Nakhon Pathom vs Ratchaburi: Business Base Compared (2026)
In short
Nakhon Pathom has the bigger business base, with 27,359 companies against Ratchaburi's 11,932 as of 17 July 2026. That is 2.29 times the company count. Revenue is only 1.97 times higher, at 736 billion baht against 374 billion. The gap shrinks because the average Ratchaburi company books 31.3 million baht, while the average Nakhon Pathom company books 26.9 million.
Which province has the bigger business base?
Nakhon Pathom, on both counts. It holds 27,359 registered companies (DBD, 2026), which ranks 13th among Thai provinces. Ratchaburi holds 11,932 and ranks 23rd. Put the two side by side and Nakhon Pathom has 15,427 more companies, or 2.29 times as many. On revenue it leads too, with 735.9 billion baht against 373.5 billion. That is a lead of 1.97 times, a little under the company ratio. The shortfall points to something more interesting than size. Ratchaburi companies are, on average, bigger earners.

Why the revenue story flips
Count companies and Nakhon Pathom looks more than twice the size. Count baht and the lead narrows. Ratchaburi's average company books 31.3 million baht, which is 16 percent more than the 26.9 million at Nakhon Pathom. The registry does not say why. A plausible reading is that Nakhon Pathom carries a longer tail of small registrations, while Ratchaburi's revenue rests on a thinner base of larger firms. Either way, neither province is a giant. Nakhon Pathom holds 0.92 percent of national reported revenue. Ratchaburi holds 0.47 percent. Both sit far below the national average of 40.3 million baht per company.
Why this matters
Anyone sizing a western Thai market should not stop at the headcount. A sales team that targets by company count will aim at Nakhon Pathom and find a crowded field of smaller accounts. A team that targets by revenue per company will find Ratchaburi's pool smaller but richer per name. The two provinces are neighbours on the same corridor, yet they reward different strategies. Count tells you how many doors there are. Revenue per company tells you what is behind them.
Definitions
- Registered company
- A juristic person recorded in the DBD registry under a province, whether or not it has filed financial statements.
- Revenue per company
- Province total reported revenue divided by all registered companies in that province, expressed in million baht.
- Aggregate
- A total or ratio computed across a whole group of companies rather than an average of individual company figures.
Assumptions
- Revenue comes only from companies that filed a financial statement, so provinces with a lower filing rate look smaller than they are.
- Companies are assigned to the province of their registered address, which may differ from where they operate.
- A head office registered in one province can book revenue earned elsewhere.
- Revenue per company mixes active and dormant registrations.
Methodology
Company counts and total reported revenue by province come from the Department of Business Development registry aggregates, computed on 17 July 2026 and described here as of 17 July 2026. Counts cover all registered juristic persons assigned to the province. Revenue sums filed financial statements only, so unfiled companies add to the count but not to revenue. Revenue per company divides province revenue by all registered companies, a deliberate simple measure that is lower than the average among filers. Comparison provinces in the chart use the same method. The national average uses 1,989,709 companies and about 80.15 trillion baht.
