Why would a geographer want to collect a city's historical information like census data and natrual disaters

A geographer would collect a city's historical data about the census and the occurrences of natural disasters in order to study the impact of demographics and calamities on the geographical features of the region.

Explanation:

The discipline of Geography is made up of two broad classes. One is Physical Geography and the other is Human Geography. These two classes are interdependent and their functioning is coherent. The study of a region's Geography is incomplete without the studies of the region's demography and the occurrences of natural disaster in the region, for their impact on the regional geography is immense.
