Before Depok City becomes an age friendly city, an assessment of the eight-dimensional indicators of AFC had been carried out by a team of UI researchers from Center of Ageing Studies in collaboration with the Institute for Survey METER in March 2013. One of the main finding was the presence of the three indicators of AFC in Depok which still lack, they are buildings and open space, housing, and civil participation and employment. The purpose of the study was to assess the public’s opinion on the three indicators of AFC that still lack in Depok. The study shows that the majority of people and government as stakeholder assess that Depok is ready to become AFC as long as supported by the government of Depok City with the good coordination with related institutions for the budget and programs prioritizing the interests of the elderly. Moreover, the existence of Komda (Comission Area) of Elderly Depok City can support the establishment of a friendly city towards the elderly. The community prefers to choose the indicators of buildings and open spaces as a top priority for elderly-friendly city rather than chooses the indicators of housing and civil participation and employment for the elderly people. Therefore, hopefully Depok City Government with related institutions can build the building which is elderly-friendly as well as AFC socialization to the government and private sectors in order to achieve rapid implementation of Depok as an AFC.展开更多
