Population in dwellings
This API provides access to subject P1717 of Poland's Local Data Bank (Bank Danych Lokalnych, BDL), maintained by the national statistical office GUS. It covers population in dwellings as part of archival housing economy and municipal infrastructure statistics, offered as yearly territorial time series. Data are structured by administrative level, from voivodship down to gmina, and units are identified using TERYT territorial reference codes. The dataset supports analysis of housing-related population distribution across Poland's administrative divisions over time.HOUSING ECONOMY AND MUNICIPAL INFRASTRUCTURE › ARCHIVAL DATA. Local Data Bank (BDL) subject P1717: yearly territorial series for Poland (voivodship to gmina level), units keyed by TERYT ids.
