Source identity and administrative path
The source row behind Ziyang is GeoNames ID 1783683. Its recorded administrative path is Ziyang Shi → Sichuan → China, and GeoNames classifies the place as a second-order administrative seat. Ziyang 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 2025-08-19; 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, Ziyang ranks 612 by recorded population. Inside the 296 selected China entries it ranks 192; inside the 632 entries in its broad region it ranks 355. Its 905,729 population value is 0.78 times the 1,165,375 median for the country cohort and 0.90 times the 1,008,426 regional median. Ziyang sits in the lower half of this atlas's selected China entries. Ziyang'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.
Nearest-reference pattern
Ziyang's three nearest other atlas coordinates are Neijiang at 71.883 km with 1,251,095 recorded people; Meishan at 78.517 km with 1,107,742 recorded people; Chengdu at 82.404 km with 13,568,357 recorded people. The closest-to-farthest distance spread is 10.521 km. Compared with Neijiang, Ziyang's recorded population is 0.72 times as large. Against Ziyang, Neijiang follows Neijiang 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 third-order administrative seat rather than second-order administrative seat. Its recorded population is above Ziyang's. Against Ziyang, 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 the same second-order administrative seat class. Its recorded population is above Ziyang's. Against Ziyang, Chengdu follows Chengdu Shi → Sichuan → 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 first-order administrative seat rather than second-order administrative seat. Its recorded population is above Ziyang's. Its nearest-neighbor distance ranks 565 of 1,206 from shortest to longest in the same snapshot. Ziyang'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 1783683, the coordinate pair 30.1211 / 104.6481, country rank 192 of 296, and neighbor GeoNames 1799491 at 71.883 km bind Ziyang 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
Ziyang's reference point is 30.1211° north and 104.6481° 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. Ziyang's row carries both second- and first-order administrative labels. Ziyang's point falls in the middle-latitude coordinate band used by this atlas's row checks. Ziyang's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Ziyang, 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.
