Why Follow BLS?
Each month, the Bureau of Labor Statistics (BLS) releases monthly employment estimates for over 1,000 industries from its Current Employment Statistics program. The program includes data from two surveys, one of individual households and one of business establishments. Data from the household survey are used to derive the monthly unemployment rate, while the business establishment survey, which ASA tracks, estimates industry employment levels. These employment data are considered indicators of current economic trends. Industries included in the BLS establishment survey are identified by the North American Industry Classification System (NAICS). The system includes 20 “super sectors,” under which similar industries are grouped and then categorized by codes (unique numeric identifiers).
