Source identity and administrative path
The source row behind Tuen Mun is GeoNames ID 1818446. Its recorded administrative path is Tuen Mun → Hong Kong, and GeoNames classifies the place as a first-order administrative seat. Tuen Mun 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 2025-08-25; 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, Tuen Mun ranks 1,127 by recorded population. Inside the 4 selected Hong Kong entries it ranks 3; inside the 632 entries in its broad region it ranks 592. Its 507,900 population value is 0.69 times the 732,350 median for the country cohort and 0.50 times the 1,008,426 regional median. Tuen Mun is rank 3 among the 4 selected Hong Kong entries, so a percentage band would overstate this small cohort. Tuen Mun's recorded value is materially below 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

The closest-to-farthest distance spread is 1.422 km. Compared with Shenzhen, Tuen Mun's recorded population is 0.03 times as large. Against Tuen Mun, Shenzhen follows Shenzhen → Guangdong → China in the source. Its point has higher latitude and higher longitude; it belongs to the selected China cohort rather than Hong Kong, uses Asia/Shanghai instead of Asia/Hong_Kong, and carries second-order administrative seat rather than first-order administrative seat. Its recorded population is above Tuen Mun's. Against Tuen Mun, Bao'an follows Guangdong → China in the source. Its point has higher latitude and lower longitude; it belongs to the selected China cohort rather than Hong Kong, uses Asia/Shanghai instead of Asia/Hong_Kong, and carries third-order administrative seat rather than first-order administrative seat. Its recorded population is above Tuen Mun's. Against Tuen Mun, Victoria follows Central and Western → Hong Kong in the source. Its point has lower latitude and higher longitude; it belongs to the same selected Hong Kong cohort, uses the shared Asia/Hong_Kong identifier, and carries populated place rather than first-order administrative seat. Its recorded population is above Tuen Mun's. Its nearest-neighbor distance ranks 259 of 1,206 from shortest to longest in the same snapshot. Tuen Mun's nearest-coordinate gap falls between the tightest tenth and quarter of the atlas. 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 1818446, the coordinate pair 22.3918 / 113.9716, country rank 3 of 4, and neighbor GeoNames 1795565 at 19.779 km bind Tuen Mun 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
Tuen Mun's reference point is 22.3918° north and 113.9716° east. The IANA identifier Asia/Hong_Kong is shared by 4 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. Tuen Mun's row carries a first-order administrative label but no second-order label. Tuen Mun's point falls in the lower-latitude coordinate band used by this atlas's row checks. Tuen Mun's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Tuen Mun, 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.
