The Modifiable Areal Unit Problem (MAUP)

The Modifiable Areal Unit Problem (MAUP) refers to the challenges that arise when analyzing data that is collected across different geographic areas, such as counties or neighborhoods. The issue is that the results of an analysis can change depending on how these areas are defined or grouped. For example, combining data from larger regions may hide local trends, while smaller regions might show variability that isn’t representative of a larger context. Thus, MAUP highlights the importance of considering how geographic boundaries can influence conclusions drawn from spatial data.
