In 2018, 100 years have passed since the establishment of the Central Statistical Office. On this occasion, the Statistical Office in Warsaw prepared the “Statistical Atlas of Mazowieckie Voivodship” presenting the spatial diversity of social and economic phenomena in the region. The Mazovia is considered one of the most internally diversified voivodships in Poland. This results from the dominating position of Warsaw and dynamically developing metropolitan area surrounded by areas struggling with the problems of depopulation, unemployment and low entrepreneurship.
