Source identity and administrative path
The source row behind Calumbo is GeoNames ID 2242906. Its recorded administrative path is Bengo → Angola, and GeoNames classifies the place as a second-order administrative seat. Calumbo 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 2026-05-12; 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, Calumbo ranks 852 by recorded population. Inside the 14 selected Angola entries it ranks 8; inside the 243 entries in its broad region it ranks 176. Its 652,270 population value is 1.00 times the 654,033 median for the country cohort and 0.72 times the 902,588 regional median. Calumbo sits in the lower half of this atlas's selected Angola entries. Calumbo'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.

The closest-to-farthest distance spread is 5.219 km. Compared with Viana, Calumbo's recorded population is 0.75 times as large. Against Calumbo, Viana follows Luanda → Angola in the source. Its point has higher latitude and lower longitude; it belongs to the same selected Angola cohort, uses the shared Africa/Luanda identifier, and carries the same second-order administrative seat class. Its recorded population is above Calumbo's. Against Calumbo, Camama follows Luanda → Angola in the source. Its point has higher latitude and lower longitude; it belongs to the same selected Angola cohort, uses the shared Africa/Luanda identifier, and carries the same second-order administrative seat class. Its recorded population is above Calumbo's. Against Calumbo, Mulenvos follows Luanda → Angola in the source. Its point has higher latitude and lower longitude; it belongs to the same selected Angola cohort, uses the shared Africa/Luanda identifier, and carries the same second-order administrative seat class. Its recorded population is above Calumbo's. Its nearest-neighbor distance ranks 307 of 1,206 from shortest to longest in the same snapshot. Calumbo'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 2242906, the coordinate pair 9.1469 / 13.4194, country rank 8 of 14, and neighbor GeoNames 2236500 at 27.28 km bind Calumbo 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
Calumbo's reference point is 9.1469° south and 13.4194° east. The IANA identifier Africa/Luanda is shared by 14 city rows in this catalog, while the GeoNames class PPLA2 is shared by 341 rows. Calumbo's row carries a first-order administrative label but no second-order label. Calumbo's point falls in the near-equatorial coordinate band used by this atlas's row checks. Calumbo's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Calumbo, 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.
