MERIC in cooperation with U.S. Bureau of Labor Statistics provides three types of industry employment information: ES202, LDB and CES. These numbers are statistical estimates. Due to different data collection methods and the recent conversion from SIC to NAICS the values for overlapping data may not match.
Quarterly Census of Employment and Wages (ES202)
The Quarterly Census of Employment and Wages Program is a cooperative program involving the Bureau of Labor Statistics (BLS) of the U.S. Department of Labor and the State Employment Security Agencies (SESAs). The program produces a comprehensive tabulation of employment and wage information for workers covered by State unemployment insurance (UI) laws and Federal workers covered by the Unemployment Compensation for Federal Employees (UCFE) program. Publicly available files include data on the number of establishments, monthly employment, and quarterly wages, by NAICS industry, by county, and by ownership sector, for the entire United States. These data are aggregated to annual levels, to higher industry levels (NAICS industry groups, sectors, and supersectors), and to various geographic levels (national, State, and Metropolitan Statistical Area (MSA)).
Longitudinal Data Base (LDB) 1990 - 2000
To implement the North American Industry Classification System (NAICS), the Bureau of Labor Statistics and State partners are assigning NAICS codes to the approximately 8.2 million employers covered by State unemployment insurance (UI) laws. Employer UI reports are the basis of the Longitudinal Data Base (LDB), which serves as the frame for BLS establishment surveys. The NAICS conversion includes a multi-year process of gathering information from employers in order to assign NAICS codes. The collection procedure allows for interim assessment of the effect of the NAICS conversion on industry classification and BLS products. When employers do not provide adequate information for industry classification, BLS will assign NAICS codes based on the distribution of those codes across other establishments with the same Standard Industrial Classification (SIC) and other characteristics. These procedures will be applied to current and, to the extent feasible, historic data on the LDB including establishments that are out of business. This provides a frame for surveys requiring stratification by NAICS and aids in the conversion from SIC to NAICS for ongoing surveys. In addition, the availability of a continuous history with NAICS codes will permit seasonal adjustment and other time-series analysis of the data.
Current Employment Statistics (CES)
This survey of payroll records covers over 300,000 businesses on a monthly basis and provides detailed industry data on employment, hours, and earnings of workers on nonfarm payrolls for the States and Nation.
