India Census Grids
India is the world's most populous country, yet also one of the least urban. It has long been known that India's official estimates of urban percentages conflict with estimates derived from alternative conceptions of urbanization. To date, however, the detailed spatial and settlement boundary data needed to analyze and reconcile these differences have not been available. This paper presents gridded estimates of population at a resolution of 1 kilometer along with two spatial renderings of urban areas — one based on the official tabulations of population and settlement type (statutory town, outgrowth, census town), and the other on remotel-sensed measures of built-up land derived from the Global Human Settlement Layer. We also cross-classify the census data and the remotely-sensed data to construct an hybrid representation of the continuum of urban settlement. In their spatial detail, these materials go well beyond what has previously been available in the public domain, and thereby provide an empirical basis for comparison among competing conceptual models of urbanization.

1 There are 14 1km grid cells in India with a population count greater than 100,000 persons. All are found within urban areas in the following states: Delhi (3), Gujarat (3), Madhya Pradesh (1), Maharashtra (5), West Bengal (2). 2 Note that the Area grid is supplied as one all-India grid rather than state-specific grids. 3 This data layer is produced and disseminated using two built-up area thresholds
from GHSL: 50% and 1%.
