Santa Tereza do Oeste is a Brazilian municipality in the west region of the state of Paraná. The total population of the municipality, in urban and rural area, is 10.332 inhabitants according to IBGE data (2010). Of these 1144  individuals are aged 60 and over. Aging is a continuous process that requires special and adequate care. Because of this, several actions have been taken in place and many of them have been included in the action plan for the WHO Age Friendly Program. These activities have been carried out in a multisectorial collaboration, including the departments of Social Services and CRAS, Health, Education and Culture department, Urbanization, Sports and Leisure administration. Since the commitment made, in June 2019, it is clear that many of the actions already developed meet the criteria necessary to become an age friendly city and based on quantitative and qualitative research, the action plan was prepared including the wishes and views of the older population. Becoming an Age Friendly City, not only refers to what has already been done or in the city, but it is a commitment that the city is making for the future. It is also a continuity program for the next managers. Much progress has been made to provide that in Santa Tereza do Oeste older people participate in the development of the city as an age friendly environment.
