nettomigraation

Net migration refers to the difference between the number of immigrants entering a country and the number of emigrants leaving that country during a specific period. It is a key component of population change, alongside natural increase (births minus deaths). A positive net migration figure indicates that more people are entering a country than leaving, leading to population growth. Conversely, a negative net migration figure means more people are emigrating than immigrating, resulting in population decline.

Net migration rates are often expressed as a percentage of the total population. This allows for comparisons between countries or regions of different sizes. Factors influencing net migration are diverse and can include economic opportunities, political stability, social conditions, environmental factors, and family reunification. Government policies related to immigration and emigration also play a significant role.

Understanding net migration is crucial for demographic analysis, economic planning, and social policy development. It helps policymakers forecast future population trends, assess the impact of migration on labor markets, and manage public services. Data on net migration is typically collected through censuses, population registers, and immigration/emigration surveys.
