Source identity and administrative path
The source row behind Port Sudan is GeoNames ID 377039. Its recorded administrative path is Red Sea → Sudan, and GeoNames classifies the place as a first-order administrative seat. Port Sudan 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, Port Sudan ranks 1,172 by recorded population. Inside the 5 selected Sudan entries it ranks 5; inside the 243 entries in its broad region it ranks 237. Its 489,725 population value is 0.48 times the 1,012,211 median for the country cohort and 0.54 times the 902,588 regional median. Port Sudan is rank 5 among the 5 selected Sudan entries, so a percentage band would overstate this small cohort. Port Sudan'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
Port Sudan's three nearest other atlas coordinates are Jeddah at 292.26 km with 4,697,000 recorded people; Makkah at 338.068 km with 1,578,722 recorded people; Ta'if at 380.637 km with 688,693 recorded people. The closest-to-farthest distance spread is 88.377 km. Compared with Jeddah, Port Sudan's recorded population is 0.10 times as large. Against Port Sudan, Jeddah follows Mecca Region → Saudi Arabia in the source. Its point has higher latitude and higher longitude; it belongs to the selected Saudi Arabia cohort rather than Sudan, uses Asia/Riyadh instead of Africa/Khartoum, and carries populated place rather than first-order administrative seat. Its recorded population is above Port Sudan's. Against Port Sudan, Makkah follows Mecca Region → Saudi Arabia in the source. Its point has higher latitude and higher longitude; it belongs to the selected Saudi Arabia cohort rather than Sudan, uses Asia/Riyadh instead of Africa/Khartoum, and carries the same first-order administrative seat class. Its recorded population is above Port Sudan's. Against Port Sudan, Ta'if follows Mecca Region → Saudi Arabia in the source. Its point has higher latitude and higher longitude; it belongs to the selected Saudi Arabia cohort rather than Sudan, uses Asia/Riyadh instead of Africa/Khartoum, and carries populated place rather than first-order administrative seat. Its recorded population is above Port Sudan's. Its nearest-neighbor distance ranks 1,107 of 1,206 from shortest to longest in the same snapshot. Port Sudan'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 377039, the coordinate pair 19.6175 / 37.2164, country rank 5 of 5, and neighbor GeoNames 105343 at 292.26 km bind Port Sudan 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
Port Sudan's reference point is 19.6175° north and 37.2164° east. The IANA identifier Africa/Khartoum is shared by 5 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. Port Sudan's row carries a first-order administrative label but no second-order label. Port Sudan's point falls in the lower-latitude coordinate band used by this atlas's row checks. Port Sudan's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Port Sudan, 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.
