Network devices - Gas-line system in urban areas
This API provides access to subject P1602 of Poland's Local Data Bank (Bank Danych Lokalnych, BDL), covering the gas-line network infrastructure in urban areas as part of the housing economy and municipal infrastructure archival dataset series. Data are organized as yearly territorial time series, available at multiple administrative levels from voivodship down to gmina, with units identified by official TERYT territorial codes. The dataset is maintained by Statistics Poland (GUS) and forms part of the broader BDL API, which offers structured statistical data for national, regional, and local analysis across Poland.”}HOUSING ECONOMY AND MUNICIPAL INFRASTRUCTURE › ARCHIVAL DATA. Local Data Bank (BDL) subject P1602: yearly territorial series for Poland (voivodship to gmina level), units keyed by TERYT ids.

| Field | Type | Description |
|---|---|---|
| variable_idVariable id | string | GUS variable code identifying the measured gas-network series.GUS variable id selecting the measured series of subject P1602 (the n1/n2 dimension combination): 499=length of working distribution network [km]; 500=active connections to residential and non-residential buildings, total [pcs]; 501=gas consumers (households), in pcs [pcs]; 502=gas consumers (households) heating dwellings with gas [pcs]; 503=gas consumption per conventional units in thousand m3 [thousand m3]; 2190=gas consumption per conventional units in hm3 [hm3]. |
| unit_levelUnit level | integer | Territorial aggregation level, from Poland-wide to gmina.Territorial aggregation level: 0=Poland, 1=macroregion, 2=voivodship (województwo), 3=region, 4=subregion, 5=powiat, 6=gmina. |
| year | integer | Reference year of the yearly value.Reference year of the value (yearly series, back to 1995 for the oldest subjects). Filters server-side via the API's year parameter. |
| unit_idUnit id | string | 12-digit BDL identifier of the territorial unit.12-digit BDL territorial-unit id (macroregion+voivodship+region+subregion+powiat+gmina+type digits). An equality filter pins the unit server-side (unit-parent-id). |
