Source identity and administrative path
The source row behind Chengdu is GeoNames ID 1815286. Its recorded administrative path is Chengdu Shi → Sichuan → China, and GeoNames classifies the place as a first-order administrative seat. Chengdu 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, Chengdu ranks 9 by recorded population. Inside the 296 selected China entries it ranks 5; inside the 632 entries in its broad region it ranks 6. Its 13,568,357 population value is 11.64 times the 1,165,375 median for the country cohort and 13.45 times the 1,008,426 regional median. Chengdu falls inside the leading tenth of this atlas's China population cohort. Chengdu'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
Chengdu's three nearest other atlas coordinates are Deyang at 59.679 km with 735,070 recorded people; Meishan at 72.67 km with 1,107,742 recorded people; Ziyang at 82.404 km with 905,729 recorded people. The closest-to-farthest distance spread is 22.725 km. Compared with Deyang, Chengdu's recorded population is 18.46 times as large. Against Chengdu, Deyang follows Deyang Shi → Sichuan → 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 Chengdu's. Against Chengdu, Meishan follows Meishan Shi → Sichuan → 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 Chengdu's. Against Chengdu, Ziyang follows Ziyang Shi → Sichuan → 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 second-order administrative seat rather than first-order administrative seat. Its recorded population is below Chengdu's. Its nearest-neighbor distance ranks 501 of 1,206 from shortest to longest in the same snapshot. Chengdu'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 1815286, the coordinate pair 30.6667 / 104.0667, country rank 5 of 296, and neighbor GeoNames 1812961 at 59.679 km bind Chengdu 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
Chengdu's reference point is 30.6667° north and 104.0667° 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. Chengdu's row carries both second- and first-order administrative labels. Chengdu's point falls in the middle-latitude coordinate band used by this atlas's row checks. Chengdu's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Chengdu, 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.
