Abstract: The contradiction between supply and demand of urban senior living facilities, as a kind of basic public service resource, is especially severe. A refined population grid obtained by state-of-the-art geographic information technology is required to discover the spatial contradiction. This paper took Pudong New District of Shanghai as the research area. The contradiction between the supply and demand of senior living facilities was revealed based on a refined age population grid at a 160-meter resolution, considering the location of facilities, the number of beds, and the health condition of the elderly. The results show that:The refined age population grid can fully illustrate the spatial attributes of the aged population and can be matched with the distribution of beds in senior living facilities spatially, depicting both the supply and demand of senior living facilities visually. The number of beds in senior living facilities meets the requirements of the Shanghai government, namely no less than 3% of the local registered elderly population. The contradiction between supply and demand of senior living facilities depends on location. A distinctive shortage of supply exists in the central area. Smaller facilities and a dense elderly population reflect an urgent demand. Meanwhile, the situation is the reverse in the suburbs, there are multiple overlapping services of facilities. Some facilities in the outer suburbs are too remote to fit the required demand based on the distribution of the elderly population.
