After World War II, Sosnowiec further developed. On June 1, 1975, the metropolitan area was expanded when the neighbouring locations of Zagórze, Kazimierz Górniczy, Porąbka, Klimontów, and Maczki, became its districts. By 1977 the population of the city reached 200,000. Further growth was accelerated by the construction of [[Katowice Steelworks]], and in 1981, the population of Sosnowiec was 250,000, reaching its peak in 1987, when it was 259,000. Since then, the population has been declining. In 1992, the city became the seat of the [[Roman Catholic Diocese of Sosnowiec]].
