Modifiable Areal Unit Problem (Openshaw, 1984)
Scale and delineation mismatch between:
- Underlying process (e.g. individuals, firms, shops)
- Unit of measurement (e.g. neighborhoods, regions, etc.)
In some cases, it can seriously mislead analysis on aggregated data (e.g. Flint, MI!!!)
Always keep MAUP in mind when exploring aggregated data!!!
