We did not directly test this in our study, but in the future we hope to zero in on the factors driving these trends. We think that the loneliness Americans are reporting compared to peer nations comes down to limited social safety nets and to cultural norms that prioritize individualism over community.

Individualization carries psychological costs, such as reductions in social connections and support structures, which are correlates of loneliness. Relative to the other nations in our study, Americans have a higher tendency to relocate, which is associated with weak social and community ties.

One of the reasons why we chose countries from across Europe is that they differ dramatically from the U.S. when it comes to social and economic opportunities and social safety nets. Social and economic inequalities likely increase one’s loneliness through undermining one’s ability to meet basic needs. Generous family and work policies likely lessen midlife loneliness through reducing financial pressures and work-family conflict, as well as addressing health and gender inequities.

Our findings on loneliness in conjunction with previous studies on life expectancy, health, well-being and cognition suggest that being middle-aged in America is a risk factor for poor mental and physical health outcomes.
