  • 02=5 to 9 employees
  • 03=10 to 19 employees
  • 04=20 to 49 employees
  • 05=50 to 99 employees
  • 06=100 to 249 employees
  • 07=250 to 499 employees

Data Element

A 2-digit code that identifies the unit of measurement:

  • 01 Employment: Reported monthly employment data for the third month of the quarter represent the number of covered workers who worked during, or received pay for, the pay period which included the 12th day of the third month.
  • 02 Number of Establishments: Reported number of establishments represents the number of establishments whose activities were reported to the Unemployment Insurance system for the quarter. An establishment is an economic unit, such as a farm, mine, factory, or store, which produces goods or provides services. It is typically at a single physical location and engaged in one, or predominantly one, type of economic activity for which a single industrial classification may be applied. Firm-level counts are not produced due to the dynamic-sizing methodology used in calculating these data.


Data are currently available at the National-level for NAICS industry sectors (2-digit and 3-digit aggregations), firm size classes, and establishment size of change. State-level data are available for most 2-digit NAICS sectors.


A 1-character code that identifies the Rate/Level:

  • L Level-in thousands
  • R Rate


Select one or both periodicity for "Annual" or "Quarterly" data series. Annual data are available for 2-digit NAICS sector data at the National-level and total private sector for State-level data.

Record Type

Indicates the unit of measurement.

Seasonally Adjusted

A 1-character code that indicates the adjustment of time series data to eliminate the effect of intrayear variations which tend to occur during the same period on an annual basis.

  • S Seasonally Adjusted
  • U Not Seasonally Adjusted
