This study aims to contribute to the OECD initiative for creating child-friendly neighbourhoods by collecting domestic data based on the concept and monitoring indicators of child-friendly neighbourhoods. It provides policy recommendations to improve the living environment faced by children and address the serious issues Korea faces concerning low birth rates and regional population decline. As policy alternatives, this study recommends: creating a child-friendly environment from a multidimensional perspective, developing local data to support the creation of child-friendly neighbourhoods, promoting the OECD Child-Friendly Neighbourhood pilot project, fostering international cooperation to establish an OECD Child-Friendly Neighbourhood monitoring system, and using spatial geographic information systems for data collection.
