Recent research on singlehood shifts from the previous concentration of negative life outcomes
of single status towards a concentration on positive outcomes. Further most studies concerning
singlehood have been performed in North American countries. Therefore exploring factors
related to single people's happiness and the specificity of singlehood in other than North
American countries is becoming increasingly important. The authors utilize the data collected
in the European Social Survey (ESS) in the period of 16 years (2002-2018) to determine the
shares of never-married single adults in Europe and explore various factors associated with the
happiness of single adults across 33 European countries. This monograph shows the review of
definitions of singlehood the rates of single individuals in each of the 33 European countries
and across nine ESS rounds and the socio-demographic profile of singles. It also presents the
results of the analyses concerning the subjective well-being and general health of single
people basic human values and religion.
