Zhangjiagang

Source identity and administrative path

The source row behind Zhangjiagang is GeoNames ID 1787331. Its recorded administrative path is Suzhou Shi → Jiangsu → China, and GeoNames classifies the place as a third-order administrative seat.

Zhangjiagang 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 2026-01-16; 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, Zhangjiagang ranks 346 by recorded population. Inside the 296 selected China entries it ranks 113; inside the 632 entries in its broad region it ranks 202.

Its 1,432,044 population value is 1.23 times the 1,165,375 median for the country cohort and 1.42 times the 1,008,426 regional median. Zhangjiagang sits in the second quarter of this atlas's China population cohort.

Zhangjiagang'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

Zhangjiagang's three nearest other atlas coordinates are Jiangyin at 26.544 km with 1,779,515 recorded people; Changshu at 31.012 km with 1,677,050 recorded people; Nantong at 36.63 km with 2,273,326 recorded people. The closest-to-farthest distance spread is 10.086 km. Compared with Jiangyin, Zhangjiagang's recorded population is 0.80 times as large. Against Zhangjiagang, Jiangyin follows Wuxi Shi → Jiangsu → 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 the same third-order administrative seat class.

Its recorded population is above Zhangjiagang's. Against Zhangjiagang, Changshu follows Suzhou 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 third-order administrative seat class. Its recorded population is above Zhangjiagang's. Against Zhangjiagang, Nantong follows Nantong 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 second-order administrative seat rather than third-order administrative seat. Its recorded population is above Zhangjiagang's. Its nearest-neighbor distance ranks 301 of 1,206 from shortest to longest in the same snapshot. Zhangjiagang's nearest-coordinate gap falls between the tightest tenth and quarter of the atlas. 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 1787331, the coordinate pair 31.8650 / 120.5389, country rank 113 of 296, and neighbor GeoNames 1815251 at 26.544 km bind Zhangjiagang 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

Zhangjiagang's reference point is 31.8650° north and 120.5389° 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. Zhangjiagang's row carries both second- and first-order administrative labels.

Zhangjiagang's point falls in the middle-latitude coordinate band used by this atlas's row checks. Zhangjiagang's place-class field defines the narrower catalog cohort; its time zone is shared more broadly. GeoNames supplies no elevation for Zhangjiagang, 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.
