01What the data says — and does not say
This page separates the checked GeoNames row for Port-au-Prince—1,234,742, America/Port-au-Prince, 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.
02This city's dataset fingerprint
The source row behind Port-au-Prince is GeoNames ID 3718426. Its recorded administrative path is Arrondissement de Port-au-Prince → Ouest → Haiti, and GeoNames classifies the place as a capital of a political entity. Port-au-Prince 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 2019-09-05; 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, Port-au-Prince ranks 422 by recorded population. Inside the 2 selected Haiti entries it ranks 1; inside the 198 entries in its broad region it ranks 58. Its 1,234,742 population value is 1.41 times the 873,044 median for the country cohort and 1.51 times the 816,326 regional median. Port-au-Prince is rank 1 among the 2 selected Haiti entries, so a percentage band would overstate this small cohort. Port-au-Prince's recorded value is above the country-cohort median but remains below twice that benchmark. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.

Port-au-Prince's nearest-coordinate gap belongs to the tightest tenth of the atlas. 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 3718426, the coordinate pair 18.5435 / 72.3388, country rank 1 of 2, and neighbor GeoNames 6201369 at 6.549 km bind Port-au-Prince to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Port-au-Prince's reference point is 18.5435° north and 72.3388° west. The IANA identifier America/Port-au-Prince is shared by 2 city rows in this catalog, while the GeoNames class PPLC is shared by 129 rows. Port-au-Prince's row carries both second- and first-order administrative labels. Port-au-Prince's point falls in the lower-latitude coordinate band used by this atlas's row checks. Port-au-Prince's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Port-au-Prince, 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.
