Urban/Rural 2013

DD_category: 
PUF Data Item Name: 
UR_CD_13
length: 
1
Allowable values: 
1 - 9
Description: 
Area-based measure of rurality and urban influence, using the typology published by the USDA Economic Research Service.
Registry Coding Instructions: 

None.

Analytic Note: 

This item was estimated by matching the state and county FIPS code of the patient recorded at the time of diagnosis against 2013 files published by the United States Department of Agriculture Economic Research Service (http://www.ers.usda.gov/data-products/rural-urban-continuum-codes).  
 
Rural-Urban continuum codes form a classification scheme that distinguishes metropolitan (metro) counties by the population size of their metro area, and nonmetropolitan (nonmetro) counties by degree of urbanization and adjacency to a metro area or areas. The metro and nonmetro categories have been subdivided into three metro and six nonmetro groupings, resulting in a nine-part county codification. The codes allow researchers working with data to break such data into finer residential groups beyond a simple metro-nonmetro dichotomy, particularly for the analysis of trends in nonmetro areas that may be related to degree of rurality and metro proximity.
 
Since labels for the 2013 classification codes are the same as the 2003 labels, a direct comparison with the 2003 Urban/Rural codes may be made.
