Source identity and administrative path
The source row behind Hefei is GeoNames ID 1808722. Its recorded administrative path is Hefei Shi → Anhui → China, and GeoNames classifies the place as a first-order administrative seat. Hefei 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 2026-04-13; 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, Hefei ranks 58 by recorded population. Inside the 296 selected China entries it ranks 20; inside the 632 entries in its broad region it ranks 37. Its 5,050,000 population value is 4.33 times the 1,165,375 median for the country cohort and 5.01 times the 1,008,426 regional median. Hefei falls inside the leading tenth of this atlas's China population cohort. Hefei'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
Hefei's three nearest other atlas coordinates are Lu'an at 73.592 km with 1,644,344 recorded people; Huainan at 88.89 km with 1,666,826 recorded people; Chuzhou at 108.497 km with 782,671 recorded people. The closest-to-farthest distance spread is 34.905 km. Compared with Lu'an, Hefei's recorded population is 3.07 times as large. Against Hefei, Lu'an follows Lu'an Shi → Anhui → 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 first-order administrative seat. Its recorded population is below Hefei's. Against Hefei, Huainan follows Huainan Shi → Anhui → 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 populated place rather than first-order administrative seat. Its recorded population is below Hefei's. Against Hefei, Chuzhou follows Chuzhou Shi → Anhui → 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 first-order administrative seat. Its recorded population is below Hefei's. Its nearest-neighbor distance ranks 577 of 1,206 from shortest to longest in the same snapshot. Hefei'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 1808722, the coordinate pair 31.8639 / 117.2808, country rank 20 of 296, and neighbor GeoNames 1802206 at 73.592 km bind Hefei 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
Hefei's reference point is 31.8639° north and 117.2808° east. The IANA identifier Asia/Shanghai is shared by 291 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. Hefei's row carries both second- and first-order administrative labels. Hefei's point falls in the middle-latitude coordinate band used by this atlas's row checks. Hefei's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Hefei, 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.
