In this chapter, we aim to determine whether a “loneliness epidemic” truly exists, while also providing information on available databases in Europe that can be used to evaluate this issue. Loneliness is a real problem with proven personal and social implications, but if we falsely claim that “the wolf is coming to our flock”, it may become a useless concept for scholars and policy makers which might even stop seeing it as something worthy of their attention. We use data from the European Social Survey, an international methodological sound survey, to estimate the current prevalence of loneliness in European countries and compare it with loneliness prevalence in the pre-COVID-19 era. We found on average small changes in total loneliness prevalences and for different age groups, although the youngest and oldest age groups have a higher propensity for change, depending on the country. Based on the data presented in our chapter, the term “loneliness epidemic” is not justified. Two years after the COVID-19 pandemic, loneliness prevalence is very close to the levels observed a decade ago or even lower. However, this does not diminish the significance of loneliness as a public health concern. On the contrary, approximately 20% of the 15+ population in Europe in 2014 and 2023 experience moderate levels of loneliness, with the highest prevalences in the youngest and oldest (80+) age groups. Between 4 and 15% of the population is severely lonely, with highest prevalences among the oldest age groups in 2014 and 2023.
