In 1800, the population of the territory that makes up present-day Thailand was approximately 4.7 million people. As part of the kingdom of Siam, the population of Thailand would grow gradually through the 19 th century, with much of the population growth being driven by Chinese emigration from southern Qing China into Siam, in search of work and refuge from instability in their home country. This migrant influx would continue throughout the century, with estimates suggesting that the Chinese population in Siam grew from 230,000 in 1825, to over 792,000 in 1910; by 1932, over 12 percent of the population in modern-day Thailand was ethnically Chinese. Migration from China would see another surge under the reign of Vajiravudh, as the "Warlord era" in China, after the fall of the Qing dynasty, would see entire families of Chinese immigrants arriving in Thailand. While immigration would slow in later years, Chinese-Thai would remain a significant demographic in Thailand’s population, both as one of the largest overseas Chinese populations, and accounting for an estimated 11-14 percent of the total Thailand population in 2012.

Population growth would slow somewhat in the 1930s, as several rebellions and coups, paired with a rise in anti-Chinese sentiment in the country, would result in a sharp decline in immigration to the country. In the years following the Second World War, the population of Thailand would begin to grow rapidly, following a wave of urbanization and a significant increase in standard of living throughout the country. As a result, the population of Thailand would rise from approximately 20 million in 1950, to just under 63 million by the turn of the century just 50 years later. This population growth would slow somewhat as the country would continue to modernize in the 2000s, and in 2020, it is estimated that just under 70 million people live in Thailand.

As of March 2024, the population of those who were no older than 15 years old in Thailand amounted to approximately 11.04 million, which was the highest compared to other age groups. The next largest age group was between the ages of 46 and 55, with a total of around 10.24 million people.  Population development in Thailand Thailand is the fourth most populated country among all ASEAN (Association of South-East Asian Nations) member countries. The recent total population in the country stood at around 70 million. While the total population number is expected to increase, the number of children in Thailand has decreased over the years. Thailand’s aging society   Thailand is one of the fastest-aging countries in the world. As of January 2023, the proportion of senior citizens in Thailand stood at 18 percent. The elderly population in the country is predicted to continue growing steadily in the future. Therefore, ASEAN established the ASEAN Centre for Active Aging and Innovation (ACAI) in 2018 under the leadership of Thailand. ACAI aims to promote healthy aging and enhance the lifelong quality of aging in Thailand and other ASEAN countries.

In 2023, there were around 14.87 million females in Thailand who were 25 to 54 years old, which was the largest population group compared to other female age groups. In comparison, there were almost four million females who were 15 to 24 years old in that same year.

In 2022, there were more than 3.5 million people aged between 15 and 59 years registered in Bangkok, the capital of Thailand. Approximately 1.2 million adults aged 60 years and older were officially registered that same year.

Sampling procedure

MICRODATA SOURCE: National Statistical Office

SAMPLE DESIGN: A stratified two-stage sample was adopted. 5 strata were Bangkok and the four regions (Central, North, Northeastern, South), and each stratum was divided into municipal areas and non-municipal areas. Then, the sample was selected in two stages. In stage one, a number of sample enumeration districts (EDs) were selected systematically in each sub-stratum with sampling fraction of 1 in 20. In stage two, a sample of households was selected systematically from each sample ED as follows. For private households, one-fifth of households in each ED were selected. For collective households, one-fifth of special households and one fiftth of institutional households were selected in each sub-stratum (municipal and non-municipal areas.

The population was enumerated with Form 2, which consists of three parts. Part 1 identifies the location of the household. Part 2 contains questions on population including questions on demography (S1-S16) and questions on detail of population (L17-L27). Part 3 contains housing questions that are asked of the sample private households only. Note: (i) Only Part 1 and questions on demography (S1-S16) of Part 2 in Form 2 were asked of the private households that have not been selected as sample households. (ii) For the private households that have been selected as sample private households (20%), all questions in Form 2 were asked. (iii) All collective households were enumerated using Form 2 on Part 1 (location of household) and Part 2 (questions on demography and on details of population), but questions on housing were not asked.

The Thai Demographic and Health Survey (TDHS) was a nationally representative sample survey conducted from March through June 1988 to collect data on fertility, family planning, and child and maternal health. A total of 9,045 households and 6,775 ever-married women aged 15 to 49 were interviewed. Thai Demographic and Health Survey (TDHS) is carried out by the Institute of Population Studies (IPS) of Chulalongkorn University with the financial support from USAID through the Institute for Resource Development (IRD) at Westinghouse. The Institute of Population Studies was responsible for the overall implementation of the survey including sample design, preparation of field work, data collection and processing, and analysis of data. IPS has made available its personnel and office facilities to the project throughout the project duration. It serves as the headquarters for the survey. The Thai Demographic and Health Survey (TDHS) was undertaken for the main purpose of providing data concerning fertility, family planning and maternal and child health to program managers and policy makers to facilitate their evaluation and planning of programs, and to population and health researchers to assist in their efforts to document and analyze the demographic and health situation. It is intended to provide information both on topics for which comparable data is not available from previous nationally representative surveys as well as to update trends with respect to a number of indicators available from previous surveys, in particular the Longitudinal Study of Social Economic and Demographic Change in 1969-73, the Survey of Fertility in Thailand in 1975, the National Survey of Family Planning Practices, Fertility and Mortality in 1979, and the three Contraceptive Prevalence Surveys in 1978/79, 1981 and 1984.

In 2024, the number of inhabitants in the Bangkok Metropolitan Area, Thailand, was estimated to amount to around 11.2 million people. The figures show a gradual increase in Bangkok's population in the last 10 years. Bangkok’s most populated and most popular areas Bangkok experienced rapid growth between the 1960s and 1980s and has developed into one of Southeast Asia's leading commercial markets, a hub for real estate, retail, manufacturing, commerce, transportation, and financial services, despite challenges and political instability over the last decades. Khlong Sam Wa, Sai Mai, and Bang Khae, located on the outskirts, are the most populated districts in Bangkok, with comparatively low rental prices. In contrast, rather expensive areas around Wireless Road, upper and lower Sukhumvit, Sathorn, and Silom are particularly sought after by high-income residents and working expatriates. Bangkok’s housing prices Local buyers are facing difficulties as a result of Bangkok's increasing interest rates, which have reduced house affordability, as well as a lack of confidence in the economy. The price index of townhouses in Bangkok has shown increases since 2013. The same goes for single-detached houses and condominiums. Long-term demand will be limited by Thailand's aging population, and many prospective new purchasers, particularly Millennials and Gen Y, often choose to rent instead of buying.
