Source identity and administrative path
The source row behind Taichung is GeoNames ID 1668399. Its recorded administrative path is Taichung City → Taiwan, and GeoNames classifies the place as a second-order administrative seat. Taichung 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 2025-06-14; 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, Taichung ranks 126 by recorded population. Inside the 6 selected Taiwan entries it ranks 3; inside the 632 entries in its broad region it ranks 83. Its 2,850,285 population value is 1.02 times the 2,793,973 median for the country cohort and 2.83 times the 1,008,426 regional median. Taichung is rank 3 among the 6 selected Taiwan entries, so a percentage band would overstate this small cohort. Taichung'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
Taichung's three nearest other atlas coordinates are Banqiao District at 124.801 km with 551,221 recorded people; New Taipei City at 128.308 km with 4,004,367 recorded people; Taipei at 131.938 km with 7,871,900 recorded people. The closest-to-farthest distance spread is 7.137 km. Compared with Banqiao District, Taichung's recorded population is 5.17 times as large. Against Taichung, Banqiao District follows New Taipei City → Taipei → Taiwan in the source. Its point has higher latitude and higher longitude; it belongs to the same selected Taiwan cohort, uses the shared Asia/Taipei identifier, and carries the same second-order administrative seat class. Its recorded population is below Taichung's. Against Taichung, New Taipei City follows New Taipei City → Taipei → Taiwan in the source. Its point has higher latitude and higher longitude; it belongs to the same selected Taiwan cohort, uses the shared Asia/Taipei identifier, and carries populated place rather than second-order administrative seat. Its recorded population is above Taichung's. Against Taichung, Taipei follows Taipei City → Taiwan in the source. Its point has higher latitude and higher longitude; it belongs to the same selected Taiwan cohort, uses the shared Asia/Taipei identifier, and carries capital of a political entity rather than second-order administrative seat. Its recorded population is above Taichung's. Its nearest-neighbor distance ranks 795 of 1,206 from shortest to longest in the same snapshot. Taichung's nearest-coordinate gap belongs to the wider half 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 1668399, the coordinate pair 24.1469 / 120.6839, country rank 3 of 6, and neighbor GeoNames 1670029 at 124.801 km bind Taichung 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
Taichung's reference point is 24.1469° north and 120.6839° east. The IANA identifier Asia/Taipei is shared by 6 city rows in this catalog, while the GeoNames class PPLA2 is shared by 341 rows. Taichung's row carries both second- and first-order administrative labels. Taichung's point falls in the lower-latitude coordinate band used by this atlas's row checks. Taichung's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Taichung, 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.
