The Census of Employment and Wages (CEW) data from the Bureau of Labor Statistics (BLS) with added imputed values for non-disclosures can be examined in the Data Library. Because of the level of detail and historic data available, the Employment & Wages by NAICS data is perfect for establishing trends and running statistical analyses. This Imputed CEW data is useful for completing trend analyses and deep dives into U.S. wage and salary employment and income information. Drilling down into specific Industry data allows for users to more precisely define the Industry they wish to analyze at a granular level.
The BLS collects a quarterly count of wage and salary employment and wages across the U.S. called the Quarterly Census of Employment and Wages (QCEW). It uses data that is reported by employers covering more than 95% (see following section for more details on sector coverage) of jobs across the country. Data is then made available at the county, state, and national levels. The BLS also releases the annual CEW data. The data contains wage and salary employment, wages, and establishments in a given sector and area (down to the county level) and contains this information at the 6-digit NAICS level. This allows for even greater detail in specific modeling scenarios. However there are certain non-disclosures within their data; IMPLAN adds value by filling in these non-disclosures based on existing data to be able to provide a complete picture.
These data do not include proprietors nor do the wages include benefits, payroll taxes, or any other supplements to wages. The data set includes all employees covered by Federal Social Insurance (SI) programs, and thus do not fully cover all sectors: major exclusions from SI coverage include 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 (primarily religious organizations). According to the Bureau of Economic Analysis (BEA), the following sectors are also undercovered in the CEW data: Support Activities for Agriculture and Forestry; Shellfish Fishing; Finfish Fishing; Religious Organizations; Colleges, Universities, and Professional Schools (student employees specifically), and Private Households.
The data are reported for all NAICS code levels (6-digit to 2-digit) for the latest NAICS scheme, with complete sectoral roll-up for any given geography (that is, all 6-digit NAICS codes will sum to their 5-digit parent NAICS code, and so forth). The data are reported for four ownership types: Federal Government, State Government, Local Government, and Private (ownership codes 1, 2, 3, and 5, respectively). The data contain their associated disclosure codes, indicating whether the value was published publicly by the BLS (disclosure code = 0) or estimated by IMPLAN (disclosure code <> 0).
IMPLAN uses four levels of preference when estimating non-disclosed CEW values, depending on the availability of each option for a given geography, NAICS code, and year: 1) disclosed raw CEW data from the previous year, projected to the current data year; 2) Census County Business Patterns (CBP) employment per establishment data, which are also reported on a NAICS basis but are a year lagged relative to the latest CEW data, applied to current establishment counts from CEW; 3) raw CEW data from two years prior, projected to the current data year; 4) state or U.S. ratios (employment per establishment, wages per employment, etc.) calculated from disclosed raw CEW data for the latest year. First estimates are adjusted to ensure roll-up across NAICS levels and to meet certain geographic and ownership type requirements.
