This database contains industry employment and unemployment statistics for California, its regions and MSAs, and most counties based on North American Industrial Classification System (NAICS) categories.  Counties that are part of multi-county MSA are not estimated on a monthly basis, but are estimated annually. Data are not available for all possible combinations of cateogires and areas.  

Unless otherwise indicated, data are not adjusted for seasonal employment variations. See Employment and Unemployment Definitions for category information. See also archived data from 1983 to 2002 based on Standard Industrial Classification (SIC) codes.
