Eurostat regional population projections: Belgium bucks EU decline as migration drives local growth
Eurostat regional population projections show the EU peaking at 453.3M in 2029 before falling to 445M by 2050, with Belgium’s gains driven largely by net migration.
Europe’s statistical office, Eurostat, has released regional population projections for 2025–2050 that forecast a shifting demographic map across the European Union. The new Eurostat regional population projections indicate the overall EU population will briefly rise to 453.3 million in 2029 before edging down to about 445 million by 2050. While the bloc as a whole faces long-term decline in many areas, Belgium stands out as an exception where positive net migration offsets falling natural change in most regions.
EU population outlook to 2050
Eurostat projects that seven out of every ten regions in the EU will record population losses by 2050, driven primarily by a sustained negative natural change. The aggregate EU population is expected to rise slightly until 2029 then decline, altering the balance of population across member states. These shifts are projected to affect public finances, service demand and political representation in coming decades.
Deaths now outnumber births across most regions
Historical Eurostat data shows deaths have exceeded births in the EU since 2012, and the new projections foresee that pattern continuing through the 2040s. By 2050 only a small fraction of regions — roughly 1.8% — are expected to register a positive natural change where births outnumber deaths. The regions with positive natural change are concentrated in a handful of western member states, underscoring an east–west demographic divide.
Belgium bucking the trend with migration-led gains
Belgium is highlighted in the projections as one of the few countries where most regions avoid long-term population decline. Net migration is expected to be the principal engine of growth in 41 of Belgium’s 44 regions, according to the Eurostat scenarios. Even where natural change falters, international inflows for work, study, family reunification and asylum are projected to sustain overall increases in population for much of Belgium.
Belgian demographers point to the country’s economic and institutional attractiveness as the key factor behind sustained migration gains. Patrick Deboosere, a population specialist at the Free University of Brussels, notes that Belgium has remained a magnet for migrants from across Europe and beyond, with past annual net increases estimated between about 35,000 and 50,000 people. Eurostat’s projections, however, suggest migration pressures may ease later in the period, and some Belgian areas — notably small municipalities — may still see slight declines.
Capitals and metropolitan areas concentrate growth
Eurostat underlines that capital-region dynamics will be central to future population patterns, with about 90% of capital regions expected to grow faster than their national averages. Large cities and their metropolitan zones are forecast to remain the primary destinations for newcomers, even as rural and peripheral areas shrink. This concentration creates planning challenges for urban infrastructure, housing and public services while reinforcing divergence with lagging regions.
Regional divergence: eastern shrinkage and western gains
The new projections reveal stark geographic contrasts: many regions along the EU’s eastern external border are likely to face continuous population loss through 2050. More than 80% of regions in countries such as Greece, the Czech Republic, Croatia and Portugal are also forecast to decline due to negative natural change. Conversely, western member states — where positive net migration offsets low fertility — are expected to retain or grow their populations, deepening regional disparities.
Implications for budgets, services and representation
Shifting population totals and regional imbalances carry immediate policy consequences. Falling populations in large parts of the bloc will reduce local tax bases and increase per-capita costs for maintaining health, social care and transport networks. At the EU level, demographic change will factor into debates over cohesion funding, labour markets and the apportionment of seats in pan-European bodies as long-term population trends alter relative weight between member states.
Policymakers will also confront choices about migration policy, housing investment and incentives to raise fertility or retain younger cohorts. The Eurostat regional population projections make clear that, for many regions, migration will be the decisive variable shaping demographic futures and the capacity to sustain local economies and public services.
The Eurostat projections mark a call to action for regional and national planners to adapt to diverging demographic trajectories, balancing investment in growing metropolitan centres with targeted support for shrinking areas.
