Northern Ireland Sees Sharp Drop in International Migration as Population Growth Slows

BELFAST — The number of people moving to Northern Ireland from overseas fell sharply in 2025, with new official figures showing a significant decline in international migration and a much smaller increase in the region’s population.

An estimated 12,100 people arrived in Northern Ireland from outside the UK during the year, while about 10,200 people left. That resulted in a net international migration gain of approximately 1,900 people.

The figure represents the lowest level of net international immigration recorded in more than a decade, excluding the exceptional circumstances of the coronavirus pandemic in 2020.

The latest figures mark a substantial change from recent years, when Northern Ireland experienced a much stronger increase in migration. Net international immigration reached almost 9,000 people in 2023 before falling considerably over the following two years.

The decline reflects a broader pattern across the United Kingdom. International migration increased sharply in the period following the pandemic, but official estimates have subsequently shown a significant reduction in the number of people arriving from overseas.

When movements between Northern Ireland and other parts of the UK are also taken into account, the region recorded overall net emigration of about 800 people in 2025. This means more people left Northern Ireland for other parts of the UK or overseas than arrived from those locations combined.

Despite the migration decline, Northern Ireland’s population still increased slightly during the year.

The population grew by approximately 600 people in 2025, largely because births continued to outnumber deaths. There were around 1,400 more births than deaths during the year, partially offsetting the loss resulting from migration.

The figures indicate that natural population growth is currently helping to prevent an overall decline in Northern Ireland’s population. However, with migration falling and the gap between births and deaths relatively small, demographic pressures are becoming increasingly significant.

If current trends continue, Northern Ireland could begin experiencing an overall population decline in the near future.

The changing migration pattern could have wider implications for the region’s economy and public services. International migration has contributed to population growth in recent years and has also played a role in supplying workers to sectors facing labour shortages.

A sustained reduction in migration could therefore affect the size and composition of the workforce, while changes in the number of births and deaths could also increase pressure on services as the population structure evolves.

The latest figures provide an early indication of a potentially important demographic shift. While Northern Ireland’s population continued to grow in 2025, the increase was extremely small compared with the growth recorded during periods of stronger international migration.

The coming years will show whether the sharp fall in migration represents a temporary change or the beginning of a longer term trend that could eventually lead to population decline.
