The proportion of elderly people in the society is constantly growing. The elderly who live alone form one of the most vulnerable groups in the society that is also at considerable risk for poverty and social isolation. According to the last population census in Estonia (2011), 39.3% of the elderly (65+) lived alone. The ageing of the population is accompanied by novel challenges, among them especially the coping of the elderly living alone. In 2015, the research team at the Tallinn University School of Governance, Law and Society conducted a study to map Estonian community-based practices that are available for the elderly (65+), especially for those who live alone at home, and the way these practices support interdependent coping and prevent the need for institutional care. This study, based on qualitative and quantitative data collected in Estonian communities, suggests that cooperation between Estonian local governments and communities should be more effective and involve regular interaction. Promising practices include developing network-based community support models and broadening communication possibilities.
