A modifiable areal unit problem occurs when point-based spatial data are aggregated into regions and the results depend on how the regions are defined. This can lead to different outcomes depending on the size and shape of the regions used, which can affect the validity of statistical analyses and spatial patterns. A common example is the ecological fallacy, where data about individuals or smaller units are aggregated to larger units, leading to incorrect conclusions about patterns at the larger scale.
