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.

Yes, the data is based on the where each citizen has registered himself. Thus there are of course systematic errors due to those migrant workers from Isan who are still registered in their home village but live in Bangkok most of the time, but when comparing the data from different years these systematic errors should roughly cancel out. More close to the reality are the census data, which uses where one actually lived at the date of the census (and also includes the non-Thai residents) - but these are only done every ten years, and the data from 2010 is still not available online :-(
Is there any chance to get to actual number of people in a particular city. (More interested than cities than provinces). So not just by house registration, but also including migrants who move to a city without acquiring property (or otherwise registering as a resident) ?
This statistics by DOPA is based on the registration data, but it does include most of the municipalities (except some of the most recently former TAO) and goes down to the subdistrict level. As I said before, the census data is probably the one which is closer to reality, but still no sign of the data for the 2010 census. And for the 2000 census, at least the data available on the net did only go down to district level, separated between municipal and non-municipal population. But in case there is more than one municipality in one district, there's no way to get the two numbers separated.
Since you have alot of knowledge of the statistics of Thailand. Where would be a good place to find out the most population or the most densely populated tambon and amphoe in Thailand?
I don't know any other resource on the net which has that numbers. The Amphoe and Tambon with the highest population is still easy to get from that DOPA data with a little help of my software - Mueang Samut Prakan with 506997 citizen and Mueang Nakhon Ratchasima with 441309 are the most populous Amphoe. Hat Yai with 157161 and Nai Mueang (in Nakhon Ratchasima) with 138698 are the most populous Tambon. For population density can only give you the Amphoe, and right now only based on the 2000 census data. Pom Prap Sattru Phai with 45187/km² and Samphanthawong with 30182/km² are the most populous Amphoe (actually Khet, since these are in Bangkok).
