On November 20, 2024, the Quarterly Census of Employment and Wages (QCEW) suspended publication of industry and substate data for Colorado due to data quality concerns. These data quality concerns were due to ongoing issues with the modernization of the state’s unemployment insurance (UI) system. Because the QCEW microdata are fundamentally a byproduct of state UI systems, QCEW data quality is sensitive to changes in these systems.
The quality concerns with Colorado data have been sufficiently addressed to resume QCEW publication. Therefore, on February 19, 2025, QCEW resumed publication of substate and industry employment and wage data for Colorado with the issuance of the County Employment and Wages news release for third quarter 2024.
QCEW data serve as critical inputs into estimates produced by the Occupational Employment and Wage Statistics (OEWS). OEWS uses QCEW employment data—which provide comprehensive counts of nonfarm payroll employment—to adjust estimates to represent all employment that is in scope for the OEWS survey. Because of the processing time for the annual OEWS release, the updated Colorado employment data could not be incorporated by the OEWS release date. As a result, the May 2024 OEWS data released on April 2, 2025, do not include data for Colorado and its areas. The OEWS national data may have been marginally impacted by the quality issues in Colorado. OEWS plans to release Colorado estimates at a later date.
