The modifiable areal unit problem (MAUP) is an issue with spatial data and spatial analysis. The MAUP emerges because individual-level data are aggregated into other spatial units that are arbitrarily defined, with results changing depending on the type of spatial unit under analysis. The most common form of such aggregations is with individuals aggregated into census tracts, or other census-defined units of analysis. If crimes are aggregated differently because the units of analysis change, so will the underlying socioeconomic and sociodemographic characteristics to represent the areas being analyzed. J. Wooldredge analyzed crime patterns considering individuals, census tracts, and official neighborhoods. Though he did find different results depending upon the unit of analysis, the statistical results varied very little for the different aggregations of data.
