Source identity and administrative path
The source row behind Rome is GeoNames ID 3169070. Its recorded administrative path is Citta metropolitana di Roma Capitale → Lazio → Italy, and GeoNames classifies the place as a capital of a political entity. Rome 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 2025-07-22; 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, Rome ranks 168 by recorded population. Inside the 8 selected Italy entries it ranks 1; inside the 125 entries in its broad region it ranks 7. Its 2,318,895 population value is 3.10 times the 747,774 median for the country cohort and 3.49 times the 664,046 regional median. Rome is rank 1 among the 8 selected Italy entries, so a percentage band would overstate this small cohort. Rome'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.
Nearest-reference pattern
Rome's three nearest other atlas coordinates are Naples at 186.693 km with 909,048 recorded people; Florence at 233.834 km with 367,150 recorded people; Venice at 394.47 km with 51,298 recorded people. The closest-to-farthest distance spread is 207.777 km. Compared with Naples, Rome's recorded population is 2.55 times as large. Against Rome, Naples follows Napoli → Campania → Italy in the source. Its point has lower latitude and higher longitude; it belongs to the same selected Italy cohort, uses the shared Europe/Rome identifier, and carries first-order administrative seat rather than capital of a political entity. Its recorded population is below Rome's. Against Rome, Florence follows Province of Florence → Tuscany → Italy in the source. Its point has higher latitude and lower longitude; it belongs to the same selected Italy cohort, uses the shared Europe/Rome identifier, and carries first-order administrative seat rather than capital of a political entity. Its recorded population is below Rome's. Against Rome, Venice follows Provincia di Venezia → Veneto → Italy in the source. Its point has higher latitude and lower longitude; it belongs to the same selected Italy cohort, uses the shared Europe/Rome identifier, and carries first-order administrative seat rather than capital of a political entity. Its recorded population is below Rome's. Its nearest-neighbor distance ranks 961 of 1,206 from shortest to longest in the same snapshot. Rome'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 3169070, the coordinate pair 41.8919 / 12.5113, country rank 1 of 8, and neighbor GeoNames 3172394 at 186.693 km bind Rome 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
Rome's reference point is 41.8919° north and 12.5113° east. The IANA identifier Europe/Rome is shared by 8 city rows in this catalog, while the GeoNames class PPLC is shared by 129 rows. Rome's row carries both second- and first-order administrative labels. Rome's point falls in the middle-latitude coordinate band used by this atlas's row checks. Rome's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames records Rome at 20 metres above sea level, a single reference value rather than a description of slopes across the city. Together these fields form a reproducible identity check for this page, not a claim about walkability, climate or accessibility.
