Source identity and administrative path
The source row behind Pudong is GeoNames ID 1798524. Its recorded administrative path is Shanghai Municipality → Shanghai → China, and GeoNames classifies the place as a fourth-order administrative seat. Pudong 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, Pudong ranks 49 by recorded population. Inside the 296 selected China entries it ranks 18; inside the 632 entries in its broad region it ranks 33. Its 5,681,512 population value is 4.88 times the 1,165,375 median for the country cohort and 5.63 times the 1,008,426 regional median. Pudong falls inside the leading tenth of this atlas's China population cohort. Pudong'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
Pudong's three nearest other atlas coordinates are Hongkou at 1.581 km with 687,500 recorded people; Huangpu at 2.185 km with 504,700 recorded people; Yangpu at 2.989 km with 1,210,800 recorded people. The closest-to-farthest distance spread is 1.408 km. Compared with Hongkou, Pudong's recorded population is 8.26 times as large. Against Pudong, Hongkou 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 third-order administrative seat rather than fourth-order administrative seat. Its recorded population is below Pudong's. Against Pudong, Huangpu follows Shanghai Municipality → Shanghai → 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 populated place rather than fourth-order administrative seat. Its recorded population is below Pudong's. Against Pudong, Yangpu 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 third-order administrative seat rather than fourth-order administrative seat. Its recorded population is below Pudong's. Its nearest-neighbor distance ranks 11 of 1,206 from shortest to longest in the same snapshot. Pudong'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 1798524, the coordinate pair 31.2400 / 121.5009, country rank 18 of 296, and neighbor GeoNames 1808090 at 1.581 km bind Pudong 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
Pudong's reference point is 31.2400° north and 121.5009° 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. Pudong's row carries both second- and first-order administrative labels. Pudong's point falls in the middle-latitude coordinate band used by this atlas's row checks. Pudong's place-class field defines the narrower catalog cohort; its time zone is shared more broadly. GeoNames supplies no elevation for Pudong, 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.
