Urbanisation and differential vulnerability to coastal flooding among migrants and nonmigrants in Bangladesh

Abstract Like much of Asia, Bangladesh will see an urban transition in the coming decades. Yet, its urbanisation will be unprecedented in terms of climate vulnerabilities. Little is known about urbanisation and migrants, in the context of these vulnerabilities, in part because demographic inquiry and training (with a few notable exceptions) has only begun in the last decade to embrace new, spatial data and methods of analysis—especially those involving earth‐observing satellites. This descriptive analysis examines urban change along with low‐elevation coastal zone (LECZ) data as a proxy for flood exposure, using data from satellites, and integrates those features with socioeconomic characteristics and migration information from demographic and health survey data (DHS 2000–2014). We describe where urban change has occurred in…
