01What the data says — and does not say
This page separates the checked GeoNames row for Perth—2,384,371, Australia/Perth, and source coordinates—from live travel claims. Those fields identify and compare the record; they do not prove current transport, accessibility, census totals, or a City Atlas Club visit.
Wikidata's localized description: capital city of Western Australia, Australia.
02This city's dataset fingerprint
The source row behind Perth is GeoNames ID 2063523. Its recorded administrative path is Perth → Western Australia → Australia, and GeoNames classifies the place as a first-order administrative seat. Perth 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 2026-06-24; that date belongs to the source record, not to every transport or visitor detail in the real destination.
Within the fixed 1,206-record atlas, Perth ranks 161 by recorded population. Inside the 7 selected Australia entries it ranks 4; inside the 8 entries in its broad region it ranks 4. Its 2,384,371 population value is 1.00 times the 2,384,371 median for the country cohort and 1.21 times the 1,965,786 regional median. Perth is rank 4 among the 7 selected Australia entries, so a percentage band would overstate this small cohort. Perth'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.
Perth's three nearest other atlas coordinates are Adelaide at 2,130.795 km with 1,469,163 recorded people; Denpasar at 2,591.946 km with 670,210 recorded people; Malang at 2,686.492 km with 889,359 recorded people. The closest-to-farthest distance spread is 555.697 km. Compared with Adelaide, Perth's recorded population is 1.62 times as large. Against Perth, Adelaide follows Adelaide → South Australia → Australia in the source. Its point has lower latitude and higher longitude; it belongs to the same selected Australia cohort, uses Australia/Adelaide instead of Australia/Perth, and carries the same first-order administrative seat class. Its recorded population is below Perth's. Against Perth, Denpasar follows Kota Denpasar → Bali → Indonesia in the source. Its point has higher latitude and lower longitude; it belongs to the selected Indonesia cohort rather than Australia, uses Asia/Makassar instead of Australia/Perth, and carries the same first-order administrative seat class. Its recorded population is below Perth's. Against Perth, Malang follows Kota Malang → East Java → Indonesia in the source. Its point has higher latitude and lower longitude; it belongs to the selected Indonesia cohort rather than Australia, uses Asia/Jakarta instead of Australia/Perth, and carries populated place rather than first-order administrative seat. Its recorded population is below Perth's. Its nearest-neighbor distance ranks 1,205 of 1,206 from shortest to longest in the same snapshot. Perth'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 2063523, the coordinate pair 31.9522 / 115.8614, country rank 4 of 7, and neighbor GeoNames 2078025 at 2,130.795 km bind Perth to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Perth's reference point is 31.9522° south and 115.8614° east. The IANA identifier Australia/Perth is shared by 1 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. Perth's row carries both second- and first-order administrative labels. Perth's point falls in the middle-latitude coordinate band used by this atlas's row checks. Perth's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Perth, 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.
