väestönlisäys

Väestönlisäys is a Finnish term that translates to population growth. It refers to the increase in the number of individuals in a population over a specific period. This growth is primarily determined by the balance between births and deaths, and can also be influenced by migration. When the birth rate exceeds the death rate, and there is a net positive migration, the population experiences growth. Conversely, if deaths outnumber births, or if there is significant emigration, the population may decrease.

Factors contributing to population growth are diverse. Improvements in healthcare, sanitation, and nutrition have historically led to lower death rates, allowing more people to survive and reproduce. Increased life expectancy also plays a role. Social and economic factors, such as higher fertility rates in certain regions or periods, can also drive population increases. Conversely, declining birth rates, increased mortality, and emigration can lead to population stagnation or decline. Understanding väestönlisäys is crucial for urban planning, resource management, and socioeconomic development, as it impacts various aspects of society.
