01What the data says — and does not say
This page separates the checked GeoNames row for Zanzibar City—709,809, Africa/Dar_es_Salaam, 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 Tanzania.
02This city's dataset fingerprint
The source row behind Zanzibar City is GeoNames ID 148730. Its recorded administrative path is Mjini → Zanzibar Urban/West → Tanzania, and GeoNames classifies the place as a first-order administrative seat. Zanzibar 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, Zanzibar City ranks 776 by recorded population. Inside the 6 selected Tanzania entries it ranks 4; inside the 243 entries in its broad region it ranks 161. Its 709,809 population value is 0.96 times the 737,494 median for the country cohort and 0.79 times the 902,588 regional median. Zanzibar City is rank 4 among the 6 selected Tanzania entries, so a percentage band would overstate this small cohort. Zanzibar City'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.
Zanzibar City's three nearest other atlas coordinates are Dar es Salaam at 73.764 km with 5,383,728 recorded people; Mombasa at 240.144 km with 1,208,333 recorded people; Dodoma at 382.337 km with 765,179 recorded people. The closest-to-farthest distance spread is 308.573 km. Compared with Dar es Salaam, Zanzibar City's recorded population is 0.13 times as large. Against Zanzibar City, Dar es Salaam follows Ilala → Dar es Salaam Region → Tanzania in the source. Its point has lower latitude and higher longitude; it belongs to the same selected Tanzania cohort, uses the shared Africa/Dar_es_Salaam identifier, and carries the same first-order administrative seat class. Its recorded population is above Zanzibar City's. Against Zanzibar City, Mombasa follows Mombasa County → Kenya in the source. Its point has higher latitude and higher longitude; it belongs to the selected Kenya cohort rather than Tanzania, uses Africa/Nairobi instead of Africa/Dar_es_Salaam, and carries the same first-order administrative seat class. Its recorded population is above Zanzibar City's. Against Zanzibar City, Dodoma follows Dodoma Urban District → Dodoma → Tanzania in the source. Its point has lower latitude and lower longitude; it belongs to the same selected Tanzania cohort, uses the shared Africa/Dar_es_Salaam identifier, and carries capital of a political entity rather than first-order administrative seat. Its recorded population is above Zanzibar City's. Its nearest-neighbor distance ranks 581 of 1,206 from shortest to longest in the same snapshot. Zanzibar City'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 148730, the coordinate pair 6.1639 / 39.1979, country rank 4 of 6, and neighbor GeoNames 160263 at 73.764 km bind Zanzibar City to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Zanzibar City's reference point is 6.1639° south and 39.1979° east. The IANA identifier Africa/Dar_es_Salaam is shared by 6 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. Zanzibar City's row carries both second- and first-order administrative labels. Zanzibar City's point falls in the near-equatorial coordinate band used by this atlas's row checks. Zanzibar City's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Zanzibar City, 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.
