Abstract: With the increasing aging degree in the national population of China, the age-friendly level of the community has attracted wide attention at home and abroad. This study summarized theoretical connotation and research progress of the age-friendly level of the community, built the evaluation index system based on Maslow's hierarchy theory of needs, and investigated the demand situation of the elderly under the guidance of the social evacuation theory. Four typical communities in Nanjing City were selected for the empirical research. The results showed that age-friendly level of the community was mainly affected by the geographical location, construction time, and community type. The closer to the city center the community was the higher the age-friendly level. The newly constructed community had a higher age-friendly level than the old one. The high-grade commercial community usually had high age-friendly level, while the resettlement community had low age-friendly level. With the increase of age, the activities of the elderly groups were more and more concentrated on the community space, and the elderly's dependence on the community service facilities was increasing. In order to adapt to the deepening aging trend, it is necessary to fully consider the wishes of the elderly group on the basis of the current situation of the age-friendly level of the community.

Key words: aging population, age-friendly communities, Nanjing City
