Thailand's Median Province by Revenue per Company 2026
In short
Ranong ranks 39th of Thailand's 77 provinces when every one is sorted by revenue per registered company, as of 17 July 2026. Its companies earn about 14.6 million baht in revenue per firm. Thirty eight provinces score higher and thirty eight score lower, an exact split with no tie at the middle. That figure is barely more than a third of the national average of 40.3 million baht per company. Rank the same 77 provinces by total revenue instead and the median becomes Surin. Rank them by company count and the median becomes Phetchaburi, tied exactly with Chaiyaphum.
Which province is exactly average by this measure
Rank all 77 Thai provincial jurisdictions by revenue per registered company and Ranong lands exactly in the middle, at position 39 of 77, as of 17 July 2026. Its companies report about 14.6 million baht in revenue apiece. That works out to 38.7 billion baht in total revenue, filed by 2,651 registered firms. Thirty eight provinces post a higher figure than Ranong, and thirty eight post a lower one, with no tie sitting at the midpoint. That number is barely more than a third of the national average of 40.3 million baht per company, a sign that a small group of industrial provinces pulls the average well above what a typical province actually earns per firm. Rank the same 77 provinces by total revenue instead and the median province changes to Surin. Rank them by how many companies each one holds and the median becomes Phetchaburi, tied exactly with Chaiyaphum. Three different rankings, three different provinces sitting in the middle.

Why the median matters more than the average
A national average revenue per company gets dragged upward by petrochemical and industrial estates in Rayong, Prachin Buri and Chachoengsao, plus the sheer weight of Bangkok's registry. Rayong tops the entire ranking at 96.7 million baht per company. That is more than six and a half times Ranong's figure. Bangkok, despite holding more registered companies than any other province, ranks only fourth on this measure, behind Rayong, Prachin Buri and Phra Nakhon Si Ayutthaya. Ranong, by contrast, has no giant refineries or auto plants pulling its number up, and its 2,651 companies span the ordinary mix of trade, fishing, tourism and small services that most Thai provinces run on. That makes it a plainer stand-in for what a company in an average Thai province actually earns, something a national mean cannot show. National accounts data confirms the same pattern from a different angle, with Rayong also leading the country in per capita gross regional product (NESDC, 2025). A median is also far more stable than an average when a handful of outliers, tiny equity holding companies or one giant refinery, can distort the top of a list.
Definitions
- Revenue per company
- Total reported revenue for all companies registered in a province, divided by the number of registered companies in that province. It is an aggregate ratio, not the average of individual company margins.
- Median province
- The province that sits exactly in the middle of a ranked list of all 77 provinces, with an equal number of provinces scoring higher and lower.
- Registered company
- A juristic entity recorded in the DBD company registry, whether or not it has filed a financial statement or is currently active.
- National average
- The sum of total revenue across every province divided by the sum of registered companies across every province, a single economy wide figure that can be skewed by a few large provinces.
Assumptions
- Revenue per company blends large active filers with dormant companies that report no revenue, so it understates what an actively trading firm earns.
- A company's province reflects its registered address on file with the DBD, not necessarily where its factories, farms or stores actually operate.
- The mix of industries differs sharply from province to province, and this ranking does not adjust for that mix.
- Records with no assigned province, under 1 percent of the national total, are excluded from the 77 province ranking.
Methodology
Revenue per company for each province is total reported revenue for companies registered in that province divided by the number of registered companies in that province, drawn from the DBD registry as of 17 July 2026. All 77 provincial jurisdictions, including Bangkok, are ranked in descending order of this ratio, and the median is the value at position 39 of 77, the point where exactly 38 provinces rank higher and 38 rank lower. The denominator is every registered company on file in that province, including dormant firms with no reported revenue, so the ratio understates what an actively trading company earns. A small number of records with no assigned province, covering under 1 percent of the national total, are excluded from the ranking.
How we verified this
- All 77 provinces were ranked in descending order by total_revenue divided by entity_count, confirming Ranong at position 39 with 38 provinces scoring higher and 38 scoring lower.
- Ranong's revenue per company was recomputed directly as 38,727,378,850.04 baht divided by 2,651 companies, equal to 14,608,592.55 baht, matching the reported 14.6 million baht.
- The national average was recomputed as the sum of all 77 provinces' total revenue, 80,057,095,437,018.39 baht, divided by the sum of their registered companies, 1,986,137, equal to 40,307,942.22 baht, and Ranong's figure was confirmed at 36.2 percent of that average.
- The same 77 provinces were independently ranked by total_revenue alone, confirming Surin at position 39, and by entity_count alone, confirming Phetchaburi and Chaiyaphum tied at position 39 to 40 with 6,728 companies each, both distinct from Ranong.
- Rayong was confirmed as the top ranked province at 96,740,533.40 baht per company, and Mae Hong Son as the lowest at 3,861,094.93 baht per company, with Ranong's figure equal to about 15.1 percent of Rayong's and about 3.78 times Mae Hong Son's.

Frequently asked questions
Which Thai province is the median by revenue per company?
Ranong, at rank 39 of 77 provinces, with about 14.6 million baht in revenue per registered company as of 17 July 2026.
Is the median province the same no matter how you rank it?
No. By total revenue the median is Surin, and by company count the median is Phetchaburi, tied exactly with Chaiyaphum. Each ranking method points to a different province.
Why is Ranong's figure so far below the national average?
The national average of 40.3 million baht per company is pulled upward by a handful of industrial provinces. Rayong leads that group at 96.7 million baht per company. Ranong has no comparable heavy industry, so its figure sits close to what a typical Thai province actually earns per company.
Does a higher revenue per company mean a province is more prosperous?
Not directly. The figure blends a small number of large filers with many dormant companies that report no revenue, and it reflects each company's registered address rather than where it actually operates.
