Establishment Size

Establishment size data provide a count of establishments and their size class based on their number of employees, for each Washington industry and for each county.

Every year, we tabulate the number of establishments operating in Washington state and sort them by size. We provide counts by industry sector and subsector and for each county. The data are screened to protect confidentiality.

The data are useful in understanding the distribution of jobs between small and large establishments and are helpful for tracking job growth by establishment size.

What is the data source?

We use first quarter data from the Quarterly Census of Employment and Wages (QCEW), Enhanced Quarterly Unemployment Insurance file to build the establishment size dataset. 

How often are the establishment size data updated?
