Source identity and administrative path
The source row behind Las Vegas is GeoNames ID 5506956. Its recorded administrative path is Clark County → Nevada → United States, and GeoNames classifies the place as a second-order administrative seat. Las Vegas 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 2025-06-25; 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, Las Vegas ranks 866 by recorded population. Inside the 43 selected United States entries it ranks 31; inside the 198 entries in its broad region it ranks 140. Its 641,903 population value is 0.82 times the 780,995 median for the country cohort and 0.79 times the 816,326 regional median. Las Vegas sits in the lower half of this atlas's selected United States entries. Las Vegas'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.
Nearest-reference pattern
Las Vegas's three nearest other atlas coordinates are Los Angeles at 368.137 km with 3,820,914 recorded people; Mexicali at 395.498 km with 1,032,686 recorded people; Phoenix at 412.411 km with 1,650,070 recorded people. The closest-to-farthest distance spread is 44.274 km. Compared with Los Angeles, Las Vegas's recorded population is 0.17 times as large. Against Las Vegas, Los Angeles follows Los Angeles County → California → United States in the source. Its point has lower latitude and lower longitude; it belongs to the same selected United States cohort, uses the shared America/Los_Angeles identifier, and carries the same second-order administrative seat class. Its recorded population is above Las Vegas's. Against Las Vegas, 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/Los_Angeles, and carries first-order administrative seat rather than second-order administrative seat. Its recorded population is above Las Vegas's. Against Las Vegas, Phoenix follows Maricopa 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 America/Phoenix instead of America/Los_Angeles, and carries first-order administrative seat rather than second-order administrative seat. Its recorded population is above Las Vegas's. Its nearest-neighbor distance ranks 1,156 of 1,206 from shortest to longest in the same snapshot. Las Vegas'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 5506956, the coordinate pair 36.1750 / 115.1372, country rank 31 of 43, and neighbor GeoNames 5368361 at 368.137 km bind Las Vegas 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
Las Vegas's reference point is 36.1750° north and 115.1372° west. The IANA identifier America/Los_Angeles is shared by 9 city rows in this catalog, while the GeoNames class PPLA2 is shared by 341 rows. Las Vegas's row carries both second- and first-order administrative labels. Las Vegas's point falls in the middle-latitude coordinate band used by this atlas's row checks. Las Vegas's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames records Las Vegas at 610 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.
