Source identity and administrative path
The source row behind Longyan is GeoNames ID 1802276. Its recorded administrative path is Longyan Shi → Fujian → China, and GeoNames classifies the place as a second-order administrative seat. Longyan 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 2021-10-08; 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, Longyan ranks 532 by recorded population. Inside the 296 selected China entries it ranks 168; inside the 632 entries in its broad region it ranks 311. Its 1,025,087 population value is 0.88 times the 1,165,375 median for the country cohort and 1.02 times the 1,008,426 regional median. Longyan sits in the lower half of this atlas's selected China entries. Longyan'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.
Nearest-reference pattern
Longyan's three nearest other atlas coordinates are Zhangzhou at 89.687 km with 589,831 recorded people; Meizhou at 126.149 km with 992,351 recorded people; Xiamen at 126.173 km with 4,617,251 recorded people. The closest-to-farthest distance spread is 36.486 km. Compared with Zhangzhou, Longyan's recorded population is 1.74 times as large. Against Longyan, Zhangzhou follows Zhangzhou Shi → Fujian → China in the source. Its point has lower 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 Longyan's. Against Longyan, Meizhou follows Meizhou Shi → Guangdong → 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 the same second-order administrative seat class. Its recorded population is below Longyan's. Against Longyan, Xiamen follows Fujian → China in the source. Its point has lower 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 above Longyan's. Its nearest-neighbor distance ranks 652 of 1,206 from shortest to longest in the same snapshot. Longyan'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 1802276, the coordinate pair 25.0749 / 117.0178, country rank 168 of 296, and neighbor GeoNames 1785018 at 89.687 km bind Longyan 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
Longyan's reference point is 25.0749° north and 117.0178° 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. Longyan's row carries both second- and first-order administrative labels. Longyan's point falls in the lower-latitude coordinate band used by this atlas's row checks. Longyan's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Longyan, 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.
