Source identity and administrative path
The source row behind Changning is GeoNames ID 1815611. Its recorded administrative path is Shanghai Municipality → Shanghai → China, and GeoNames classifies the place as a third-order administrative seat. Changning 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 2026-03-31; 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, Changning ranks 791 by recorded population. Inside the 296 selected China entries it ranks 228; inside the 632 entries in its broad region it ranks 442. Its 694,900 population value is 0.60 times the 1,165,375 median for the country cohort and 0.69 times the 1,008,426 regional median. Changning sits in the lower half of this atlas's selected China entries. Changning's recorded value is materially below 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
Changning's three nearest other atlas coordinates are Xuhui at 3.438 km with 1,109,800 recorded people; Shanghai at 3.56 km with 24,874,500 recorded people; Putuo at 4.78 km with 1,239,100 recorded people. The closest-to-farthest distance spread is 1.342 km. Compared with Xuhui, Changning's recorded population is 0.63 times as large. Against Changning, Xuhui follows Shanghai Municipality → Shanghai → 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 Changning's. Against Changning, Shanghai follows Shanghai Municipality → Shanghai → 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 first-order administrative seat rather than third-order administrative seat. Its recorded population is above Changning's. Against Changning, Putuo follows Shanghai Municipality → Shanghai → 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 populated place rather than third-order administrative seat. Its recorded population is above Changning's. Its nearest-neighbor distance ranks 27 of 1,206 from shortest to longest in the same snapshot. Changning's nearest-coordinate gap belongs to the tightest tenth 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 1815611, the coordinate pair 31.2174 / 121.4211, country rank 228 of 296, and neighbor GeoNames 1787957 at 3.438 km bind Changning 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
Changning's reference point is 31.2174° north and 121.4211° 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. Changning's row carries both second- and first-order administrative labels. Changning's point falls in the middle-latitude coordinate band used by this atlas's row checks. Changning's place-class field defines the narrower catalog cohort; its time zone is shared more broadly. GeoNames supplies no elevation for Changning, 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.
