Source identity and administrative path
The source row behind Columbus is GeoNames ID 4509177. Its recorded administrative path is Franklin County → Ohio → United States, and GeoNames classifies the place as a first-order administrative seat. Columbus 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.
Population position inside fixed cohorts
Within the fixed 1,206-record atlas, Columbus ranks 604 by recorded population. Inside the 43 selected United States entries it ranks 18; inside the 198 entries in its broad region it ranks 85. Its 913,175 population value is 1.17 times the 780,995 median for the country cohort and 1.12 times the 816,326 regional median. Columbus sits in the second quarter of this atlas's United States population cohort. Columbus'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
Columbus's three nearest other atlas coordinates are Detroit at 263.589 km with 645,705 recorded people; Indianapolis at 270.474 km with 887,642 recorded people; Louisville at 304.541 km with 624,444 recorded people. The closest-to-farthest distance spread is 40.952 km. Compared with Detroit, Columbus's recorded population is 1.41 times as large. Against Columbus, Detroit follows Wayne County → Michigan → United States in the source. Its point has higher latitude and lower longitude; it belongs to the same selected United States cohort, uses America/Detroit instead of America/New_York, and carries second-order administrative seat rather than first-order administrative seat. Its recorded population is below Columbus's. Against Columbus, Indianapolis follows Marion County → Indiana → United States in the source. Its point has lower latitude and lower longitude; it belongs to the same selected United States cohort, uses America/Indiana/Indianapolis instead of America/New_York, and carries the same first-order administrative seat class. Its recorded population is below Columbus's. Against Columbus, Louisville follows Jefferson County → Kentucky → United States in the source. Its point has lower latitude and lower longitude; it belongs to the same selected United States cohort, uses America/Kentucky/Louisville instead of America/New_York, and carries second-order administrative seat rather than first-order administrative seat. Its recorded population is below Columbus's. Its nearest-neighbor distance ranks 1,084 of 1,206 from shortest to longest in the same snapshot. Columbus'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 4509177, the coordinate pair 39.9612 / 82.9988, country rank 18 of 43, and neighbor GeoNames 4990729 at 263.589 km bind Columbus 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
Columbus's reference point is 39.9612° north and 82.9988° west. The IANA identifier America/New_York is shared by 15 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. Columbus's row carries both second- and first-order administrative labels. Columbus's point falls in the middle-latitude coordinate band used by this atlas's row checks. Columbus's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames records Columbus at 235 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.
