Returns the values of one Statistics Poland Local Data Bank (BDL) variable for many Polish territorial units at once: voivodeships, counties or municipalities, for one year or for every year. Takes a variable id from GUS BDL Variable Search, can be narrowed to one territorial level or to the units under a parent unit, and is paged by unit.
