Source identity and administrative path
The source row behind Changzhou is GeoNames ID 1815456. Its recorded administrative path is Changzhou Shi → Jiangsu → China, and GeoNames classifies the place as a second-order administrative seat. Changzhou 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 2025-03-09; 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, Changzhou ranks 105 by recorded population. Inside the 296 selected China entries it ranks 40; inside the 632 entries in its broad region it ranks 68. Its 3,290,918 population value is 2.82 times the 1,165,375 median for the country cohort and 3.26 times the 1,008,426 regional median. Changzhou falls between the leading tenth and quarter of this atlas's China population cohort. Changzhou'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
Changzhou's three nearest other atlas coordinates are Jiangyin at 32.947 km with 1,779,515 recorded people; Wuxi at 38.995 km with 4,396,835 recorded people; Yixing at 47.642 km with 1,285,785 recorded people. The closest-to-farthest distance spread is 14.695 km. Compared with Jiangyin, Changzhou's recorded population is 1.85 times as large. Against Changzhou, Jiangyin follows Wuxi Shi → Jiangsu → 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 Changzhou's. Against Changzhou, Wuxi follows Wuxi Shi → Jiangsu → 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 Changzhou's. Against Changzhou, Yixing follows Wuxi Shi → Jiangsu → 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 Changzhou's. Its nearest-neighbor distance ranks 336 of 1,206 from shortest to longest in the same snapshot. Changzhou'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 1815456, the coordinate pair 31.7736 / 119.9540, country rank 40 of 296, and neighbor GeoNames 1815251 at 32.947 km bind Changzhou 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
Changzhou's reference point is 31.7736° north and 119.9540° 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. Changzhou's row carries both second- and first-order administrative labels. Changzhou's point falls in the middle-latitude coordinate band used by this atlas's row checks. Changzhou's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Changzhou, 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.
