Overview
An area's economic and social characteristics have significant
effects on its development and need for various types
of public programs. To provide policy-relevant information
about diverse county conditions to policymakers, public
officials, and researchers, ERS has developed a new set
of county-level typology codes that captures differences
in economic and social characteristics. This 2004 County
Typology is a major update and revision of ERS's 1989
county typology.See the typology
code chapter in the measuring rurality briefing room
for more information, links to maps, and methodology.

data sources, and documentation for background on
the typology codes. Please note that 39 counties have
changed farm dependency status from the preliminary group
posted in May 2004. A discussion of these changes may

In March 2009, a variable indicating persistent child poverty
was added to the 2004 file.
