The data are produced based on the results of the 2011 Population and Housing Census and the building data from the Estonian National Topographic Database. Data are available in the statistics mapping application:

A built-up locality is a built-up area where the distance between buildings is no more than 200 metres and where there are at least 200 inhabitants. Hence, the borders of built-up localities do not coincide with those of settlement units. Based on the data from 2011, there are 369 such built-up areas in Estonia, where approximately 85% of the enumerated permanent residents live.
