Ethnic-confessional cyclicality and continuity in the Petroșani Depression in the period: 1850–2011

The aim of the study is to comprise in one work the cyclicality and ethnic and religious continuity of the Petroşani Depression between 1850-2011. In the second half of the 19th century, the depression was subjected to cycles of colonization that had consequences for the ethnic and religious structure. The ethnic and religious continuity was preserved throughout this period, even though after 1930, some of the settlers remigrated to their birthplace. Compared to the late 19-century censuses, the herds have fallen to 2011, but none of the ethnics and confessions have completely disappeared. The statistical data used were taken from the literature mentioned during the work and on the online platform of the National Institute of Statistics. The geographic information systems were used to achieve the geographical position map at the county and national level of the Petroşani Depression.
