Source identity and administrative path
The source row behind Lu'an is GeoNames ID 1802206. Its recorded administrative path is Lu'an Shi → Anhui → China, and GeoNames classifies the place as a second-order administrative seat. Lu’an 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 2021-10-18; 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, Lu'an ranks 276 by recorded population. Inside the 296 selected China entries it ranks 89; inside the 632 entries in its broad region it ranks 160. Its 1,644,344 population value is 1.41 times the 1,165,375 median for the country cohort and 1.63 times the 1,008,426 regional median. Lu'an sits in the second quarter of this atlas's China population cohort. Lu'an's recorded value is above the country-cohort median but remains below twice that benchmark. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.
Nearest-reference pattern
Lu'an's three nearest other atlas coordinates are Hefei at 73.592 km with 5,050,000 recorded people; Huainan at 108.867 km with 1,666,826 recorded people; Anqing at 144.95 km with 804,493 recorded people. The closest-to-farthest distance spread is 71.358 km. Compared with Hefei, Lu'an's recorded population is 0.33 times as large. Against Lu'an, Hefei follows Hefei 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 first-order administrative seat rather than second-order administrative seat. Its recorded population is above Lu'an's. Against Lu'an, Huainan follows Huainan 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 populated place rather than second-order administrative seat. Its recorded population is above Lu'an's. Against Lu'an, Anqing follows Anqing Shi → Anhui → 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 the same second-order administrative seat class. Its recorded population is below Lu'an's. Its nearest-neighbor distance ranks 577 of 1,206 from shortest to longest in the same snapshot. Lu'an'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 1802206, the coordinate pair 31.7356 / 116.5169, country rank 89 of 296, and neighbor GeoNames 1808722 at 73.592 km bind Lu'an 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
Lu'an's reference point is 31.7356° north and 116.5169° 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. Lu'an's row carries both second- and first-order administrative labels. Lu'an's point falls in the middle-latitude coordinate band used by this atlas's row checks. Lu'an's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Lu'an, 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.
