Study title: Balances of the state and structure of the population by demographic characteristics
The purpose of the research is to provide information on changes in the population number and basic structures (gender, age, territorial distribution) due to the need to observe the pace and directions of development of selected population groups in connection with changes in the education system, labor market, or population aging. Data on the number and structure of Poland's population representing the state at a specific moment in the spatial system are among the basic statistical information to which many other social and economic life data relate, e.g., population income, consumption, production, effects of housing economy, infrastructure, medical services, level of education.
