July 29 (UPI) -- Panama, Mexico and Costa Rica have emerged as leading destinations for U.S. retirees this year, offering a more affordable, safer and more comfortable lifestyle overseas, according to the 2025 Global Retirement Index prepared by International Living magazine.

The rising global population over age 65 -- projected to reach 16% by 2050, according to Statista -- is driving a wave of retiree migration focused on mild climates, access to quality healthcare and an active lifestyle with lower financial strain.

Data from the Social Security Administration show that more than 730,000 U.S. retirees receive their benefits while living abroad, with Latin America accounting for a growing share.

The cost of living there for a couple starts at about$2,400 per month. The country also offers 18-month temporary residency through a remote work visa.

Mexico ranks fourth, driven by its low cost of living, cultural diversity and affordable healthcare. According to the report, a retiree can live comfortably on about $1,500 a month. In tourist areas such as the Riviera Maya, monthly rent averages around $500.
