Mexico registered 1,678,532 births in 2025, according to figures INEGI published on 25 Sep 2026. That's 0.4% more than in 2024 and 26.8% fewer than in 2016, the earliest year in INEGI's 2025 report. Both comparisons are our arithmetic.
Births registered in Mexico, millions, 2016 to 2025
By year of registration, not year of birth
The registered birth rate was 47.7 per 1,000 women aged 15 to 49, the same as in 2024. Of the people registered in 2025, 78.5% were registered before their first birthday, and 11.3% were six or older.
A pause after a long fall
Registered births fell in every year from 2016 to 2025 except two. The sharpest drops came in 2020, when registrations fell 22.1% to 1.63 million, and in 2024, when they fell 8.2% to 1.67 million. In 2021, they rose 17.4% to 1.91 million. By our reading, INEGI's figures suggest the 2020 drop was largely a registration effect: only 63.2% of children born in 2020 were registered that same year, compared with about 72% to 73% in the years before.
The 2025 count halted the slide, but it's still the third-lowest since 2016, above only 2020 and 2024.
Registered isn't the same as born
INEGI counts births in the year they're registered, so each year's total mixes children born that year with late registrations from earlier years. Of the children born in 2024, 78.6% were registered in 2024 and 21.4% in 2025. For children born in 2016, 72.2% were registered in the same year. So a change in how quickly families register can move the totals, apart from any change in the number of children born.
Where and to whom
The rate varies widely by state. Baja California (86.6 per 1,000 women aged 15 to 49), Chiapas (83.9) and Durango (61.0) had the highest, and Mexico City (31.1) had the lowest. Mothers aged 20 to 24 accounted for 22.3% of the births registered in 2025, and mothers aged 25 to 29 for 21.9%. In 2025, 85,357 births were registered to mothers aged 10 to 17.
INEGI publishes registered births once a year; the figures for 2026 are expected in 2027. The long record: why-mexico.com.
