Thailand’s 2025 Census: What You Need to Know

[Georgealbert]

Thailand’s 2025 Population and Housing Census officially began on 1 April 2025, with all eligible residents required to take part. Conducted by the National Statistical Office (NSO), the census is a vital process that helps shape national policies on infrastructure, healthcare, education, and economic planning.

 

The census, usually conducted every ten years, was originally scheduled for 2020 but was postponed due to the COVID-19 pandemic. This year’s survey will take place in two phases, with data collection running until 19 June 2025.

 

Who Must Complete the Census?

 

The census includes:

 

• Thai citizens residing in Thailand on Census Day – All Thai nationals present in the country on 1 April 2025 must participate.

 

• Thai and non-Thai residents temporarily abroad – Those who usually live in Thailand but are overseas on Census Day will still be counted.

 

• Thai government personnel stationed abroad – This includes military personnel, civil servants, and diplomats, as well as their families.

 

• Foreign residents who have lived in Thailand for at least three months – Non-Thai nationals who have been in Thailand since 1 January 2025 or earlier are also required to participate.

 

Who is Exempt from the Census?

 

Certain groups are not required to take part in the census, including:

• Foreign diplomats, military personnel, and civil servants based in Thailand, along with their families.

 

• Short-term foreign residents and tourists who have been in Thailand for less than three months prior to 1 April 2025.

 

• Refugees and undocumented migrants living in refugee camps, who are not included in the census data collection.

 

How Will the Census Be Conducted?

 

The census will take place in two phases, offering both online and in-person data collection:

 

Phase 1: Online Data Collection (1–20 April 2025)

 

During this period, residents can submit their information online through:

 

• The NSO website (here)

 

• The ‘Tang Rat’ application (available on Google Play and the App Store, but in Thai language only)

 

The online survey will be available in seven languages:

 

• Thai, English, Vietnamese, Burmese (Myanmar), Laotian, Cambodian, and Chinese

 

Participants can switch languages by selecting the option in the top-right corner of the website.

 

A family representative can fill out the form for an entire household, meaning individual household members do not need to submit separate entries.

 

Importantly, no sensitive personal data will be collected. The survey will not ask for ID numbers (passport or Thai ID), bank details, or income information. Instead, it will focus on:

 

• Household location

• Type of household and residence

• Number of people in the household

 

Phase 2: In-Person Data Collection (21 April – 19 June 2025)

 

For those who do not complete the survey online, census officials and volunteers will visit households in person.

 

The NSO has confirmed that census teams may include English-speaking volunteers, particularly in areas with large foreign communities, such as Pattaya, Bangkok, Phuket, and Chiang Mai.

 

Why Is the Census Important?

 

The census provides crucial data to support national development. Information collected will be categorised into:

 

• Population count

• Household numbers

• Types of buildings (including houses, shophouses, condominiums, and vacant rental properties)

 

Accurate census data allows the government to plan better public services, ensuring appropriate resources are allocated to education, healthcare, transport, and housing.

 

What Happens Next?

 

Once the census is completed, the NSO will analyse the data and publish its findings, which will guide long-term policy decisions.

For clarity this is the online census form, it expects one form per address, I don't know how it works for condo dwellers, perhaps a member could enlighten us.

It does appear to be a legal obligation under the Statistics Act, B.E. 2550 (2007) , although I don't see any specific penalties for non-compliance.

 

EDIT The act is here for those really, really interested https://thailawforum.com/database1/the-statistics-act.html

Since a few days I got two SMS from "MadeeNSO".

If only one form per household is required I won't care.

can we have the other thread about this restored or merged into this one ....I was writing a long reply  but when hit submit reply  the thread had been unceremoniously removed.

Since only addresses an not personal data are collected how do they know which occupants of any bulding, of any size have complied? 

I have just had a look at the form and it states;

"Please enter the information of all individuals who actually reside in the household".

I take that to mean that unless you live on your own that only one person per houshold fills in the form.

I shall leave this task to the wife.

Well if volunteers visited my apartment building I'm sure they could get all the info from the office manager.

What is wrong with so many Expats - why are they so negative?  Why not just complete the census online - easy peasy.  Something to hide??  Technically it is a requirement - but that is not why to do it. 

 

When there is a media statement in a 2-3 years saying the Thai Govt does not believe that there are many Expats living in Thailand, the lack of information provided in the Census of 2025 will be basis upon which they do it.  Immigration does not share the detailed numbers of Expats from those doing 90 days and extensions - unless asked for by PM or a Court - and even then it is their 'best guess'. They dont even share their data between the Provinces - there is SFA totalling going on - that would be work and they (Thai Govt workers) just dont care.  They dont know the death toll in that building collapse because they dont have the records of the Expat workers - let alone the illegals (and in this case mostly Myanmar people I would say). 

 

But as the bar girl said to the Priest - complete it or not - it is up to you.

But it does ask for DOB.

You can skip that but you have to enter your age.

 

Thailand is moving towards woke.

It asks for your sex and then the last question is asking for the sex that you prefer to be recognised as.

For ladyboys perhaps?

Wife has a couple of family members who work in the public service in Bangkok - they dont have a clue how many Expats (like us) are living in Thailand. They estimate about 2-3 Million Foreigners - but that includes all  workers (both seniors like Toyota, and building site workers, and those working for a living, and those retired or married - all foreigners). 

 

They literally have no idea how many Expats (Western and Japanese and Korean, etc etc) live in Thailand long term as either retired or married persons.  To find that out would mean adding up the number registered in each Province in one year and then categorising them all into various groups, and the adding that up across every Province in the whole country - that has never happened and probably never will.  And that only gives totals for that one year - they have no idea how many have lived here 1, 2 or 5 or 10+ years. 

 

The best chance for a true picture of Expats living in Thailand is if this Census reports that there are lots of Expats living in Thailand full time and who have been living here for many year - is if Expats do the Census. One question is how long have you lived there - and like I said the Census does not ask for ID or for proof or for any personal info other than name, address (it accepts minimal address details) and the month of birth (for age). 

 

It is a Census and the information is not specific to individuals - it is for obtaining totals of people living in all the locations across the country (you know - for future hospitals, roads, etc etc).  Over time it gives demographical information, and shows the changes from Census to Census - eg. last time 200K lived in XYX province, and now 350K live there.   Thais should do it too - but the majority dont and as always there is no enforcement - so they use averages.  The more Expats that complete it the better - that is all am I saying.

I managed to skip the complete DOB but had to enter my age.
