Every row is indexed to the last count complete before the first day in office ("from" marks a start that had to move because that count had no data, or because the period cut it); the province is measured over the same months. Levels are per cent changes, rates are differences in %; "per year" compounds levels and divides rates. Tenures with under 12 months, or under three observations, are left out. ₩tn, constant prices · Statistics Korea gross regional domestic product via the OECD regional database (TL3), constant prices, calendar years dated at mid-year · metropolitan city data · as of Jul 2025.
