01What the data says — and does not say
This page separates the checked GeoNames row for Madrid—3,255,944, Europe/Madrid, 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 Madrid is GeoNames ID 3117735. Its recorded administrative path is Provincia de Madrid → Madrid → Spain, and GeoNames classifies the place as a capital of a political entity. Madrid 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 2026-02-23; 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, Madrid ranks 107 by recorded population. Inside the 6 selected Spain entries it ranks 1; inside the 125 entries in its broad region it ranks 5. Its 3,255,944 population value is 4.31 times the 755,663 median for the country cohort and 4.90 times the 664,046 regional median. Madrid is rank 1 among the 6 selected Spain entries, so a percentage band would overstate this small cohort. Madrid's recorded value reaches at least twice the country-cohort median in this snapshot. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.
Madrid's three nearest other atlas coordinates are Zaragoza at 274.111 km with 686,986 recorded people; City of Valencia (Spain) at 302.016 km with 824,340 recorded people; Seville city at 390.347 km with 686,741 recorded people. The closest-to-farthest distance spread is 116.236 km. Compared with Zaragoza, Madrid's recorded population is 4.74 times as large. Against Madrid, Zaragoza follows Provincia de Zaragoza → Aragon → Spain in the source. Its point has higher latitude and higher longitude; it belongs to the same selected Spain cohort, uses the shared Europe/Madrid identifier, and carries first-order administrative seat rather than capital of a political entity. Its recorded population is below Madrid's. Against Madrid, City of Valencia (Spain) follows Provincia de Valencia → Valencia → Spain in the source. Its point has lower latitude and higher longitude; it belongs to the same selected Spain cohort, uses the shared Europe/Madrid identifier, and carries first-order administrative seat rather than capital of a political entity. Its recorded population is below Madrid's. Against Madrid, Seville city follows Provincia de Sevilla → Andalusia → Spain in the source. Its point has lower latitude and lower longitude; it belongs to the same selected Spain cohort, uses the shared Europe/Madrid identifier, and carries first-order administrative seat rather than capital of a political entity. Its recorded population is below Madrid's. Its nearest-neighbor distance ranks 1,094 of 1,206 from shortest to longest in the same snapshot. Madrid'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 3117735, the coordinate pair 40.4165 / 3.7026, country rank 1 of 6, and neighbor GeoNames 3104324 at 274.111 km bind Madrid to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Madrid's reference point is 40.4165° north and 3.7026° west. The IANA identifier Europe/Madrid is shared by 6 city rows in this catalog, while the GeoNames class PPLC is shared by 129 rows. Madrid's row carries both second- and first-order administrative labels. Madrid's point falls in the middle-latitude coordinate band used by this atlas's row checks. Madrid's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Madrid, 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.
