The population of Altstadt as well as related information and services (weather, Wikipedia, Google, images).
Source: Boundaries and population of settlements are computed by »City Population« using population figures in a 100m grid provided by the Statistisches Bundesamt Deutschland (web) and using geospatial data of the Bundesamt für Kartographie und Geodäsie (web). The settlements are delimited by unsettled and not built-up areas as well as by municipal boundaries.
Because of the computation method, the above population figures are not exact and therefore rounded. Area figures are derived from geospatial data.
