According to current projections, Thailand’s population will reach its peak in 2028 at 70.4 million people. The current annual population growth rate is 0.25%.
As countries become more developed, it’s common to see a decline in fertility rates and an increase in the aging population. Thailand experienced this transition very quickly between 1970 and 1990 when the fertility rate dropped from 6 births per woman to 2 births per woman.
Fertility rates in Thailand are about 1.5 births per woman, about 30% under the population replacement rate of 2.1 births per woman. The fertility rates have been this low for several years; however, population momentum has still resulted in population growth although the population is expected to decline following 2028.
Thailand Population Growth
Until very recently, the population numbers were growing at a far greater rate, but it’s claimed that the government-funded family planning program has raised awareness and led to a dramatic fall in birth figures. In 1960, the population growth was at its height with figures of around 3.1% but this has fallen to around 0.34% today.
Thailand Population Projections
The growth of the past has significantly slowed in the recent past and is expected to begin a slight decline by 2030.
The population is projected to remain fairly constant around 69 million until 2035, but will eventually decrease to 65 million by 2050.
