QCEW Data Overview
QCEW is the Quarterly Census of Employment and Wages. The program originated in the 1930s, and was known as the ES-202 program until 2003 when the current QCEW name was adopted. The primary economic product is the tabulation of employment and wages of establishments which report to the Unemployment Insurance (UI) programs of the United States. Employment covered by these UI programs represents about 97% of all wage and salary civilian employment in the country.
Data File Accessibility
There are several different ways to get to data for earlier periods.
For more information on the industry classification systems QCEW uses, refer to the QCEW industry coding page.
Additionally, information on historical data availability from QCEW database tools can be found on the QCEW Data Availability page.
The complete QCEW program data file is too large to be published via the current customized-table database. The complete set of QCEW data can be downloaded in various formats - ENB and END are two dense data formats used by QCEW. These files can be read by or imported into a variety of data analysis and statistical tools, such as Excel, SAS or Access. Please see the QCEW flat file helper applications page. For more information about the different aspects of these files, please visit the data guide page.
These data are also available in the .csv format which is more familiar for many users. Again, see the data guide for details.
The finest level of geographic detail is the county-industry level, as aggregates of establishments classified to varying degrees of industry detail. While the input data are coded with meaningful address locations, the data are generally unavailable at greater detail. The QCEW program is constrained by the need to protect the confidentiality of data provided by employers, and richer geographic detail would threaten that confidentiality. Even the county by industry data cited above is at the margin of being disclosable - approximately 60 percent of the most detailed level data are suppressed for confidentiality reasons.
Beginning in the 4th quarter of 2017, QCEW accelerated the publication of its news release, available now 2 weeks before the full data release for all areas and industries. BLS has changed the release schedule for two reasons. The first is to share QCEW data for all states faster. The second is to release the data before the Bureau of Economic Analysis (BEA) publishes quarterly Gross Domestic Product (GDP) data, which uses the most recent QCEW wage data. More information about this can be found on this page.
QCEW data are available quarterly and annually (see our release calendar), between five and six months after the end of the quarter. Each release includes monthly employment levels as well as quarterly establishment counts and quarterly wage information.
Quarterly and Annual data are preliminary (denoted with a 'p' in the production database output) during the current reference year, then finalized with the publication of the following year's first quarter of data. Please note that revisions between preliminary and final data are usually minor in QCEW.
To receive notifications regarding the QCEW news releases, please subscribe to the BLS News Service, and select the County Employment and Wages press releases under Employment and Unemployment. Please use the contact page to request special notifications and announcements from QCEW.
NOTE: For information on historical data availability from QCEW database tools, go to the QCEW Data Availability page.
Understanding QCEW Data
There are two common reasons for users to see such differences.
No. The QCEW program does not publish data based on occupations. The published employment and wage levels only reflect an entire establishment, which may consist of multiple occupations and jobs.
For occupational data, visit Occupational Employment Statistics (OES) web pages.
Many major shifts in employment or wage levels are the result of various economic activities. Examples of what might cause these shifts are establishment openings or closings, and major establishment expansions or contractions.
Shifts can be caused by changes in the dominant economic activity at a particular establishment. For example, an establishment may make two products that are properly classified in two different industries. The correct classification for the establishment as a whole is the dominant activity. If, over time, production of the secondary product increases beyond that of the initial dominant product, the industry classification of the establishment should be changed. Another factor is the relocation of an establishment from one area to another. In some cases, the QCEW program is not made aware of the changes underlying these classification updates until a significant time has elapsed since their occurrence.
Between fourth and first quarter, QCEW incorporates many changes in the basis of reporting. These changes can be as simple as the correction of an erroneous industry or county classification, or as complicated as incorporating the changes large employers make when reporting data for numerous worksites.
Multi-unit employers may also choose to report in greater detail after only previously reporting as a single unit. For instance, a chain store may have reported as a single large corporation for years but now reports as having 50 locations throughout the state. When the employer changes its reporting basis to multiple worksites or establishments from consolidated reports, the establishment count of that industry will experience a sudden jump.
Prior to first quarter 2016, public universities in the state of Oregon were classified in QCEW under state government ownership. Beginning with data for first quarter 2016, QCEW classifies these establishments in local government ownership. The industry classification for these institutions has not changed.
This change in ownership resulted from the passage in 2011 and 2013 of state legislation which created a new legal entity called "universities with governing boards." Public universities in Oregon were reorganized in 2014 and 2015 under this new legal entity. They are now independent public bodies that can establish their budgets without state approval. This new political subdivision will be classified under local government ownership.
Oregon Senate Bills (SB) 242 and 270 enacted this change. SB 242, passed in 2011, created a means for public universities to establish governing boards. SB 270, passed in 2013, designated Oregon's public universities as universities with governing boards.
The ownership of these universities transferred from the state to the new entity. Universities are no longer subject to most of the rules and regulations that control state government units and they can now set their own budgets, set their own employment levels, and solicit funding from nongovernmental entities. These universities also have the option of paying into the Local Government Employee Benefit Trust Fund to cover their Unemployment Insurance needs.

