Source identity and administrative path
The source row behind Zhangjiakou is GeoNames ID 2033196. Its recorded administrative path is Zhangjiakou Shi → Hebei → China, and GeoNames classifies the place as a second-order administrative seat. Zhangjiakou 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 2022-02-17; 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, Zhangjiakou ranks 795 by recorded population. Inside the 296 selected China entries it ranks 229; inside the 632 entries in its broad region it ranks 444. Its 692,602 population value is 0.59 times the 1,165,375 median for the country cohort and 0.69 times the 1,008,426 regional median. Zhangjiakou sits in the lower half of this atlas's selected China entries. Zhangjiakou'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
Zhangjiakou's three nearest other atlas coordinates are Ulanqab at 147.977 km with 550,231 recorded people; Datong at 154.15 km with 1,850,000 recorded people; Beijing at 161.883 km with 18,960,744 recorded people. The closest-to-farthest distance spread is 13.906 km. Compared with Ulanqab, Zhangjiakou's recorded population is 1.26 times as large. Against Zhangjiakou, Ulanqab follows Wulanchabu Shi → Inner Mongolia → 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 the same second-order administrative seat class. Its recorded population is below Zhangjiakou's. Against Zhangjiakou, Datong follows Datong Shi → Shanxi → 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 above Zhangjiakou's. Against Zhangjiakou, Beijing follows Beijing → 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 capital of a political entity rather than second-order administrative seat. Its recorded population is above Zhangjiakou's. Its nearest-neighbor distance ranks 871 of 1,206 from shortest to longest in the same snapshot. Zhangjiakou'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 2033196, the coordinate pair 40.7834 / 114.8714, country rank 229 of 296, and neighbor GeoNames 8335361 at 147.977 km bind Zhangjiakou 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
Zhangjiakou's reference point is 40.7834° north and 114.8714° 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. Zhangjiakou's row carries both second- and first-order administrative labels. Zhangjiakou's point falls in the middle-latitude coordinate band used by this atlas's row checks. Zhangjiakou's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Zhangjiakou, 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.
