01What the data says — and does not say
This page separates the checked GeoNames row for Sydney—5,638,830, Australia/Sydney, 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 New South Wales, Australia.
02This city's dataset fingerprint
The source row behind Sydney is GeoNames ID 2147714. Its recorded administrative path is New South Wales → Australia, and GeoNames classifies the place as a first-order administrative seat. Sydney 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, Sydney ranks 50 by recorded population. Inside the 7 selected Australia entries it ranks 1; inside the 8 entries in its broad region it ranks 1. Its 5,638,830 population value is 2.36 times the 2,384,371 median for the country cohort and 2.87 times the 1,965,786 regional median. Sydney is rank 1 among the 7 selected Australia entries, so a percentage band would overstate this small cohort. Sydney's recorded value reaches at least twice the country-cohort median in this snapshot. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.
Sydney's three nearest other atlas coordinates are Newcastle at 117.104 km with 508,437 recorded people; Gold Coast at 685.986 km with 640,778 recorded people; Melbourne at 713.365 km with 5,435,590 recorded people. The closest-to-farthest distance spread is 596.261 km. Compared with Newcastle, Sydney's recorded population is 11.09 times as large. Against Sydney, 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 the shared Australia/Sydney identifier, and carries second-order administrative seat rather than first-order administrative seat. Its recorded population is below Sydney's. Against Sydney, Gold Coast follows Gold Coast → Queensland → Australia in the source. Its point has higher latitude and higher longitude; it belongs to the same selected Australia cohort, uses Australia/Brisbane instead of Australia/Sydney, and carries populated place rather than first-order administrative seat. Its recorded population is below Sydney's. Against Sydney, Melbourne follows Melbourne → Victoria → Australia in the source. Its point has lower latitude and lower longitude; it belongs to the same selected Australia cohort, uses Australia/Melbourne instead of Australia/Sydney, and carries the same first-order administrative seat class. Its recorded population is below Sydney's. Its nearest-neighbor distance ranks 757 of 1,206 from shortest to longest in the same snapshot. Sydney'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 2147714, the coordinate pair 33.8679 / 151.2073, country rank 1 of 7, and neighbor GeoNames 2155472 at 117.104 km bind Sydney to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Sydney's reference point is 33.8679° south and 151.2073° east. The IANA identifier Australia/Sydney is shared by 2 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. Sydney's row carries a first-order administrative label but no second-order label. Sydney's point falls in the middle-latitude coordinate band used by this atlas's row checks. Sydney's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Sydney, 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.
