Kinlessness at older ages: Prevalence and heterogeneity in 27 countries

Availability of kin has profound effects on the lives of people, especially in later life when social networks tend to be composed prevalently of family members, and care needs increase. Using data from the last wave (wave 8; 2019-2020) of the Survey of Health, Ageing and Retirement in Europe (SHARE), we estimate the prevalence of kinlessness (i.e., absence of close kin) among older adults aged 65 and more in 27 countries. We consider different definitions of kinlessness, from a less restrictive (i.e., based only on the absence of both partner and children) to a more restrictive one (based also on the absence of grandchildren, parents and siblings). Results show a large variation of kinlessness across countries. The proportion of adults aged 65 and above who lack both a partner and children range between 2-3.5% in Czech Republic, Romania, Israel, and Bulgaria, and more than 8% in Switzerland, Spain, Belgium and Malta. The percentage of older people lacking all considered kin ranges from 0.1 to 4.1%. In addition, in some countries there is a substantial heterogeneity in kinlessness by age and sex. Differences by education are, instead, rare. Understanding the prevalence of older individuals without close kin is critical for policymakers and healthcare providers to design appropriate support systems for this particularly vulnerable group of older people and their possibly unmet care needs.
