Bangkok has been rapidly growing and expanding for the last few decades which has created a very unique and attractive city. And despite the millions being added to the city's population each year a surprisingly high percentage are living in suburbs rather than actual urban Bangkok.
Since 2000, the Bangkok region has experienced annual population growth 2.5 times the rate of growth from 1980 to 2000. By 2010, the Bangkok region – which includes the provincial level city of Bangkok and the provinces of Samat Prakan, Samut Sakhon, Pathum Thani, Nonthaburi and Nakhon Pathom – was nearing a population of 15 million (Note 1).
As is characteristic of urbanization in both developing and developed countries, much of Bangkok's recent growth has occurred outside the city, in suburban (and exurban) areas. Between 2000 and 2010, the city grew by 30%, while the suburban provinces grew more than twice as quickly, at 66%. The city's population growth was 1.9 million, while the suburban provinces added 2.5 million population (Figure 1).
