Thailand passed its population peak 4 years ago in 2022, and has since declined by 0.2%. The sex ratio of 95 males per 100 females is notably lower than the global average of ~101. The population is aging rapidly—median age will rise from 40 in 2026 to 49 by 2050. UN projections show a decline to 45.6M by 2100.
