Source identity and administrative path
The source row behind N'Djamena is GeoNames ID 2427123. Its recorded administrative path is N'Djamena → Chad, and GeoNames classifies the place as a capital of a political entity. N'Djamena 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 2023-11-29; 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, N'Djamena ranks 367 by recorded population. Inside the 1 selected Chad entries it ranks 1; inside the 243 entries in its broad region it ranks 72. Its 1,359,526 population value is 1.00 times the 1,359,526 median for the country cohort and 1.51 times the 902,588 regional median. N'Djamena is rank 1 among the 1 selected Chad entries, so a percentage band would overstate this small cohort. N'Djamena'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
N'Djamena's three nearest other atlas coordinates are Maiduguri at 207.31 km with 1,110,000 recorded people; Gombe at 468.672 km with 560,000 recorded people; Bauchi at 601.353 km with 693,700 recorded people. The closest-to-farthest distance spread is 394.043 km. Compared with Maiduguri, N'Djamena's recorded population is 1.22 times as large. Against N'Djamena, Maiduguri follows Maiduguri → Borno State → Nigeria in the source. Its point has lower latitude and lower longitude; it belongs to the selected Nigeria cohort rather than Chad, uses Africa/Lagos instead of Africa/Ndjamena, and carries first-order administrative seat rather than capital of a political entity. Its recorded population is below N'Djamena's. Against N'Djamena, Gombe follows Gombe → Gombe State → Nigeria in the source. Its point has lower latitude and lower longitude; it belongs to the selected Nigeria cohort rather than Chad, uses Africa/Lagos instead of Africa/Ndjamena, and carries first-order administrative seat rather than capital of a political entity. Its recorded population is below N'Djamena's. Against N'Djamena, Bauchi follows Bauchi → Nigeria in the source. Its point has lower latitude and lower longitude; it belongs to the selected Nigeria cohort rather than Chad, uses Africa/Lagos instead of Africa/Ndjamena, and carries first-order administrative seat rather than capital of a political entity. Its recorded population is below N'Djamena's. Its nearest-neighbor distance ranks 1,013 of 1,206 from shortest to longest in the same snapshot. N'Djamena'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 2427123, the coordinate pair 12.1067 / 15.0444, country rank 1 of 1, and neighbor GeoNames 2331447 at 207.31 km bind N'Djamena 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
N'Djamena's reference point is 12.1067° north and 15.0444° east. The IANA identifier Africa/Ndjamena is shared by 1 city rows in this catalog, while the GeoNames class PPLC is shared by 129 rows. N'Djamena's row carries a first-order administrative label but no second-order label. N'Djamena's point falls in the near-equatorial coordinate band used by this atlas's row checks. N'Djamena's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for N'Djamena, 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.
