01What the data says — and does not say
This page separates the checked GeoNames row for Phoenix—1,650,070, America/Phoenix, 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 the U.S. state of Arizona and seat of Maricopa County.
02This city's dataset fingerprint
The source row behind Phoenix is GeoNames ID 5308655. Its recorded administrative path is Maricopa County → Arizona → United States, and GeoNames classifies the place as a first-order administrative seat. Phoenix 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 2026-04-14; 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, Phoenix ranks 273 by recorded population. Inside the 43 selected United States entries it ranks 7; inside the 198 entries in its broad region it ranks 36. Its 1,650,070 population value is 2.11 times the 780,995 median for the country cohort and 2.02 times the 816,326 regional median. Phoenix falls between the leading tenth and quarter of this atlas's United States population cohort. Phoenix'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.
Phoenix's three nearest other atlas coordinates are Tucson at 173.488 km with 542,629 recorded people; Mexicali at 328.033 km with 1,032,686 recorded people; Las Vegas at 412.411 km with 641,903 recorded people. The closest-to-farthest distance spread is 238.923 km. Compared with Tucson, Phoenix's recorded population is 3.04 times as large. Against Phoenix, Tucson follows Pima County → Arizona → United States in the source. Its point has lower latitude and higher longitude; it belongs to the same selected United States cohort, uses the shared America/Phoenix identifier, and carries second-order administrative seat rather than first-order administrative seat. Its recorded population is below Phoenix's. Against Phoenix, Mexicali follows Mexicali → Baja California → Mexico in the source. Its point has lower latitude and lower longitude; it belongs to the selected Mexico cohort rather than United States, uses America/Tijuana instead of America/Phoenix, and carries the same first-order administrative seat class. Its recorded population is below Phoenix's. Against Phoenix, Las Vegas follows Clark County → Nevada → United States in the source. Its point has higher latitude and lower longitude; it belongs to the same selected United States cohort, uses America/Los_Angeles instead of America/Phoenix, and carries second-order administrative seat rather than first-order administrative seat. Its recorded population is below Phoenix's. Its nearest-neighbor distance ranks 943 of 1,206 from shortest to longest in the same snapshot. Phoenix'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 5308655, the coordinate pair 33.4484 / 112.0740, country rank 7 of 43, and neighbor GeoNames 5318313 at 173.488 km bind Phoenix to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Phoenix's reference point is 33.4484° north and 112.0740° west. The IANA identifier America/Phoenix is shared by 2 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. Phoenix's row carries both second- and first-order administrative labels. Phoenix's point falls in the middle-latitude coordinate band used by this atlas's row checks. Phoenix's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames records Phoenix at 331 metres above sea level, a single reference value rather than a description of slopes across the city. Together these fields form a reproducible identity check for this page, not a claim about walkability, climate or accessibility.
