According to data released on the official website of the Department of Provincial Administration's Registration Bureau of Thailand's Ministry of Interior, the nationwide registered newborn population in 2025 totals 416,574 people, including 215,035 males and 201,539 females.
According to Thai Headline News Agency's report on the 9th, the data shows that Thailand's newborn population in 2025 is at its lowest level in 75 years and marks the second consecutive year that the number has fallen below 500,000. In 1950, Thailand's newborn population stood at 525,800, after which it steadily rose, surpassing one million for the first time in 1963 with 1,020,051 newborns. During the period from 1963 to 1983, the annual number of newborns remained above one million, peaking at a historical high of 1,221,228 in 1971. Since 1984, the number once again dipped below one million and gradually declined to 900,000, 800,000, 700,000, 600,000, and eventually 500,000. The year 2024 was the first time that the newborn population dropped below 500,000.
In 2025, the total number of deaths in Thailand is projected at 559,684 people, including 317,868 males and 241,816 females, marking the fifth consecutive year that deaths outnumber births.
Data shows that the average life expectancy of Thais is 77.4 years; the healthy life expectancy, defined as the number of years lived without chronic disease or disability and in good health, is 67.3 years. This means that, on average, Thais spend about 10 years in old age in a poorer state of health.
Projections indicate that by the year 2050, the average life expectancy in Thailand will rise to 81.6 years, and healthy life expectancy will reach 69.9 years. The gap between the two is expected to widen to 11.7 years. This reflects that while population longevity is increasing, the number of years spent in poor health is also extending, highlighting the necessity of strengthening disease prevention and promoting healthy aging policies.
