Jacksonville

Source identity and administrative path

The source row behind Jacksonville is GeoNames ID 4160021. Its recorded administrative path is Duval County → Florida → United States, and GeoNames classifies the place as a second-order administrative seat.

Jacksonville 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 2025-06-25; 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, Jacksonville ranks 546 by recorded population. Inside the 43 selected United States entries it ranks 14; inside the 198 entries in its broad region it ranks 73.

Its 1,009,833 population value is 1.29 times the 780,995 median for the country cohort and 1.24 times the 816,326 regional median. Jacksonville sits in the second quarter of this atlas's United States population cohort.

Jacksonville's recorded value is above the country-cohort median but remains below twice that benchmark. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.

Nearest-reference pattern

Jacksonville's three nearest other atlas coordinates are Atlanta at 458.945 km with 510,823 recorded people; Miami at 526.712 km with 487,014 recorded people; Charlotte at 549.557 km with 911,311 recorded people. The closest-to-farthest distance spread is 90.612 km. Compared with Atlanta, Jacksonville's recorded population is 1.98 times as large. Against Jacksonville, Atlanta follows Fulton County → Georgia → United States in the source. Its point has higher latitude and lower longitude; it belongs to the same selected United States cohort, uses the shared America/New_York identifier, and carries first-order administrative seat rather than second-order administrative seat.

Its recorded population is below Jacksonville's. Against Jacksonville, Miami follows Miami-Dade County → Florida → United States in the source. Its point has lower latitude and higher longitude; it belongs to the same selected United States cohort, uses the shared America/New_York identifier, and carries the same second-order administrative seat class. Its recorded population is below Jacksonville's. Against Jacksonville, Charlotte follows Mecklenburg County → North Carolina → United States in the source.

Its point has higher latitude and higher longitude; it belongs to the same selected United States cohort, uses the shared America/New_York identifier, and carries the same second-order administrative seat class. Its recorded population is below Jacksonville's. Its nearest-neighbor distance ranks 1,173 of 1,206 from shortest to longest in the same snapshot. Jacksonville'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 4160021, the coordinate pair 30.3322 / 81.6557, country rank 14 of 43, and neighbor GeoNames 4180439 at 458.945 km bind Jacksonville 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

Jacksonville's reference point is 30.3322° north and 81.6557° west. The IANA identifier America/New_York is shared by 15 city rows in this catalog, while the GeoNames class PPLA2 is shared by 341 rows. Jacksonville's row carries both second- and first-order administrative labels.

Jacksonville's point falls in the middle-latitude coordinate band used by this atlas's row checks. Jacksonville's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames records Jacksonville at 5 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.
