2018 is the year marked by three momentous anniversaries associated with events that happened exactly 100 years ago: Poland's regaining of independence, the Wielkopolska uprising and the establishment of the Statistics Poland. To celebrate these events, the Statistical Office in Poznań has prepared the publication entitled “Statistical Atlas of Wielkopolskie Voivodship”, a comprehensive overview illustrating social changes and economic development of the voivodship. Socio-economic and environmental aspects presented in the atlas are an important element of the cohesion policy. With the help of charts, cartograms and cartodiagrams, the atlas describes the state and changes observed over time in different thematic areas related to human capital, quality of life, economy and natural environment.
