    About the data

    Each region page shows four views: population by 5-year age group with year-on-year change, population by sex, one-person households by single year of age, and how each single year of age has changed over the last five years. Choose a province and its cities and counties are drawn alongside it; choose a city and you get its neighborhoods.

    The figures come from the Resident Registration statistics published each month by the Ministry of the Interior and Safety. They count Korean nationals registered at an address, so they are a de jure count of residents rather than a census estimate, and foreign residents are not included. Because the data are public and the population structure is the starting point of any survey design, we share them as they are, updated at the beginning of each month.

    Korea's local administration has three tiers, and you can follow all of them here:

    Provinces and major cities
    Gyeonggi-do, Jeju-do, Seoul, Busan.
    Cities, counties, and districts
    Suwon-si, Yangyang-gun, Jongno-gu. Bigger cities are divided again into gu.
    Towns, townships, and neighborhoods
    The smallest units shown here: -eup, -myeon, and -dong. These are administrative dong, the units local offices serve, not the legal-status dong used in postal addresses.

    Suffixes such as -do, -si, and -gu are part of the Korean name and we keep them as the official romanization has them. They do not mark the tier: -si appears at all three, and the biggest cities drop it (Seoul, not Seoul-si).

    Where administrative units were merged, split, or renamed, we join the series by name so that comparisons with last year and five years ago continue.
