This set of quarterly cubes provides employee population data. The numbers reflect the actual number of employees at the end of a quarter but, for many agencies, may actually reflect employment at the end of the pay period just prior to the end of the quarter. The scope of this raw data set includes all data elements used in the creation of the FedScope Employment Cube (http://www.fedscope.opm.gov/). The following workforce characteristics are available for analysis: Agency, State/Country, Age (5 year interval), Education Level, Gender, GS & Equivalent Grade, Length of Service (5 year interval), Occupation, Occupation Category, Pay Plan & Grade, Salary Level ($10,000 interval), STEM Occupations, Supervisory Status, Type of Appointment, Work Schedule, Work Status, Employment, Average Salary, and Average Length of Service. The OPM Enterprise Human Resources Integration-Statistical Data Mart (EHRI-SDM) is the source for all FedScope data. Data is processed on a quarterly basis (i.e. March, June, September and December).
