   Urban Rural Indicator Code-Tract-level 2010


Description
A measure of how urban a cancer patient's census tract at diagnosis is based on the Census Bureau's identification of urban and rural areas (already collect at county-level). The variable is a 4 code continuum. The measure indicates of the rural nature of the place of residence and can be an indicator of access to recreation, access to food stores, exposures to pollutants, crime levels, social cohesion, etc. Collecting the variable with each decennial census allows for retrospective and cross-sectional epidemiologic analysis.
Rationale
Studies have shown that residents of rural areas have lower screening rates, lower rates of follow-up of abnormal screening tests, higher late-stage diagnosis rates, and differences in cancer treatment patterns. Including tract-level indicators of rural-urban residence in the NAACCR data files will facilitate research in rural-urban disparities and allow researchers to control for rural-urban differences in model-based analysis of cancer risks and outcomes. Using these codes allows cancer registries to release the area-based measure instead of more sensitive information such as address or long/lat. The measure has been tested for uniqueness and the categories selected/aggregated so that identification of individual level census tracts is not possible as long as county is not known. Therefore, unless the researcher can scientifically defend the need for county, the county identifier will not be released in the same database.
Codes

    
        
            1
            All urban-the percent of the population in an urban area = 100%
        
        
            2
            Mostly urban-the percent of the population in an urban area < 100% and ≥ 50%
        
        
            3
            Mosty rural-the percent of the population in an urban area > 0% and < 50%
        
        
            4
            All rural-the percent of the population in an urban area = 0%
        
        
            9
            Unknown or not applicable-census tract not available or tract population was zero at the last decadal census
        
        
            
            
        
    


    Note: This is a derived variable. Currently, the variable is derived during call for data. However, SAS code to derive the variable at the central registry variable for local use is available on the NAACCR website.

1	All urban-the percent of the population in an urban area = 100%
2	Mostly urban-the percent of the population in an urban area < 100% and ≥ 50%
3	Mosty rural-the percent of the population in an urban area > 0% and < 50%
4	All rural-the percent of the population in an urban area = 0%
9	Unknown or not applicable-census tract not available or tract population was zero at the last decadal census
