Source identity and administrative path
The source row behind Jiading is GeoNames ID 1806508. Its recorded administrative path is Shanghai Municipality → Shanghai → China, and GeoNames classifies the place as a fourth-order administrative seat. Jiading 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, Jiading ranks 221 by recorded population. Inside the 296 selected China entries it ranks 73; inside the 632 entries in its broad region it ranks 132. Its 1,886,100 population value is 1.62 times the 1,165,375 median for the country cohort and 1.87 times the 1,008,426 regional median. Jiading falls between the leading tenth and quarter of this atlas's China population cohort. Jiading'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
Jiading's three nearest other atlas coordinates are Taicang at 15.882 km with 831,113 recorded people; Putuo at 20.356 km with 1,239,100 recorded people; Baoshan (Shanghai) at 23.382 km with 2,265,900 recorded people. The closest-to-farthest distance spread is 7.5 km. Compared with Taicang, Jiading's recorded population is 2.27 times as large. Against Jiading, Taicang follows Suzhou 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 third-order administrative seat rather than fourth-order administrative seat. Its recorded population is below Jiading's. Against Jiading, Putuo 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 populated place rather than fourth-order administrative seat. Its recorded population is below Jiading's. Against Jiading, Baoshan (Shanghai) follows 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 third-order administrative seat rather than fourth-order administrative seat. Its recorded population is above Jiading's. Its nearest-neighbor distance ranks 218 of 1,206 from shortest to longest in the same snapshot. Jiading'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 1806508, the coordinate pair 31.3858 / 121.2447, country rank 73 of 296, and neighbor GeoNames 1793703 at 15.882 km bind Jiading 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
Jiading's reference point is 31.3858° north and 121.2447° east. The IANA identifier Asia/Shanghai is shared by 291 city rows in this catalog, while the GeoNames class PPLA4 is shared by 4 rows. Jiading's row carries both second- and first-order administrative labels. Jiading's point falls in the middle-latitude coordinate band used by this atlas's row checks. Jiading's place-class field defines the narrower catalog cohort; its time zone is shared more broadly. GeoNames supplies no elevation for Jiading, 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.
