Another critical is temporal granularity. Historical data often agregates over decades or even centers, while thee actual migration events may have expecred in short bursts. A census taken every ten years may miss a wave of migration that haped in between. Researchers can acarets this buy using interpolation techniques or by focussing on on events with high tempor resolution, such ais ship passenger lists or camp strations.
