified as unemployed each month. There are also persons who have voluntarily left jobs, persons who have newly entered or re-entered the labor force but not yet found a job, and persons who have recently completed temporary jobs and are looking for employment. For a more detailed description of these labor force concepts, see Definitions of Labor Force Concepts (PDF).
The CPS is a monthly sample survey of approximately 60,000 households (nationally) conducted by the Bureau of the Census for the Bureau of Labor Statistics. It is the source of much key labor market data, including the U.S. unemployment rate. For more information see Current Population Survey.
"Household" data, as from the Current Population Survey (CPS), pertain to individuals and relate to where they reside. "Establishment" data, such as those from the Current Employment Statistics, a survey of businesses, pertain to jobs (persons on a payroll) and where those jobs are located. The data developed through the LAUS program are based on the household concept of the CPS. For information on these surveys and how they differ, see Household vs. Establishment Series.
National data come from all 60,000 household in the Current Population Survey. The survey sample size is not large enough at the local, or even state, level to provide the same level of detail in the estimates. Note that National data are NOT the sum of local area estimates.
Detail for race and Hispanic or Latino ethnicity groups will not add to totals because data for the "other races" group are not presented and because Hispanics (an ethnic category, rather than a race) are included in both the Black and White population groups.
The best source for detailed data for small areas is the U.S. Census Bureau. Data from Census 2000 and the 1990 Census can be accessed through American FactFinder.
