  1 The list of establishments from which the survey
sample was selected (sampling frame) was developed
from State unemployment insurance reports and is
based on the 2007 North American Industry
Classification System (NAICS). For private
industries, an establishment is usually a single
physical location. For State and local governments,
an establishment is defined as all locations of a
government entity.
