With the emergence of the aging population in China and the relaxation of the three-child policy, children’s issues have garnered continuous attention in society. In recent years, the urban development of China has gradually entered a “stock renewal” optimization stage, and the renovation of old residential compounds has become a significant urban proposition. The residential environment problems in Dongguan’s old residential compounds have become increasingly prominent, and the demand for children’s activity spaces presents complex and diverse challenges. Based on this, this paper, from the perspective of child-friendliness, takes Dongguan’s old residential compounds as the research object, conducting field research and data analysis to explore the supply-demand relationship of children’s activity spaces in these areas.
