Adelaide

Source identity and administrative path

The source row behind Adelaide is GeoNames ID 2078025. Its recorded administrative path is Adelaide → South Australia → Australia, and GeoNames classifies the place as a first-order administrative seat.

Adelaide 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.

Population position inside fixed cohorts

Within the fixed 1,206-record atlas, Adelaide ranks 327 by recorded population. Inside the 7 selected Australia entries it ranks 5; inside the 8 entries in its broad region it ranks 6.

Its 1,469,163 population value is 0.62 times the 2,384,371 median for the country cohort and 0.75 times the 1,965,786 regional median. Adelaide is rank 5 among the 7 selected Australia entries, so a percentage band would overstate this small cohort.

Adelaide'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

Adelaide's three nearest other atlas coordinates are Melbourne at 653.733 km with 5,435,590 recorded people; Sydney at 1,162.067 km with 5,638,830 recorded people; Newcastle at 1,235.325 km with 508,437 recorded people. The closest-to-farthest distance spread is 581.592 km. Compared with Melbourne, Adelaide's recorded population is 0.27 times as large. Against Adelaide, Melbourne follows Melbourne → Victoria → Australia in the source. Its point has lower latitude and higher longitude; it belongs to the same selected Australia cohort, uses Australia/Melbourne instead of Australia/Adelaide, and carries the same first-order administrative seat class.

Its recorded population is above Adelaide's. Against Adelaide, Sydney follows New South Wales → Australia in the source. Its point has higher latitude and higher longitude; it belongs to the same selected Australia cohort, uses Australia/Sydney instead of Australia/Adelaide, and carries the same first-order administrative seat class. Its recorded population is above Adelaide's. Against Adelaide, Newcastle follows Newcastle → New South Wales → Australia in the source.

Its point has higher latitude and higher longitude; it belongs to the same selected Australia cohort, uses Australia/Sydney instead of Australia/Adelaide, and carries second-order administrative seat rather than first-order administrative seat. Its recorded population is below Adelaide's. Its nearest-neighbor distance ranks 1,192 of 1,206 from shortest to longest in the same snapshot. Adelaide'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 2078025, the coordinate pair 34.9287 / 138.5986, country rank 5 of 7, and neighbor GeoNames 2158177 at 653.733 km bind Adelaide 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

Adelaide's reference point is 34.9287° south and 138.5986° east. The IANA identifier Australia/Adelaide is shared by 1 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. Adelaide's row carries both second- and first-order administrative labels.

Adelaide's point falls in the middle-latitude coordinate band used by this atlas's row checks. Adelaide's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Adelaide, 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.
