Deep and multi-level economic transformations that occurred in the cities and rural areas caused profound changes in the demographic structures. The problems connected with the issue of the demographic transformations in the cities, especially those big ones, such as agglomerations or metropolises, have remained a subject of numerous geographic, demographic or sociologic studies in the post-war period. It was a result of a high concentration of population in the analyzed units, their economic position and the role they played in the settlement network of a country. The main purpose of the present paper is to define the general mechanisms of social, demographic and settlement transformations in the coastal agglomerations, being developed and influenced by various factors influencing development patterns of their inner zones. The author analyzed the changes of demographic and social structures recorded between 1988 and 2006 and accommodation resources. Analyzing the changes of population patterns by their inner spatial structure, the author discovered an increasing number of inhabitants recorded in each zone, however generally more dynamic development patterns characterized the urbanized zones (Fig. 1). The author also recorded considerable changes of accommodation resources increase concerning their general and ownership structure during the analyzed period (1988-2006). Estimation of demographic transformation factors including concepts of natural increase and migration rate is considered an essential element in conducting the research on population dynamics (Fig. 3 and Fig. 4). The observed tendencies of population’s structures were also recorded in economic groups (population in pre-production, production and post-production age). Generally the author observes a significant increase of people in production and post-production age. The number of children and teenagers under 18 has considerably decreased – pre-production group (Fig. 5).
