Source identity and administrative path
The source row behind Saint Petersburg is GeoNames ID 498817. Its recorded administrative path is St.-Petersburg → Russia, and GeoNames classifies the place as a first-order administrative seat. Saint Petersburg 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.
Population position inside fixed cohorts
Within the fixed 1,206-record atlas, Saint Petersburg ranks 54 by recorded population. Inside the 39 selected Russia entries it ranks 2; inside the 125 entries in its broad region it ranks 3. Its 5,351,935 population value is 8.26 times the 648,213 median for the country cohort and 8.06 times the 664,046 regional median. Saint Petersburg falls inside the leading tenth of this atlas's Russia population cohort. Saint Petersburg'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
Saint Petersburg's three nearest other atlas coordinates are Helsinki at 299.57 km with 658,864 recorded people; Riga at 490.818 km with 742,572 recorded people; Yaroslavl at 607.046 km with 608,722 recorded people. The closest-to-farthest distance spread is 307.476 km. Compared with Helsinki, Saint Petersburg's recorded population is 8.12 times as large. Against Saint Petersburg, Helsinki follows Helsinki sub-region → Uusimaa → Finland in the source. Its point has higher latitude and lower longitude; it belongs to the selected Finland cohort rather than Russia, uses Europe/Helsinki instead of Europe/Moscow, and carries capital of a political entity rather than first-order administrative seat. Its recorded population is below Saint Petersburg's. Against Saint Petersburg, Riga follows Riga → Latvia in the source. Its point has lower latitude and lower longitude; it belongs to the selected Latvia cohort rather than Russia, uses Europe/Riga instead of Europe/Moscow, and carries capital of a political entity rather than first-order administrative seat. Its recorded population is below Saint Petersburg's. Against Saint Petersburg, Yaroslavl follows Yaroslavl Oblast → Russia in the source. Its point has lower latitude and higher longitude; it belongs to the same selected Russia cohort, uses the shared Europe/Moscow identifier, and carries the same first-order administrative seat class. Its recorded population is below Saint Petersburg's. Its nearest-neighbor distance ranks 1,111 of 1,206 from shortest to longest in the same snapshot. Saint Petersburg'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 498817, the coordinate pair 59.9386 / 30.3141, country rank 2 of 39, and neighbor GeoNames 658225 at 299.57 km bind Saint Petersburg 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
Saint Petersburg's reference point is 59.9386° north and 30.3141° east. The IANA identifier Europe/Moscow is shared by 15 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. Saint Petersburg's row carries a first-order administrative label but no second-order label. Saint Petersburg's point falls in the higher-latitude coordinate band used by this atlas's row checks. Saint Petersburg's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Saint Petersburg, 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.
