01What the data says — and does not say
This page separates the checked GeoNames row for Owerri—545,000, Africa/Lagos, 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: city in Nigeria.
02This city's dataset fingerprint
The source row behind Owerri is GeoNames ID 2325330. Its recorded administrative path is Owerri Municipal → Imo State → Nigeria, and GeoNames classifies the place as a first-order administrative seat. Owerri 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, Owerri ranks 1,026 by recorded population. Inside the 30 selected Nigeria entries it ranks 27; inside the 243 entries in its broad region it ranks 214. Its 545,000 population value is 0.59 times the 930,000 median for the country cohort and 0.60 times the 902,588 regional median. Owerri sits in the lower half of this atlas's selected Nigeria entries. Owerri'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.
Owerri's three nearest other atlas coordinates are Aba at 55.862 km with 1,160,000 recorded people; Port Harcourt at 78.558 km with 2,120,000 recorded people; Onitsha at 78.973 km with 1,553,000 recorded people. The closest-to-farthest distance spread is 23.111 km. Compared with Aba, Owerri's recorded population is 0.47 times as large. Against Owerri, Aba follows Aba South → Abia 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 above Owerri's. Against Owerri, Port Harcourt follows Port-Harcourt → Rivers State → Nigeria in the source. Its point has lower 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 Owerri's. Against Owerri, Onitsha follows Onitsha North → Anambra → 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 Owerri's. Its nearest-neighbor distance ranks 480 of 1,206 from shortest to longest in the same snapshot. Owerri'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 2325330, the coordinate pair 5.4836 / 7.0333, country rank 27 of 30, and neighbor GeoNames 2353151 at 55.862 km bind Owerri to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Owerri's reference point is 5.4836° north and 7.0333° 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. Owerri's row carries both second- and first-order administrative labels. Owerri's point falls in the near-equatorial coordinate band used by this atlas's row checks. Owerri's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Owerri, 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.
