Source identity and administrative path
The source row behind Nanchang is GeoNames ID 1800163. Its recorded administrative path is Nanchang Shi → Jiangxi → China, and GeoNames classifies the place as a first-order administrative seat. Nanchang 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 2026-04-13; 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, Nanchang ranks 164 by recorded population. Inside the 296 selected China entries it ranks 55; inside the 632 entries in its broad region it ranks 103. Its 2,357,839 population value is 2.02 times the 1,165,375 median for the country cohort and 2.34 times the 1,008,426 regional median. Nanchang falls between the leading tenth and quarter of this atlas's China population cohort. Nanchang's recorded value reaches at least twice the country-cohort median in this snapshot. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.
Nearest-reference pattern
Nanchang's three nearest other atlas coordinates are Fuzhou (Jiangxi) at 93.223 km with 1,089,888 recorded people; Jiujiang at 114.424 km with 1,164,268 recorded people; Xinyu at 132.98 km with 839,488 recorded people. The closest-to-farthest distance spread is 39.757 km. Compared with Fuzhou (Jiangxi), Nanchang's recorded population is 2.16 times as large. Against Nanchang, Fuzhou (Jiangxi) follows Fuzhou Shi → Jiangxi → 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 second-order administrative seat rather than first-order administrative seat. Its recorded population is below Nanchang's. Against Nanchang, Jiujiang follows Jiujiang Shi → Jiangxi → 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 second-order administrative seat rather than first-order administrative seat. Its recorded population is below Nanchang's. Against Nanchang, Xinyu follows Xinyu → Jiangxi → 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 first-order administrative seat. Its recorded population is below Nanchang's. Its nearest-neighbor distance ranks 666 of 1,206 from shortest to longest in the same snapshot. Nanchang'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 1800163, the coordinate pair 28.6840 / 115.8531, country rank 55 of 296, and neighbor GeoNames 1810820 at 93.223 km bind Nanchang 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
Nanchang's reference point is 28.6840° north and 115.8531° east. The IANA identifier Asia/Shanghai is shared by 291 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. Nanchang's row carries both second- and first-order administrative labels. Nanchang's point falls in the lower-latitude coordinate band used by this atlas's row checks. Nanchang's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Nanchang, 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.
