# Migration swung 17,000 people in two years. The island felt both.

Puerto Rico's net migration flipped from a gain of 14,425 in 2024 to a loss of 2,779 in 2025 - and the municipio-level numbers show where the pressure landed.

Puerto Rico's net migration turned negative again between July 1, 2024 and June 30, 2025, recording -2,779 for the period [^5]. That reversal is steep. The prior year had posted a positive net migration of 14,425 - a swing of more than 17,000 people in a single annual comparison [^6]. In 2024, that positive migration had helped stabilize the population [^7]. That stabilization is now gone.

The municipio data from 2023 shows the split that persists underneath the island-wide number. Forty-six of Puerto Rico's 78 municipios - 59.0% - posted positive net migration that year [^2]. Guaynabo (495 net arrivals), Bayamón (389) and Isabela (305) led the gainers [^3]. Ponce lost the most, 1,050 net people, followed by Toa Baja (375) and Guayama (289) [^4]. The island does not move as one body. Some places are receiving. Some places are emptying.

Act 60, implemented in July 2019, requires individuals to become bona fide residents and spend at least 183 days per year on the island [^8]. That rule means every decree holder who actually meets it is a person living here, spending here, counted here. The read here is that even a modest flow of decree holders who stay and comply adds bodies to the positive-migration municipios - but the aggregate number for 2024-2025 suggests that flow did not offset the broader departure trend.

This column has argued before that declining population is not a background condition - it is the central risk. The documents Puerto Rico's own creditors file name it plainly: declining population and outmigration are listed as risk factors for the island's outlook [^9][^1]. The 2025 figure is not a surprise. It is the trend reasserting itself after one year of relief, and Ponce's 1,050-person net loss in a single prior year is the kind of number that does not fix itself.
