Abstract BACKGROUND: Accurate analysis of health problems facing rural residents depends on how rurality is defined. Health services research relies frequently on the rural urban commuting area (RUCA) codes to estimate rurality at the small area level. We modified the county‐level Index of Relative Rurality (IRR) to the ZIP code level (IRRZIP) to create an alternative small‐area‐level rural classification system. We then compared how the 2 rural classification systems differ in how rural areas and populations are defined and in methodological analysis. METHODS: We linked data for veterans (n = 37,466) who attended the VA Pittsburgh Healthcare System to 2000 United States Census and the US Department of Agriculture's Economic Research Service data. RESULTS: The RUCA and the IRRZIP do not consistently classify the same ZIP code areas and populations as rural. Using the IRRZIP, each 10th increment in increased rurality was associated with a 2.6 increased odds of receiving primary care at a satellite clinic. CONCLUSIONS: The IRRZIP is a straightforward measure that is easy to use and interpret and may be a relevant alternative rural classification system that can be used in health services research.

Background Accurate analysis of health problems facing rural residents depends on how rurality is defined. Health services research relies frequently on the rural urban commuting area (RUCA) codes to estimate rurality at the small area level. We modified the county-level Index of Relative Rurality (IRR) to the ZIP code level (IRR sub(ZIP)) to create an alternative small-area-level rural classification system. We then compared how the 2 rural classification systems differ in how rural areas and populations are defined and in methodological analysis. Methods We linked data for veterans (n = 37,466) who attended the VA Pittsburgh Healthcare System to 2000 United States Census and the US Department of Agriculture's Economic Research Service data. Results The RUCA and the IRR sub(ZIP) do not consistently classify the same ZIP code areas and populations as rural. Using the IRR sub(ZIP), each 10th increment in increased rurality was associated with a 2.6 increased odds of receiving primary care at a satellite clinic. Conclusions The IRR sub(ZIP) is a straightforward measure that is easy to use and interpret and may be a relevant alternative rural classification system that can be used in health services research.
