Census 1937 district data

The 1937 census reports include the male and female population numbers for each district (Amphoe), a table covering 30 pages in the publication. I have now completed to convert these numbers into a spreadsheet, as well as my XML format, of all the 408 districts covered by the report. While I have no idea how much these numbers differed from the real numbers back then due to shortcomings in the way the census was conducted, but the numbers in the report all sum up perfectly except two or three obvious number errors - e.g. for Lang Suan the female population was given as 21893 instead of 12893.

As this table includes a column with the ratio between male and female population, there are some interesting strange cases. While for most district the ratio is between 87% and  130%, there are a few district where the male population is very dominant. Bannang Sata in Yala has more than the double number of men than women (4994 vs. 2427), also Samphanthawong in Bangkok (then Phra Nakhon province) has 42200 men compared to 27760 women. The later case is easy to explain - this district covers Chinatown, which at that time had many unmarried male Chinese workers. This can also be seen in the percentage of Thai vs. non-Thai citizen - Phra Nakhon had 29.7% of non-Thai citizen, Yala 13.4%, also Phuket and Ranong had more than 10%. These two provinces also had quite some Chinese workers, at that time the tin mining was still a big part of the local economy.

Though this table only included the full district and counted the minor districts (King Amphoe) together with the district which supervised it, it also made a good cross-check of whether my district data is complete. From all the districts which exist today, and where I had the dates of when they became full districts, only the district Thung Yai in Nakhon Si Thammarat - then named Tha Yang (กิ่งอำเภอท่ายาง) - was missing, because its upgrade to a full district sometime between 1941 and 1948 apparently wasn't published in the Royal Gazette. The only other special cases are three districts in Bangkok which were abolished later - Bang Sue, Bang Phlat, Bukkhalo and Nang Loeng were abolished in 1938, the first two were created again in 1989. While these districts are included in the data, interestingly the districts already uses the names changed in 1938, which among other changes gave the capital districts the Amphoe Mueang names.
