01What the data says — and does not say
This page separates the checked GeoNames row for Sanhe—965,075, Asia/Shanghai, and source coordinates—from live travel claims. Those fields identify and compare the record; they do not prove current transport, accessibility, census totals, or a City Atlas Club visit.
02This city's dataset fingerprint
The source row behind Sanhe is GeoNames ID 1796823. Its recorded administrative path is Langfang Shi → Hebei → China, and GeoNames classifies the place as a third-order administrative seat. Sanhe 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 2025-11-26; that date belongs to the source record, not to every transport or visitor detail in the real destination.
Within the fixed 1,206-record atlas, Sanhe ranks 577 by recorded population. Inside the 296 selected China entries it ranks 183; inside the 632 entries in its broad region it ranks 334. Its 965,075 population value is 0.83 times the 1,165,375 median for the country cohort and 0.96 times the 1,008,426 regional median. Sanhe sits in the lower half of this atlas's selected China entries. Sanhe's recorded value stays within one quarter of the country-cohort median used here. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.
Sanhe's three nearest other atlas coordinates are Beijing at 57.83 km with 18,960,744 recorded people; Langfang at 59.41 km with 868,066 recorded people; Tianjin at 93.668 km with 11,090,314 recorded people. The closest-to-farthest distance spread is 35.838 km. Compared with Beijing, Sanhe's recorded population is 0.05 times as large. Against Sanhe, Beijing follows Beijing → 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 capital of a political entity rather than third-order administrative seat. Its recorded population is above Sanhe's. Against Sanhe, Langfang follows Langfang Shi → Hebei → 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 second-order administrative seat rather than third-order administrative seat. Its recorded population is below Sanhe's. Against Sanhe, Tianjin follows Tianjin Municipality → Tianjin → 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 first-order administrative seat rather than third-order administrative seat. Its recorded population is above Sanhe's. Its nearest-neighbor distance ranks 489 of 1,206 from shortest to longest in the same snapshot. Sanhe'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 1796823, the coordinate pair 39.9805 / 117.0689, country rank 183 of 296, and neighbor GeoNames 1816670 at 57.83 km bind Sanhe to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Sanhe's reference point is 39.9805° north and 117.0689° 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. Sanhe's row carries both second- and first-order administrative labels. Sanhe's point falls in the middle-latitude coordinate band used by this atlas's row checks. Sanhe's place-class field defines the narrower catalog cohort; its time zone is shared more broadly. GeoNames supplies no elevation for Sanhe, 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.
