Bureau of Labor Statistics (BLS) – QCEW

The Quarterly Census of Employment and Wages (QCEW) program produces quarterly employment and wage data by location and industry.

BLS Handbook

Handbook of Methods, Chapter 5, Employment and Wages covered by Unemployment Insurance publishes a quarterly count of employment and wages reported by employers covering 98 percent of U.S. jobs, available at the county, MSA, state and national levels by industry.


The North American Industry Classification System (NAICS) groups establishments into industries based on the activities in which they are primarily engaged using a six-digit hierarchical coding system to classify all economic activity. It is a joint venture with statistical agencies of the United States, Canada, and Mexico. Every five years the BLS revises some Industry or NAICS codes to better reflect current industries. The most recent revision occurred in 2022.

Multiple Worksite Report (MWR)

The Multiple Worksite Report (MWR) is supplemental to the Quarterly Contribution Report (QCR) which is filed with Unemployment Insurance (UI). The MWR form is used to collect separate employment and wage data for each of the employer's establishments, which are not detailed on the UI report. Employers with multiple locations under one UI account with a total of 10 or more employees combined in their secondary locations are requested to complete this report.

Annual Refiling Survey (ARS)

The Annual Refiling Survey (ARS) is used to ensure the highest possible quality of the NAICS, location, and ownership codes. Businesses with private ownership and four or more employees are surveyed every three years to ensure accurate industry and location information is assigned.
