Source identity and administrative path
The source row behind Tbilisi is GeoNames ID 611717. Its recorded administrative path is Tbilisi → Georgia, and GeoNames classifies the place as a capital of a political entity. Tbilisi 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 2026-06-11; 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, Tbilisi ranks 512 by recorded population. Inside the 1 selected Georgia entries it ranks 1; inside the 632 entries in its broad region it ranks 300. Its 1,049,498 population value is 1.00 times the 1,049,498 median for the country cohort and 1.04 times the 1,008,426 regional median. Tbilisi is rank 1 among the 1 selected Georgia entries, so a percentage band would overstate this small cohort. Tbilisi's recorded value stays within one quarter of the country-cohort median used here. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.
Nearest-reference pattern
Tbilisi's three nearest other atlas coordinates are Yerevan at 170.477 km with 1,144,700 recorded people; Makhachkala at 261.681 km with 596,356 recorded people; Erzurum at 359.05 km with 767,848 recorded people. The closest-to-farthest distance spread is 188.573 km. Compared with Yerevan, Tbilisi's recorded population is 0.92 times as large. Against Tbilisi, Yerevan follows Yerevan → Armenia in the source. Its point has lower latitude and lower longitude; it belongs to the selected Armenia cohort rather than Georgia, uses Asia/Yerevan instead of Asia/Tbilisi, and carries the same capital of a political entity class. Its recorded population is above Tbilisi's. Against Tbilisi, Makhachkala follows Dagestan → Russia in the source. Its point has higher latitude and higher longitude; it belongs to the selected Russia cohort rather than Georgia, uses Europe/Moscow instead of Asia/Tbilisi, and carries first-order administrative seat rather than capital of a political entity. Its recorded population is below Tbilisi's. Against Tbilisi, Erzurum follows Erzurum → Türkiye in the source. Its point has lower latitude and lower longitude; it belongs to the selected Türkiye cohort rather than Georgia, uses Europe/Istanbul instead of Asia/Tbilisi, and carries first-order administrative seat rather than capital of a political entity. Its recorded population is below Tbilisi's. Its nearest-neighbor distance ranks 933 of 1,206 from shortest to longest in the same snapshot. Tbilisi'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 611717, the coordinate pair 41.6914 / 44.8341, country rank 1 of 1, and neighbor GeoNames 616052 at 170.477 km bind Tbilisi 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
Tbilisi's reference point is 41.6914° north and 44.8341° east. The IANA identifier Asia/Tbilisi is shared by 1 city rows in this catalog, while the GeoNames class PPLC is shared by 129 rows. Tbilisi's row carries a first-order administrative label but no second-order label. Tbilisi's point falls in the middle-latitude coordinate band used by this atlas's row checks. Tbilisi's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Tbilisi, 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.
