DOPA Wchecklname — surname existence signal (th-corpus seed) on the left; every record we hold for Thailand on the right. A dashed line means the name is not in our top ranks for this country at all.

The register counts one population in one year — everyone it enumerates, once. Our corpus counts records: historical registers going back decades, the diaspora, business and place records, and several generations of births. A name that was common two generations ago outranks a name common today; a name whose spelling scatters across sources (diacritics dropped, transliterated differently) loses ground, because only its dominant spelling is ranked.

Characteristic of Thailand

Not the most common names — the most distinctive ones. A name appears here when Thailand holds a larger share of its bearers than the world does, weighted by how much of the country's whole name distribution it accounts for.

    What we know about this register

    Same BORA Wchecklname surname-registration eligibility API as th-bora-wchecklname, re-queried here with the th-corpus Thai-script surname list (9,836 names) as seed. Endpoint (GET): https://stat.bora.dopa.go.th/Wchecklname/connectAPI/api_forward.php?API=/api/gen/namereg/v1/ch2/?lnameWrite=<surname>&lnameRead=<reading>&action=1 The SPA (Vue, single /CheckLname route) builds this from the JS chunk; lnameRead (phonetic reading) does NOT affect the duplicate lookup so the surname is passed as its own reading. IMPORTANT: this is a BINARY existence check, NOT a frequency counter — no count is ever returned. HTTP 400 {"info":"ซ้ำกับชื่อสกุลในฐานข้อมูลการทะเบียนราษฎร"} (duplicate in civil registry) = attested surname (POSITIVE, evidence=binary); HTTP 200 returnStatus=1 / empty record = registrable, not in registry (NEGATIVE, evidence=binary_absent, count=0). No CheckFname/given-name endpoint exists — surnames only. No per-IP rate limit observed (15 rapid requests OK; direct .go.th access, no proxy needed; sustained ~1 req/s single-threaded). Negatives are recorded. First pass (time-boxed ~25 min, resumable): 1,521 attested + 4 absent of 9,836 seed surnames. Raw cache: raw/TH/dopa_namecount_cache.jsonl (one JSON per name: name/exists/http_status/info/ts). Re-runnable: scripts/fetch_th_dopa.py (skips cached names) + scripts/build_th_dopa_parquet.py. Output: normalized/TH/th-dopa-namecount.parquet. CORRECTED 2026-07-25: the "first pass (time-boxed ~25 min)" figure of 1,521 attested surnames in this note is stale — the parquet now holds 1,922,591 rows, i.e. this id carries the full BORA Wchecklname sweep (see th-bora-wchecklname, which is a duplicate id for the same extraction).

About this data

Official figures are reproduced from the register named beside them, at the year named beside them, and are never combined across registers. The "across all records" ranking counts records in our own corpus — historical registers, the diaspora, business and place records — and is not a population count. Bearer estimates are omitted where a name accounts for more than a quarter of a country's records, because the estimate is not defensible there. Names listed by reference works and licensed name dictionaries are cited as attesting a name; their figures are not published.
