Tanggu

Source identity and administrative path

The source row behind Tanggu is GeoNames ID 1793424. Its recorded administrative path is Tianjin Municipality → Tianjin → China, and GeoNames classifies the place as a populated place.

Tanggu 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 2021-09-20; 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, Tanggu ranks 1,055 by recorded population. Inside the 296 selected China entries it ranks 276; inside the 632 entries in its broad region it ranks 558.

Its 535,298 population value is 0.46 times the 1,165,375 median for the country cohort and 0.53 times the 1,008,426 regional median. Tanggu sits in the lower half of this atlas's selected China entries.

Tanggu'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

Tanggu's three nearest other atlas coordinates are Tianjin at 42.767 km with 11,090,314 recorded people; Tangshan at 83.195 km with 3,372,102 recorded people; Langfang at 97.606 km with 868,066 recorded people. The closest-to-farthest distance spread is 54.839 km. Compared with Tianjin, Tanggu's recorded population is 0.05 times as large. Against Tanggu, Tianjin follows Tianjin Municipality → Tianjin → 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 first-order administrative seat rather than populated place.

Its recorded population is above Tanggu's. Against Tanggu, Tangshan follows Tangshan Shi → Hebei → 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 populated place. Its recorded population is above Tanggu's. Against Tanggu, Langfang follows Langfang Shi → Hebei → 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 second-order administrative seat rather than populated place. Its recorded population is above Tanggu's. Its nearest-neighbor distance ranks 377 of 1,206 from shortest to longest in the same snapshot. Tanggu's nearest-coordinate gap sits in the second quarter of atlas distances. 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 1793424, the coordinate pair 39.0211 / 117.6469, country rank 276 of 296, and neighbor GeoNames 1792947 at 42.767 km bind Tanggu 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

Tanggu's reference point is 39.0211° north and 117.6469° east. The IANA identifier Asia/Shanghai is shared by 291 city rows in this catalog, while the GeoNames class PPL is shared by 243 rows. Tanggu's row carries both second- and first-order administrative labels.

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