Source identity and administrative path
The source row behind Osogbo is GeoNames ID 2325590. Its recorded administrative path is Osogbo → Osun State → Nigeria, and GeoNames classifies the place as a first-order administrative seat. Osogbo 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, Osogbo ranks 862 by recorded population. Inside the 30 selected Nigeria entries it ranks 23; inside the 243 entries in its broad region it ranks 177. Its 645,000 population value is 0.69 times the 930,000 median for the country cohort and 0.71 times the 902,588 regional median. Osogbo sits in the lower half of this atlas's selected Nigeria entries. Osogbo's recorded value is materially below 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
Osogbo's three nearest other atlas coordinates are Ile Ife at 32.097 km with 560,000 recorded people; Oyo at 69.422 km with 736,072 recorded people; Ilorin at 80.7 km with 1,080,000 recorded people. The closest-to-farthest distance spread is 48.603 km. Compared with Ile Ife, Osogbo's recorded population is 1.15 times as large. Against Osogbo, Ile Ife follows Ife Central → Osun State → Nigeria in the source. Its point has lower latitude and higher longitude; it belongs to the same selected Nigeria cohort, uses the shared Africa/Lagos identifier, and carries second-order administrative seat rather than first-order administrative seat. Its recorded population is below Osogbo's. Against Osogbo, Oyo follows Oyo West → Oyo State → Nigeria in the source. Its point has higher latitude and lower longitude; it belongs to the same selected Nigeria cohort, uses the shared Africa/Lagos identifier, and carries second-order administrative seat rather than first-order administrative seat. Its recorded population is above Osogbo's. Against Osogbo, Ilorin follows Ilorin East → Kwara State → Nigeria in the source. Its point has higher latitude and lower longitude; it belongs to the same selected Nigeria cohort, uses the shared Africa/Lagos identifier, and carries the same first-order administrative seat class. Its recorded population is above Osogbo's. Its nearest-neighbor distance ranks 331 of 1,206 from shortest to longest in the same snapshot. Osogbo's nearest-coordinate gap sits in the second quarter 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 2325590, the coordinate pair 7.7710 / 4.5570, country rank 23 of 30, and neighbor GeoNames 2338900 at 32.097 km bind Osogbo 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
Osogbo's reference point is 7.7710° north and 4.5570° east. The IANA identifier Africa/Lagos is shared by 30 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. Osogbo's row carries both second- and first-order administrative labels. Osogbo's point falls in the near-equatorial coordinate band used by this atlas's row checks. Osogbo's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Osogbo, 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.
