Establishment Size Data Available from QCEW
In addition to richly detailed employment and wage data, the Quarterly
Census of Employment and Wages (QCEW) program produces data on
establishments, employment, and wages stratified by size of establishment for the
first quarter of each year. The size class of each
establishment is determined by the March employment level. These size
class data are available at the national level by 6-digit NAICS, and at
the State level by NAICS sector. The most complete versions of these data are
available from the QCEW data files.
A limited portion of the data are
available from the publication database, and from Tables 3 and 4 of
the bulletins of the the Employment and Wages, Annual
Averages archive. For more information on
the QCEW data files, see our data guide.
It is important to note that each establishment of a
multi-establishment firm is tabulated separately into
the appropriate size category. The total employment level of the reporting
multi-establishment company is not used in the size tabulation.
An alternate source of data by company or firm size is the
BLS Business Employment Dynamics program which produces tabulations
on employment levels as well as employment dynamics stratified by firm size. Two popular tables
from that program are
Distribution of private sector employment by firm size class and
Distribution of private sector firms by size class. These tables are done for the first quarter of
each year, beginning with data for 1993.
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.
