The Yucatán Peninsula is experiencing significant demographic and public health shifts. Data from INEGI indicates a continuous four-year decline in the state of Yucatán’s birth rate, which fell to 35.9 births per 1,000 women of childbearing age in 2025. This represents a 17.7% decrease since 2021 and has contributed to an aging population, with the state’s median age rising from 30 to 32 between 2020 and 2025.

Parallel to the declining birth rate, the region has seen a sharp increase in maternal mortality. In 2026, reports from the Secretariat of Health indicated a 66% rise in deaths related to pregnancy, childbirth, or the postpartum period across the peninsula. Quintana Roo recorded the highest number of fatalities, accounting for approximately 53.3% of the regional total, followed by Yucatán and Campeche. Primary causes for these deaths include obstetric hemorrhages and hypertensive disorders such as preeclampsia.
