Source identity and administrative path
The source row behind Wenchang is GeoNames ID 1791544. Its recorded administrative path is Wenchang Shi → Hainan → China, and GeoNames classifies the place as a third-order administrative seat. Wenchang 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 2022-11-11; that date belongs to the source record, not to every transport or visitor detail in the real destination.
Population position inside fixed cohorts
Within the fixed 1,206-record atlas, Wenchang ranks 992 by recorded population. Inside the 296 selected China entries it ranks 263; inside the 632 entries in its broad region it ranks 529. Its 560,894 population value is 0.48 times the 1,165,375 median for the country cohort and 0.56 times the 1,008,426 regional median. Wenchang sits in the lower half of this atlas's selected China entries. Wenchang's recorded value is materially below the country-cohort median used here. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.
Nearest-reference pattern
Wenchang's three nearest other atlas coordinates are Qionghai at 49.422 km with 528,238 recorded people; Haikou at 71.826 km with 2,873,358 recorded people; Wanning at 94.502 km with 545,992 recorded people. The closest-to-farthest distance spread is 45.08 km. Compared with Qionghai, Wenchang's recorded population is 1.06 times as large. Against Wenchang, Qionghai follows Qionghai County → Hainan → China in the source. Its point has lower latitude and lower longitude; it belongs to the same selected China cohort, uses the shared Asia/Shanghai identifier, and carries second-order administrative seat rather than third-order administrative seat. Its recorded population is below Wenchang's. Against Wenchang, Haikou follows Haikou Shi → Hainan → China in the source. Its point has higher latitude and lower longitude; it belongs to the same selected China cohort, uses the shared Asia/Shanghai identifier, and carries first-order administrative seat rather than third-order administrative seat. Its recorded population is above Wenchang's. Against Wenchang, Wanning follows Wanning Shi → Hainan → China in the source. Its point has lower latitude and lower longitude; it belongs to the same selected China cohort, uses the shared Asia/Shanghai identifier, and carries second-order administrative seat rather than third-order administrative seat. Its recorded population is below Wenchang's. Its nearest-neighbor distance ranks 431 of 1,206 from shortest to longest in the same snapshot. Wenchang's nearest-coordinate gap sits in the second quarter 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 1791544, the coordinate pair 19.5516 / 110.8028, country rank 263 of 296, and neighbor GeoNames 1806488 at 49.422 km bind Wenchang to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Coordinate, time-zone and class cohorts
Wenchang's reference point is 19.5516° north and 110.8028° east. The IANA identifier Asia/Shanghai is shared by 291 city rows in this catalog, while the GeoNames class PPLA3 is shared by 60 rows. Wenchang's row carries both second- and first-order administrative labels. Wenchang's point falls in the lower-latitude coordinate band used by this atlas's row checks. Wenchang's place-class field defines the narrower catalog cohort; its time zone is shared more broadly. GeoNames supplies no elevation for Wenchang, 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.
