Taking a closer look at the
2011 population statistics, there are some interesting changes in the population number development. To make thing easier to compare with the previous years, I have added the population of Bueng Kan back into Nong Khai, as otherwise Nong Khai would be biggest population looser by far - minus 44% compared with 2010.
Thus comparing 2010 with 2011, the biggest winner is Pathum Thani, which grew by 2.56% (25,255 citizen), closely followed by Phuket which grew by 2.54% (8,780 citizen). The biggest looser was Lampang, which lost 0.58% (4,415 citizen). However, in the top ten of provinces by population, there was no change this time.
1. | Krung Thep Maha Nakhon | 5,674,843 |
2. | Nakhon Ratchasima | 2,585,325 |
3. | Ubon Ratchathani | 1,816,057 |
4. | Khon Kaen | 1,766,066 |
5. | Chiang Mai | 1,646,144 |
6. | Buri Ram | 1,559,085 |
7. | Udon Thani | 1,548,107 |
8. | Nakhon Si Thammarat | 1,526,071 |
9. | Si Sa Ket | 1,452,203 |
10. | Surin | 1,380,399 |
Much more interesting trends show up when comparing the 2011 data with those from 1993, the earliest date for which DOPA has the detailed data online. Three provinces gained population by more than 50%, and these are also the same three which had the highest growth between 2010 and 2011. As the overall population also grew by 9.84%, those provinces which lost population didn't loose as much, but still four provinces lost more than 5% of their population in the last 20 years.
1. | Pathum Thani | 102.14% |
2. | Phuket | 82.23% |
3. | Nonthaburi | 56.48% |
73. | Lampang | -5.05% |
74. | Samut Songkhram | -5.78% |
75. | Phrae | -6.61% |
76. | Phichit | -6.82% |
Whereas the population of Bangkok stayed almost stable - an increase of just 1.83% (102,131 citizen) since 1993 - the two provinces north of Bangkok grew significantly. But looking at the geography, this is easily understood - south of Bangkok is just the already densely populated Samut Prakan province, both the east and the west of Bangkok are still not that densely populated, but to the north Nonthaburi adjoins densely populated districts of Bangkok directly.
If anyone wants to play around more with the numbers, I have
uploaded an Excel sheet with all the population data from 1993 to 2011 at province level.
