Jeonbuk State's full administrative territory in the southwest, including the Gogunsan Islands and its other offshore islands. The province became Jeonbuk Special Self-Governing Province (English name Jeonbuk State) on 2024-01-18 without any boundary change, so GADM's polygon, labelled Jeollabuk-do, covers the same ground. Population is resident registration population (주민등록인구) at 2025-12-31 and area is the official administrative-area figure at the same date, both from the Ministry of the Interior and Safety annual report already used for Busan, Incheon, Daegu, Daejeon, Ulsan and Sejong — a different population series from the Statistics Korea register-based census (등록센서스) behind the South Korea and Seoul pages, though the two are usually close. The outline is GADM 4.1's Jeollabuk-do polygon, which measures about 8,095 km² against the official 8,077.65 km² (+0.2%). GADM is licensed for non-commercial use only; Atlas is not commercialised.

A new name, the same land
Older maps and references call it North Jeolla Province (전라북도). The 2024 change created a special self-governing province with the same fourteen cities and counties, so figures from before and after the change describe the same territory.
Its southern neighbour is different: Gwangju and South Jeolla merged on 2026-07-01 into a new unified special city, whose own statistics series has not yet been established. That is why neither Gwangju nor South Jeolla has a page on this site yet.
