Source identity and administrative path
The source row behind Detroit is GeoNames ID 4990729. Its recorded administrative path is Wayne County → Michigan → United States, and GeoNames classifies the place as a second-order administrative seat. Detroit 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, Detroit ranks 861 by recorded population. Inside the 43 selected United States entries it ranks 30; inside the 198 entries in its broad region it ranks 138. Its 645,705 population value is 0.83 times the 780,995 median for the country cohort and 0.79 times the 816,326 regional median. Detroit sits in the lower half of this atlas's selected United States entries. Detroit'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
Detroit's three nearest other atlas coordinates are Columbus at 263.589 km with 913,175 recorded people; Hamilton at 280.069 km with 569,353 recorded people; Brampton at 306.082 km with 656,480 recorded people. The closest-to-farthest distance spread is 42.493 km. Compared with Columbus, Detroit's recorded population is 0.71 times as large. Against Detroit, Columbus follows Franklin County → Ohio → United States in the source. Its point has lower latitude and higher longitude; it belongs to the same selected United States cohort, uses America/New_York instead of America/Detroit, and carries first-order administrative seat rather than second-order administrative seat. Its recorded population is above Detroit's. Against Detroit, Hamilton follows Hamilton → Ontario → Canada in the source. Its point has higher latitude and higher longitude; it belongs to the selected Canada cohort rather than United States, uses America/Toronto instead of America/Detroit, and carries populated place rather than second-order administrative seat. Its recorded population is below Detroit's. Against Detroit, Brampton follows Peel → Ontario → Canada in the source. Its point has higher latitude and higher longitude; it belongs to the selected Canada cohort rather than United States, uses America/Toronto instead of America/Detroit, and carries populated place rather than second-order administrative seat. Its recorded population is above Detroit's. Its nearest-neighbor distance ranks 1,084 of 1,206 from shortest to longest in the same snapshot. Detroit'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 4990729, the coordinate pair 42.3314 / 83.0458, country rank 30 of 43, and neighbor GeoNames 4509177 at 263.589 km bind Detroit 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
Detroit's reference point is 42.3314° north and 83.0458° west. The IANA identifier America/Detroit is shared by 1 city rows in this catalog, while the GeoNames class PPLA2 is shared by 341 rows. Detroit's row carries both second- and first-order administrative labels. Detroit's point falls in the middle-latitude coordinate band used by this atlas's row checks. Detroit's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames records Detroit at 183 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.
