Portuguese Births Rebound to 87,764 in INE's 2025 Demographic Tape — Foreign-Born Mothers Carry Roughly a Third of the Recovery as Natural-Balance Deficit Widens to −34,053

Portugal recorded 87,764 live births in 2025 — up 3,122, or 3.7%, on 2024 — according to the latest Estatísticas Demográficas bulletin released by the Instituto Nacional de Estatística (INE, National Statistics Institute). The number marks a modest rebound from the 84,642 floor logged in 2024 (itself a 1.2% drop from 2023), but the underlying natural balance — births minus deaths — worsened to −34,053 in 2025 from −33,754 in 2024 as the death count outpaced the birth recovery. Roughly one in three of last year's babies was born to a mother of foreign nationality, underscoring how Portugal's demographic story is now overwhelmingly an immigration story.

The headline numbers

The 2025 print of 87,764 live births is the first year-on-year increase since 2021, but it remains well below the 89,000-plus prints registered before the pandemic-era trough and roughly 15% under the 2008 level. The Total Fertility Rate (TFR), which measures the average number of children per woman of childbearing age, sits at around 1.40 — flat against 2024 and well under the 2.1 replacement rate. Eurostat's bloc-wide TFR landed at 1.38 in 2024, so Portugal hovers a fraction above the EU floor but trails France (1.66) and Romania (1.81). The average age at first birth has crept up to roughly 31 — among the oldest in the European Union — and the share of births to mothers aged 35 or older now sits comfortably above 35%.

The natural-decline streak

Deaths have outnumbered births in Portugal every calendar year since 2009 — a 16-year streak with no realistic prospect of reversal under current fertility trajectories. The widening of the natural balance deficit to −34,053 in 2025 was driven entirely by mortality, not births: an ageing population structure and the lingering tail of cardiovascular and respiratory mortality among the over-75 cohort pushed deaths past 121,000 last year. The Portuguese population total — sitting just above 10.6 million — has been sustained, and at times grown, only because net migration has comfortably exceeded the natural-balance gap each year since 2018.

The immigration handle

The roughly one-in-three share of 2025 births attributable to foreign-born mothers — broadly stable on 2024 — explains why headline births rose even as the Portuguese-born cohort kept shrinking. Brazilian, Indian, Nepalese, Cape Verdean, Angolan and Bangladeshi communities account for the bulk of the foreign-born share. The implication for Portuguese demographics is structural: without sustained inward migration, the natural-balance gap projects out toward 50,000 a year by the early 2030s under INE's baseline trajectory, and the headline population total would slide back below 10 million inside a decade.

Why fertility lags

The drivers are well-rehearsed inside Portuguese demographic policy circles. Late entry into stable employment — average age at first stable contract has stretched past 28 — combines with Lisbon and Porto housing costs that have outrun real wages by a wide margin since 2016. Childcare capacity has lagged demand outside the major metropolitan areas, even as the Plano de Recuperação e Resiliência (PRR, Recovery and Resilience Plan) has financed an expansion of free crèche coverage for children up to three years of age. Female labour-force participation, at roughly 70%, is among the EU's highest, which structurally pushes first births later in the life cycle.

The pension math

The old-age dependency ratio — population aged 65-plus per 100 working-age — sits at roughly 38 in 2025 and is projected past 60 per 100 by 2050 under both INE and Eurostat baseline scenarios. The Sistema Previdencial pension system runs on contributions from the working-age cohort: even at constant replacement rates, the demographic structure pushes the pay-as-you-go arithmetic toward higher contribution rates, higher retirement ages, or transfers from general taxation by the mid-2030s. The Conselho das Finanças Públicas has flagged this trajectory in successive reports; the European Commission's June 2025 Ageing Report puts Portugal's public-pension expenditure rising 1.6 percentage points of GDP through 2050 — a milder slope than Spain or Italy, but still a meaningful fiscal weight.

The policy takeaway

Three levers move the demographic dial in any realistic timeframe: stable immigration pathways, affordable family-formation conditions in Lisbon and Porto, and childcare capacity for children under three. The 2025 print confirms that Portugal can keep the birth count rising in absolute terms — but only with the immigration handle pulled hard. Any tightening of the residence-authorisation regime under the sixth Lei dos Estrangeiros amendment cycle would feed directly through the births tape inside three years.
