01What the data says — and does not say
This page separates the checked GeoNames row for Sanya—1,031,396, Asia/Shanghai, and source coordinates—from live travel claims. Those fields identify and compare the record; they do not prove current transport, accessibility, census totals, or a City Atlas Club visit.
Wikidata's localized description: prefecture-level city in Hainan, China.
02This city's dataset fingerprint
The source row behind Sanya is GeoNames ID 1796556. Its recorded administrative path is Sanya Shi → Hainan → China, and GeoNames classifies the place as a second-order administrative seat. Sanya occurs once as a primary city label in this atlas sample; the numeric ID remains the durable source key if names change. The city row itself was updated 2024-02-08; that date belongs to the source record, not to every transport or visitor detail in the real destination.
Within the fixed 1,206-record atlas, Sanya ranks 524 by recorded population. Inside the 296 selected China entries it ranks 166; inside the 632 entries in its broad region it ranks 304. Its 1,031,396 population value is 0.89 times the 1,165,375 median for the country cohort and 1.02 times the 1,008,426 regional median. Sanya sits in the lower half of this atlas's selected China entries. Sanya's recorded value stays within one quarter of the country-cohort median used here. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.
Sanya's three nearest other atlas coordinates are Wanning at 110.342 km with 545,992 recorded people; Qionghai at 148.923 km with 528,238 recorded people; Wenchang at 198.284 km with 560,894 recorded people. The closest-to-farthest distance spread is 87.942 km. Compared with Wanning, Sanya's recorded population is 1.89 times as large. Against Sanya, Wanning follows Wanning Shi → Hainan → China in the source. Its point has higher latitude and higher longitude; it belongs to the same selected China cohort, uses the shared Asia/Shanghai identifier, and carries the same second-order administrative seat class. Its recorded population is below Sanya's. Against Sanya, Qionghai follows Qionghai County → Hainan → China in the source. Its point has higher latitude and higher longitude; it belongs to the same selected China cohort, uses the shared Asia/Shanghai identifier, and carries the same second-order administrative seat class. Its recorded population is below Sanya's. Against Sanya, Wenchang follows Wenchang Shi → Hainan → China in the source. Its point has higher latitude and higher longitude; it belongs to the same selected China cohort, uses the shared Asia/Shanghai identifier, and carries third-order administrative seat rather than second-order administrative seat. Its recorded population is below Sanya's. Its nearest-neighbor distance ranks 735 of 1,206 from shortest to longest in the same snapshot. Sanya's nearest-coordinate gap belongs to the wider half of atlas distances. This pattern can reveal whether other catalog references are geographically close, but it cannot establish whether a border crossing is possible or practical, or whether rail, road, fare, or journey-time connections exist. Read as one record signature, GeoNames 1796556, the coordinate pair 18.2544 / 109.5095, country rank 166 of 296, and neighbor GeoNames 1791779 at 110.342 km bind Sanya to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Sanya's reference point is 18.2544° north and 109.5095° east. The IANA identifier Asia/Shanghai is shared by 291 city rows in this catalog, while the GeoNames class PPLA2 is shared by 341 rows. Sanya's row carries both second- and first-order administrative labels. Sanya's point falls in the lower-latitude coordinate band used by this atlas's row checks. Sanya's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Sanya, so the profile preserves that missing value instead of guessing terrain. Together these fields form a reproducible identity check for this page, not a claim about walkability, climate or accessibility.
