Present population structure of Central Pomerania is a consequence of demographic transformations introduced in the post-war period. The population of the described region is heterogenic and has been combined by people who came from different parts of Poland, autochthons and generations born in this particular area. However the settlers from Central Poland (41.9%) and people who came from abroad (24.3%) including over 23.0% from the former USSR played the most important role in creating a new population structure (Rydz 1979). One of crucial factors influencing evolutions of population’s patterns in basic population structures are migrations. Migrations seem to confirm spatial adjustment abilities of population to constantly evolving social and economic conditions. A fast pace of a demographic development in Central Pomerania was an effect of a fast rise in the urban population (Tab. 1). An incredible role in developing processes have played industrialization that improved accommodation conditions and generated a shift of population from rural to urban districts. However between 1988-2002 a crucial role in the process of the dynamics’ evolution played social and economic transformations. A source of those unfavorable transformations (Fig. 1) should be considered in evolving social and economic situation of population. It makes young people migrate to other cities of Poland or other countries of the European Union such as Germany, the Great Britain, Ireland. According to the research the majority of the communities are characterized by a regressive type of demographic abilities (Fig. 2). A spatial concentration of the urban population is characteristic to a band-junction structure (Fig. 3). The biggest and best developed cities play a role of junctions in a settlement structure e.g. Koszalin, Słupsk, Lębork and Szczecinek. The present article also concentrates on factors influencing evolutions of population’ natural movements. The scientists recorded a tendency to limit a number of births in central Pomerania (Tab. 3 and Fig. 5). In a period of transformations they also recorded egression processes of the rural population.
