Finland population growth slowed in 2025, reaching a total of 5,652,881 by the end of the year, with an increase of just 16,910 people, according to Statistics Finland. This represents almost half the growth seen in 2024 and signals a shift after two years of unusually strong gains fueled by migration.
The surge in population during 2023 and 2024 was largely linked to arrivals from Ukraine following Russia’s invasion. This temporarily accelerated Finland’s overall growth. In 2025, migration flows began to stabilize, leading to a slower annual increase and a return to a more typical growth rate.
Despite the slowdown, Finland’s population continues to expand, maintaining a long-term upward trajectory. The recent changes highlight how international events can shape domestic demographics in a short period.
Population shifts were uneven across the country. Seventy-seven municipalities saw population growth, while 227 experienced declines. Urban regions, particularly Uusimaa where Helsinki is located, remain magnets for newcomers. In this region, one in five residents now has a foreign background, reflecting both continued migration and the concentration of immigrants in major cities.
The number of Finland-born residents with a foreign background, often called second-generation residents, has now exceeded 100,000. This milestone underscores the long-term demographic impact of earlier migration and highlights the growing diversity of Finland’s youth population, especially in metropolitan areas.
Data from Statistics Finland also shows changes in religious affiliation. More than two million people now report no connection to a religious community, indicating ongoing cultural shifts in Finnish society and a decline in traditional religious participation.
Migration remains the main driver of population growth in Finland, as the country continues to face low birth rates and an ageing population. This dynamic has implications for public services, social planning, and labor markets over the coming decades.
The slowdown in 2025 follows two years of rapid demographic change driven by global events. Analysts predict that population growth will remain moderate, with urban areas continuing to attract the majority of newcomers, while smaller towns and rural municipalities face declining or stagnant populations. The evolving demographic patterns highlight the need for targeted regional planning and policy adaptation.
