Source identity and administrative path
The source row behind Nanchong is GeoNames ID 1800146. Its recorded administrative path is Nanchong Shi → Sichuan → China, and GeoNames classifies the place as a second-order administrative seat. Nanchong 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 2021-10-19; 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, Nanchong ranks 226 by recorded population. Inside the 296 selected China entries it ranks 75; inside the 632 entries in its broad region it ranks 134. Its 1,858,875 population value is 1.60 times the 1,165,375 median for the country cohort and 1.84 times the 1,008,426 regional median. Nanchong sits in the second quarter of this atlas's China population cohort. Nanchong's recorded value is above the country-cohort median but remains below twice that benchmark. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.
Nearest-reference pattern
Nanchong's three nearest other atlas coordinates are Suining at 58.413 km with 656,760 recorded people; Guang'an at 63.759 km with 858,159 recorded people; Bazhong at 134.888 km with 2,712,894 recorded people. The closest-to-farthest distance spread is 76.475 km. Compared with Suining, Nanchong's recorded population is 2.83 times as large. Against Nanchong, Suining follows Suining Shi → Sichuan → 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 third-order administrative seat rather than second-order administrative seat. Its recorded population is below Nanchong's. Against Nanchong, Guang'an follows Guang'an Shi → Sichuan → 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 Nanchong's. Against Nanchong, Bazhong follows Bazhong Shi → Sichuan → 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 above Nanchong's. Its nearest-neighbor distance ranks 493 of 1,206 from shortest to longest in the same snapshot. Nanchong'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 1800146, the coordinate pair 30.7951 / 106.0847, country rank 75 of 296, and neighbor GeoNames 1793900 at 58.413 km bind Nanchong 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
Nanchong's reference point is 30.7951° north and 106.0847° 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. Nanchong's row carries both second- and first-order administrative labels. Nanchong's point falls in the middle-latitude coordinate band used by this atlas's row checks. Nanchong's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Nanchong, 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.
