Chart and table of population level and growth rate for the Bangkok, Thailand metro area from 1950 to 2025.

In 2024, the number of inhabitants in the Bangkok Metropolitan Area, Thailand, was estimated to amount to around **** 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.

Manila, die Hauptstadt der Philippinen, ist im Jahr 2022 mit geschätzt rund 14,4 Millionen Einwohner:innen die größte Stadt in Südostasien und in den Mitgliedstaaten von ASEAN. Die Hauptstadt von Indonesien, Jakarta, ist mit etwa 11,1 Millionen Einwohner:innen die zweitgrößte Stadt der Region, vor Bangkok mit etwa 10,9 Millionen Einwohner:innen im Jahr 2022.

Die Statistik zeigt die zehn größten Städte in den ASEAN Mitgliedstaaten im Jahr 2022. ASEAN (Association of Southeast Asian Nations) ist ein Staatenverbund der südostasiatischen Nationen Brunei, Kambodscha, Indonesien, Malaysia, Myanmar, Philippinen, Singapur, Thailand und Vietnam. Das Ziel der Organisation ist es wirtschaftliche Zusammenarbeit in Südostasien zu fördern und politische Stabilität zu sichern.

Mit knapp 5,7 Millionen Einwohnern war Krung Thep (Bangkok) im Jahr 2019 die größte Stadt in Thailand. Auf die gesamte Metropolregion Bangkok kommen laut der Quelle etwa 10,9 Millionen Einwohner. Thailand hatte im Jahr 2019 eine Gesamtbevölkerung von 69,6 Millionen Einwohnern.

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.
