Thailand Population 2020 (Live)

69,800,451

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.

The current population of Thailand is 69,800,451, based on projections of the latest United Nations data. The UN estimates the July 1, 2020 population at 69,799,978.

Thailand Area and Population Density

Thailand is the 51st largest country on earth in terms of total area, but 21st in terms of population. Thailand is 88th in terms of population density, with 132.1 people per square kilometer (342/square mile), based on the 2011 population figures.

Largest Cities in Thailand

While the country's population is spread fairly well, a substantial amount of people live in Bangkok and the surrounding Bangkok Metropolitan Region. Bangkok, located in Central Thailand, has a population of more than 9 million, or close to 13% of the country's population. More than 14 million (or 22.2% of the total population) live in the Bangkok Metropolitan Region. This means Bangkok is much larger than any other urban areas in Thailand.
