Hongkou

Source identity and administrative path

The source row behind Hongkou is GeoNames ID 1808090. Its recorded administrative path is Shanghai Municipality → Shanghai → China, and GeoNames classifies the place as a third-order administrative seat.

Hongkou 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, Hongkou ranks 805 by recorded population. Inside the 296 selected China entries it ranks 234; inside the 632 entries in its broad region it ranks 450.

Its 687,500 population value is 0.59 times the 1,165,375 median for the country cohort and 0.68 times the 1,008,426 regional median. Hongkou sits in the lower half of this atlas's selected China entries.

Hongkou'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

Hongkou's three nearest other atlas coordinates are Pudong at 1.581 km with 5,681,512 recorded people; Huangpu at 1.717 km with 504,700 recorded people; Yangpu at 3.134 km with 1,210,800 recorded people. The closest-to-farthest distance spread is 1.553 km. Compared with Pudong, Hongkou's recorded population is 0.12 times as large. Against Hongkou, Pudong 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 fourth-order administrative seat rather than third-order administrative seat.

Its recorded population is above Hongkou's. Against Hongkou, 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 third-order administrative seat. Its recorded population is below Hongkou's. Against Hongkou, 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 the same third-order administrative seat class. Its recorded population is above Hongkou's. Its nearest-neighbor distance ranks 11 of 1,206 from shortest to longest in the same snapshot. Hongkou'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 1808090, the coordinate pair 31.2500 / 121.4892, country rank 234 of 296, and neighbor GeoNames 1798524 at 1.581 km bind Hongkou 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

Hongkou's reference point is 31.2500° north and 121.4892° 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. Hongkou's row carries both second- and first-order administrative labels.

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