Modern Bangkok has undergone explosive growth since from 1960, expansion has sprawled outward well beyond the administrative boundaries into the surrounding agricultural areas. Most of the border districts has become residential and industrial where inner city area are accommodated with institutional and commercial activities.

Bangkok was formerly divided into two municipalities, The Krung Thep on the east bank and Thon Buri on the west, which is connected by several bridges. In 1971 the two regions were united as a city and province administered with a single municipal government. In 1972 the city and the two surrounding provinces were merged into one province, called Krung Thep Maha Nakhon currently called Bangkok Metropolis.

Bangkok's Population until 1909, There are no reliable population statistics for Bangkok (or Siam as a whole) prior to the 1920s. Though there are some relevant data in the National Archives, for example labour registrations and tax collection records, all these are scant and difficult to interpret and compare. Estimates of Bangkok's population between the mid-19th century and 1909 also vary widely.

Table below is the estimates of Bangkok's Population during 1856-1909

In Bangkok before 1892, no provincial administration was established. Many settlements in Bangkok prior were on water. Numerous floating houses or shops were located along the banks and waterways of the Chaophraya river and the various canals.

The settlements in Bangkok prior to 1880 as per Askew, The first land-based settlements clustered along waterways near the wat (temple) which served religious, educational and recreational functions. These "Bang' which may be translated as "water hamlet" settlements formed a loose network.

While the great mass of the urban population continued to live on the water until at least the close of Rama IV's reign, the movement onto land was pioneered by the nobility building palaces and the establishment of temples. After 1855 European traders settled along the southern reaches of the river and were soon occupying houses and shops on land. More important to the ecology of the emerging land-based city than the jarang (westerners), however, were various distinctive ethnic and occupational communities. The ethnic mosaic which comprised settlement groups such as the Chinese at Sampeng, the Indians of Pahurat, the Vietnamese of Wat Yuan, the Khmer of Samsen spread in a loose pattern of "Yarn" (districts) around the city wall. The clustering ofBang and Ban (villages) was the earliest pattern of settlement.

The wide range of population estimates was affected by fluctuations in the number of Chinese migrants. The Chinese constituted a substantial component of the entire Bangkok's population prior to 1950, and Chinese migrants, mainly males, would typically live in Thailand for a few years and return home after they accumulated enough wealth. It was therefore difficult to assess their numbers accurately.

Bangkok History

Bangkok grew slowly through the 18th and early 19th centuries, despite being the capital since 1782. In 1822, the population was estimated at 50,000 or less. The population began to grow as the city became more modern in the 19th century, with faster growth in the 1930s after the discovery of antibiotics improved healthcare.

Although founded as late as 1782, According to Kyoto-Seas, Bangkok was soon established as the country's leading urban centre. Of course, the emergence of a clearly identifiable geographically delineated, country of Siam was a slow progress. But even though we cannot strictly speak of a nation in early 19th century Siam, it is clear that by around 1820, Bangkok surpassed other Thai-speaking centres in terms of size and commercial significance.

According to Terwiel and Sternstein, in 1827 other urban centres were much smaller than Bangkok. Ayutthaya contained 41,350 people (26,200 according to a 1849 later estimate), Chantaburi 36,900, Saraburi 14,320 and Phitsanulok 5,000. Bangkok was a royal city, main religious centre, and port of international trade. As such it drew goods and people from the countryside and also brought an influx of migrants (mostly Chinese).

The major changes came only from about the 1880s and 1890s, with a marked acceleration of population growth (much of it caused by Chinese migration) and an expansion of permanent land dwelling. As long as the area of Bangkok was confined, and the population is small, city regulation could be maintained within the traditional Siamese social structures. Thailand was an absolute monarchy until 1932, The linking Bangkok administrative structure with royal interests produced both a physical and economic stamp on Bangkok which has had an enduring effect on Bangkok's development.

The first population census in 1909 to 1910 does not include a figure for metropolitan Bangkok, but estimates show that the population is between 400,000 to 500,000. The 1919 census counted 478,994 in Bangkok-Thonburi of which 337,236 lived in Changwat Pranakorn (province) and 141,758 in Changwat Thonburi. The 1919 Bangkok distribution by ethnic groups was: 225,729 are Thai's, 116,431 are Chinese, 14,193 are Indians, 1,447 are Europeans and U. S. A.,716 are Vietnamese, 523 are Cambodian, 511 are Burmese, 232 are Japanese.
