Portugal's Births Tick Up and Deaths Fall in Mid-2026, With Immigrant Mothers Holding the Line
Live births rose 0.8% in the first half of 2026 and July deaths fell 5.2%, but Portugal still records far more deaths than births. What keeps the birth line from falling further is immigration: foreign-resident mothers now account for roughly a third of the country's newborns.
Portugal's latest population figures, published on Friday by the national statistics office (Instituto Nacional de Estatística, INE), carry a modestly encouraging headline: more babies and fewer deaths. In the first half of 2026, live births rose 0.8% on the same period a year earlier. Deaths in July fell 5.2% from July 2025, to 9,403. Marriages in June jumped 8.5%, to 4,271.
Look past the monthly noise, though, and the deeper problem is unchanged. Portugal still buries far more people than it delivers. In June the natural balance — births minus deaths — was negative by 1,740, even if that was a shade better than the 1,854 deficit of June 2025. Births themselves remain low in absolute terms: 7,068 in June, down 2.4% on the year. The country's population is not shrinking through emigration so much as through arithmetic.
What has kept the birth line from sliding further is immigration. Portugal's 87,764 births in 2025, a 3.7% annual rise, were only possible because foreign-resident mothers now account for roughly a third of all newborns — a share that has doubled in a decade. In Greater Lisbon, half of all babies in 2025 were born to foreign mothers, and it was the only region in the country to post a positive natural balance. Strip out the contribution of the foreign-born, in other words, and the national decline would look considerably steeper.
That makes the summer's demographic data quietly relevant to the very readers of this publication. Foreign residents, who now make up 14% of the 11.4 million people living in Portugal, are not a footnote to the country's population story. Over the past ten years they have become its main engine of renewal — in the maternity wards as much as in the labour market.
Not every number points the same way. Observador reported alongside the release that deaths of infants under one year old rose in the first half of 2026 even as overall mortality fell — a counter-trend worth watching, though the monthly series is volatile (July recorded 26 infant deaths, the same as a year earlier) and the half-year total was not detailed in INE's public summary.
None of this resolves the structural bind. Portugal's fertility rate remains well below the level needed to hold the population steady without migration; its median age, at nearly 46, is among the oldest in Europe; and the strain that an ageing society puts on pensions and health care only deepens. A good month for births and a mild one for deaths is welcome news. But the mid-year tape is a reminder that the country's demographic future is being written, in large part, by the people who have chosen to move there — and by whether the state treats that fact as a temporary patch or a permanent feature.