In some cases, these indicators may represent an industry or area with no reported or zero economic activity.
However, in many cases these indicators represent data suppressed to protect the identity, or identifiable information, of cooperating employers. Most of the suppressed data are provided by or are substantially attributable to a single large employer. Various statistical techniques are used to limit to the possibility of using published data to derive sensitive identifiable information. For more details on these concepts, see FAQ #14.
In many cases, suppressions may also be necessary for otherwise disclosable data that may be used to derive sensitive information from another industry or area. However, published totals of higher-level aggregations, when disclosed, include the suppressed lower-level data.
Additionally, here are some general guidelines for understanding disclosure codes and related ideas in the data:
2004-forward QCEW CSV Files
2001-2003 QCEW CSV Files
1990-2000 QCEW NAICS-Based CSV Files
1975-1990 QCEW NAICS-Based CSV Files and 1975-2000 SIC-Based Data CSV Files
NOTE: QCEW prioritizes counties over MSAs
This can affect the availability of QCEW MSA data, regardless of size. If there is a county suppression within the MSA then we have to withhold data for either another county or the MSA. This prevents discovery by subtracting the remaining counties from the MSA. This is often why an MSA value will be withheld.
For more information about this issue, please refer to the documents linked in FAQ#14.
In accordance with the BLS Confidentiality policy, data reported under a promise of confidentiality are published in a way so as to protect the identifiable information of respondents. BLS withholds the publication of UI-covered employment and wage data for any industry level when necessary to protect the identity of employers. Totals at the industry level for the states and the nation include the undisclosed data suppressed within the detailed tables without revealing those data. QCEW confidentiality concepts and practices are largely based on the Statistical Policy Working Paper 22 (PDF) developed by the Federal Committee on Statistical Methods.
For more information about Confidentiality concepts, as it relates to QCEW data disclosure, please see this document about Confidentiality and Data Disclosure.
There are two main reasons for establishment count discrepancies between QCEW and other programs. First, while QCEW program only reports the predominant economic activity, other programs may choose to also include non-predominant economic activity as part of its count.
For instance, a metal parts manufacturing factory would be classified under manufacturing. However, this factory may also perform plating on the parts as part of a package or deal for its end-users. Under the QCEW count, this establishment would be counted only under manufacturing, but not plating because it is not the factory's predominant economic activity or output.
The second reason of the discrepancy is the differences in reporting practices of multi-establishment firms. State UI laws vary with regard to requiring establishment breakouts. Even without legal obligation, many multi-establishment employers break their reports to the establishment level via Multiple Worksite Report. When an employer begins reporting via multiple worksite reports, often after only via consolidated reports, the establishment count jumps.

Although BLS receives QCEW files from all 53 entities in a timely manner, the files contain estimates for missing respondents. Information about this process is available on the QCEW Imputation Methodology page.
The QCEW employment count is a total derived from quarterly contribution reports filed by almost every employer in the U.S., Puerto Rico and the U.S. Virgin Islands. It counts only filled jobs, whether full or part-time, temporary or permanent, by place of work. The quarterly reports include the establishment's monthly employment levels for the pay periods that include the twelfth of the month.
Because the QCEW data is based on an establishment census which counts only filled jobs, it is likely that a multi-job holder will be counted two or more times in QCEW data.
Major exclusions from UI coverage include self-employed workers, most agricultural workers on small farms, all members of the Armed Forces, elected officials in most states, most employees of railroads, some domestic workers, most student workers at schools, and employees of certain small nonprofit organizations.
For more information on employment concepts:
NOTE: QCEW includes about half of the U.S. agricultural sector. Agricultural (farm) employment and wage data can be found in NAICS 111 Crop Production, 112 Animal Production and Aquaculture, 1151 Support Activities for Crop Production, and 1152 Support Activities for Animal Production. QCEW data for these industries can be retrieved easily using the QCEW Data Viewer, Open Data Access, or via Downloadable Data Files.
Under most State laws or regulations, wages include bonuses, stock options, severance pay, profit distributions, cash value of meals and lodging, tips and other gratuities, and, in some States, employer contributions to certain deferred compensation plans such as 401(k) plans.
Covered employers in most States report total compensation paid during the calendar quarter, regardless of when the services were performed. A few State laws, however, specify that wages be reported for or based on the period during which services are performed rather than the period during which compensation is paid.
The QCEW program produces employment and wage data by establishment size for the first quarter of each year.
Data on employment and job growth by company size is available from the Business Employment Dynamics (BED) program. An alternate source is the Census Bureau enterprise size data from its Statistics of U.S. Businesses program.
For more information on the differences between establishment, company and employer, please refer to Question #22 on this page.

There are no machine readable versions of that data available at this time. For QCEW data prior to 1975, please contact your local Federal Depository Libraries.
For detailed information on the various codes and titles used, please refer to our Data File Documentation page.
QCEW data for Metropolitan Statistical Areas (MSAs) are based on:
NOTE: Since QCEW is not a time series product, switching to new versions of MSA definitions creates breaks that reduce the utility of QCEW MSA data. QCEW practice is to switch to a new definition when results from each decennial census stabilize. Based on past history, the next update would likely incorporate MSA definitions released in 2023.
Location quotients (LQs) are ratios that allow an area's distribution of employment by industry, ownership, and size class to be compared to a reference or base area's distribution. The reference area is usually the U.S. and the reference or base industry usually includes all industries in the economy.
For more information, please visit QCEW Location Quotient Details.
Each of these terms is used to refer to employing entities for which statistical information is collected, and for which statistics are collectively published. An establishment is commonly understood as a single economic unit, such as a farm, a mine, a factory, or a store, that produces goods or services. Establishments are typically at one physical location and engaged in one, or predominantly one, type of economic activity for which a single industrial classification may be applied. A firm, or a company, is a business and may consist of one or more establishments, where each establishment may participate in different predominant economic activity.
QCEW conducts various activities to increase the amount of data reported at the establishment level; however, some firms with multiple establishment may choose to report as a single entity.
The QCEW data that are available stratified by establishment size are discussed on our size availability page. QCEW uses standard establishment size strata for it's tabulations. These size strata use codes and titles described in our documentation for NAICS coded data and SIC coded data. The size code standards were established by the Office of Management and Budget (OMB) in a 1982 directive, The Comparability of Statistics on Business Size.
For company or firm-level data, please visit the Business Employment Dynamics (BED) program.
