Labor Market Information Resources and Data: Home | By Customer | By Subject | By Geography | Data Library | Online Services
The Quarterly Census of Employment and Wages (QCEW) program produces a comprehensive tabulation of employment and wage information for workers covered by California Unemployment Insurance laws. The QCEW program serves as a near census of monthly employment and quarterly wage information at the state and county levels and provides the most detailed industry data available. The QCEW data is usually published six months after the end of the quarter.
The QCEW data is also called Detailed Industry Data and Employment and Payroll Data. It was formerly known as the ES202 Program data.

Business Employment Dynamics (BED)
The Business Employment Dynamics (BED) data tracks the expansion and contraction of employment for private businesses. These employment changes - gross job gains (expansions and openings) and gross job losses (reductions and closures) - are components of the net change in employment at the establishment level.
Annual Refiling Survey (ARS)
The Annual Refiling Survey (ARS) verifies and updates the NAICS, physical location address and ownership codes of all establishments on a three-year cycle.

Multiple Worksite Report (MWR)
Each quarter, the Multiple Worksite Report (MWR) asks most multi-location employers to provide employment and wage data for all their establishments covered under one Unemployment Insurance (UI) account in California. Data from the MWR enables our agency to monitor and analyze conditions of business activities by California’s geographic area and industry.
