Source identity and administrative path
The source row behind Tangshan is GeoNames ID 1793346. Its recorded administrative path is Tangshan Shi → Hebei → China, and GeoNames classifies the place as a second-order administrative seat. Tangshan 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 2025-05-23; 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, Tangshan ranks 101 by recorded population. Inside the 296 selected China entries it ranks 38; inside the 632 entries in its broad region it ranks 65. Its 3,372,102 population value is 2.89 times the 1,165,375 median for the country cohort and 3.34 times the 1,008,426 regional median. Tangshan falls between the leading tenth and quarter of this atlas's China population cohort. Tangshan'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
Tangshan's three nearest other atlas coordinates are Tanggu at 83.195 km with 535,298 recorded people; Sanhe at 102.276 km with 965,075 recorded people; Tianjin at 102.915 km with 11,090,314 recorded people. The closest-to-farthest distance spread is 19.72 km. Compared with Tanggu, Tangshan's recorded population is 6.30 times as large. Against Tangshan, Tanggu follows Tianjin Municipality → Tianjin → 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 second-order administrative seat. Its recorded population is below Tangshan's. Against Tangshan, Sanhe 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 third-order administrative seat rather than second-order administrative seat. Its recorded population is below Tangshan's. Against Tangshan, Tianjin follows Tianjin Municipality → Tianjin → 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 first-order administrative seat rather than second-order administrative seat. Its recorded population is above Tangshan's. Its nearest-neighbor distance ranks 631 of 1,206 from shortest to longest in the same snapshot. Tangshan's nearest-coordinate gap belongs to the wider half 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 1793346, the coordinate pair 39.6438 / 118.1832, country rank 38 of 296, and neighbor GeoNames 1793424 at 83.195 km bind Tangshan 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
Tangshan's reference point is 39.6438° north and 118.1832° east. The IANA identifier Asia/Shanghai is shared by 291 city rows in this catalog, while the GeoNames class PPLA2 is shared by 341 rows. Tangshan's row carries both second- and first-order administrative labels. Tangshan's point falls in the middle-latitude coordinate band used by this atlas's row checks. Tangshan's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Tangshan, 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.
