Source identity and administrative path
The source row behind Mombasa is GeoNames ID 186301. Its recorded administrative path is Mombasa County → Kenya, and GeoNames classifies the place as a first-order administrative seat. Mombasa 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 2022-09-26; 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, Mombasa ranks 436 by recorded population. Inside the 5 selected Kenya entries it ranks 3; inside the 243 entries in its broad region it ranks 90. Its 1,208,333 population value is 1.00 times the 1,208,333 median for the country cohort and 1.34 times the 902,588 regional median. Mombasa is rank 3 among the 5 selected Kenya entries, so a percentage band would overstate this small cohort. Mombasa'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
Mombasa's three nearest other atlas coordinates are Zanzibar City at 240.144 km with 709,809 recorded people; Dar es Salaam at 310.954 km with 5,383,728 recorded people; Arusha at 339.426 km with 617,631 recorded people. The closest-to-farthest distance spread is 99.282 km. Compared with Zanzibar City, Mombasa's recorded population is 1.70 times as large. Against Mombasa, Zanzibar City follows Mjini → Zanzibar Urban/West → Tanzania in the source. Its point has lower latitude and lower longitude; it belongs to the selected Tanzania cohort rather than Kenya, uses Africa/Dar_es_Salaam instead of Africa/Nairobi, and carries the same first-order administrative seat class. Its recorded population is below Mombasa's. Against Mombasa, Dar es Salaam follows Ilala → Dar es Salaam Region → Tanzania in the source. Its point has lower latitude and lower longitude; it belongs to the selected Tanzania cohort rather than Kenya, uses Africa/Dar_es_Salaam instead of Africa/Nairobi, and carries the same first-order administrative seat class. Its recorded population is above Mombasa's. Against Mombasa, Arusha follows Arusha City → Arusha → Tanzania in the source. Its point has higher latitude and lower longitude; it belongs to the selected Tanzania cohort rather than Kenya, uses Africa/Dar_es_Salaam instead of Africa/Nairobi, and carries the same first-order administrative seat class. Its recorded population is below Mombasa's. Its nearest-neighbor distance ranks 1,050 of 1,206 from shortest to longest in the same snapshot. Mombasa'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 186301, the coordinate pair 4.0547 / 39.6636, country rank 3 of 5, and neighbor GeoNames 148730 at 240.144 km bind Mombasa 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
Mombasa's reference point is 4.0547° south and 39.6636° east. The IANA identifier Africa/Nairobi is shared by 5 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. Mombasa's row carries a first-order administrative label but no second-order label. Mombasa's point falls in the near-equatorial coordinate band used by this atlas's row checks. Mombasa's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Mombasa, 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.
