Loneliness is a severe risk factor that has been linked to diminished health outcomes and low quality of life across ages. Young adults have been identified as a high-risk group for experiencing loneliness, but only a few studies have explored the economic and social determinants of loneliness in this age group. Taking a social inequality approach to health, with loneliness as a focus, this study examined: (a) the associations between the following factors - subjective social status (SSS) indicators (perceived poverty and perceived income adequacy), offline and online social capital, and neighbourhood capital - and loneliness; and (2) whether social and neighbourhood capital were moderators in the association between SSS and loneliness. Cross-sectional data for individuals aged 20-29 were taken from the 2017 Israeli Social Survey (N = 1,508). Employing multinomial logit models, we found that perceived poverty was a strong predictor of loneliness. Greater social and neighbourhood capital decreased loneliness, whereas a higher use of online social networks increased loneliness. Neighbourhood capital and perceived trust were moderators, whereas trust was a resilience factor, neighbourhood capital strengthened the negative effect of perceived poverty on loneliness. To reduce the prevalence of loneliness in young adults, policymakers should examine various means of enhancing social and neighbourhood capital along with moderating the use of online social networks. However, they should be aware that interventions of this kind can do little to buffer the strong effect of perceived poverty on loneliness, as in most cases the effect of perceived poverty on the probability of loneliness is not ameliorated by improved social or neighbourhood resources.
