Density of population of the Indian Empire. Plate 8

Authorship and object

Plate 8 of Constable's Hand Atlas of India (Bartholomew / Edinburgh Geographical Institute, 1893), at about 1:20,000,000, with administrative divisions, major cities and a colour-coded key to population density; prime meridian Greenwich.

Mapping by statistic

This is a choropleth — colour standing for a quantity, here people per unit area, drawn from the imperial census. The land is shown not by its terrain or its history but by a single measured variable spread across it.

The gaze

The thematic map is the administrative gaze made visual. To shade India by population density is to treat the subcontinent as a body of data to be counted and managed — its hundreds of millions abstracted into a graded wash of colour. This is empire as statistics, the census turned into a picture.
