01What the data says — and does not say
This page separates the checked GeoNames row for Porto—252,687, Europe/Lisbon, 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 seat of Porto district and municipality.
02This city's dataset fingerprint
The source row behind Porto is GeoNames ID 2735943. Its recorded administrative path is Porto → Portugal, and GeoNames classifies the place as a first-order administrative seat. Porto 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, Porto ranks 1,203 by recorded population. Inside the 2 selected Portugal entries it ranks 2; inside the 125 entries in its broad region it ranks 123. Its 252,687 population value is 0.66 times the 385,245 median for the country cohort and 0.38 times the 664,046 regional median. Porto is rank 2 among the 2 selected Portugal entries, so a percentage band would overstate this small cohort. Porto'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.
Porto's three nearest other atlas coordinates are Lisbon at 273.357 km with 517,802 recorded people; Madrid at 421.147 km with 3,255,944 recorded people; Seville city at 476.275 km with 686,741 recorded people. The closest-to-farthest distance spread is 202.918 km. Compared with Lisbon, Porto's recorded population is 0.49 times as large. Against Porto, Lisbon follows Lisbon → Portugal in the source. Its point has lower latitude and lower longitude; it belongs to the same selected Portugal cohort, uses the shared Europe/Lisbon identifier, and carries capital of a political entity rather than first-order administrative seat. Its recorded population is above Porto's. Against Porto, Madrid follows Provincia de Madrid → Madrid → Spain in the source. Its point has lower latitude and higher longitude; it belongs to the selected Spain cohort rather than Portugal, uses Europe/Madrid instead of Europe/Lisbon, and carries capital of a political entity rather than first-order administrative seat. Its recorded population is above Porto's. Against Porto, Seville city follows Provincia de Sevilla → Andalusia → Spain in the source.

Its recorded population is above Porto's. Its nearest-neighbor distance ranks 1,092 of 1,206 from shortest to longest in the same snapshot. Porto'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 2735943, the coordinate pair 41.1485 / 8.6110, country rank 2 of 2, and neighbor GeoNames 2267057 at 273.357 km bind Porto to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Porto's reference point is 41.1485° north and 8.6110° west. The IANA identifier Europe/Lisbon is shared by 2 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. Porto's row carries both second- and first-order administrative labels. Porto's point falls in the middle-latitude coordinate band used by this atlas's row checks. Porto's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Porto, 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.
