Portugal's Q1 Newborn Screenings Reach a Ten-Year Peak — INSA Processes 21,813 Heel-Prick Tests in January–March, More Than a Thousand Above Last Year
The Instituto Nacional de Saúde Dr. Ricardo Jorge says 21,813 newborns were screened under the national heel-prick programme in Q1 2026 — the highest first-quarter figure in ten years, up 5% on Q1 2025 and topping the 21,065 recorded in Q1 2023.
Portugal's first-quarter newborn screenings hit a decade high in 2026. The Instituto Nacional de Saúde Doutor Ricardo Jorge (INSA), which coordinates the National Neonatal Screening Programme, reported on Tuesday 22 April that 21,813 newborns were processed through the famous teste do pezinho — the heel-prick test — between 1 January and 31 March. It is the highest first-quarter figure in at least ten years, exceeding the 21,065 recorded in Q1 2023, the 20,575 recorded in Q1 2024, and the 20,782 recorded in Q1 2025.
Why the heel-prick number is the cleanest demographic signal
In Portugal, coverage of the national newborn-screening programme is near universal. Under the national health service, every baby born in a Portuguese maternity ward — public or private — is screened by heel-prick between the third and sixth day of life. INSA's monthly tallies are therefore, in practical terms, a real-time census of births: the number of heel-prick samples received and analysed each month tracks the number of live births with a lag of only a few days.
That makes INSA's quarterly release the fastest reliable demographic indicator in the country, arriving roughly three months earlier than the civil-registry birth data published by the Instituto Nacional de Estatística. Journalists, demographers and fertility economists watch the INSA release because it tells them what is actually happening to Portuguese births before the official statistics catch up.
The monthly pattern
Using the distribution from Q1 2025 (January 7,670; February 6,371; March 6,741) as a template, INSA's Q1 2026 total of 21,813 implies continued strength across all three months and a stronger January than last year. That matters because January is consistently the highest-birth month in the Portuguese calendar — births conceived during the spring and early-summer tourism season — and a rising January figure has historically predicted stronger full-year totals.
The number also reverses the brief dip recorded in 2024, when the Q1 figure fell to 20,575 after climbing continuously since 2022. On that trajectory, Portugal's full-year 2026 live-birth total is on track to clear 85,000 — still well below the roughly 100,000 annual births needed to stabilise the population without net immigration, but the strongest showing since the mid-2010s.
What drives the uptick
Three factors are usually cited when Portuguese fertility moves. First, the expanding foreign-born population: Portugal has added more than 700,000 residents since 2017, many of them young adults of childbearing age from Brazil, India, Nepal and Angola, whose fertility rates sit above the native-born average. Second, the family-policy package: Abono de Família reforms, the 28-day exclusive paternity leave, and the 150-day shared parental leave — all covered in our guide published yesterday — have been credited with lifting the birth planning calculus for younger couples. Third, the labour market: youth unemployment is still elevated but has fallen steadily since 2023, and real wages ticked into positive territory in the second half of 2025.
Why it matters beyond the headline
Portugal's demographic ledger ended 2025 with a net population loss of 34,244 — deaths exceeding births — despite more than 88,000 registered live births. The INSA Q1 2026 number suggests that 2026 will narrow the gap but not close it: even at 85,000-plus annual births, the crude death rate from an ageing population will still push the natural balance negative. Net migration has been doing the demographic work since 2017, and the INSA release is a reminder that it will keep doing it.
For policy, the number is politically useful: the Montenegro government has staked significant political capital on the family package, and a decade-high first quarter is the sort of headline that translates readily into a press conference. It is also a rebuke to the Chega narrative that Portugal's birth story is one of decline — the actual first-quarter data are moving in the other direction. Expect the figure to reappear in Ministry of Health talking points within the week.
