Despite the worldwide increase in unpartnered individuals (i.e., singles), little research exists to provide a comprehensive understanding of the heterogeneity within this population. In the present research (N = 3,195), we drew on the fundamental social motives framework to provide a theory-based description and understanding of different “types” of single individuals. Across two Western samples (primarily European and American) and one Korean sample (all collected during the COVID-19 pandemic in 2020–2021), we identified three groups of singles with relatively consistent motivational patterns: (a) singles with strong independence motives and little interest in affiliation, mating, or status (i.e., independent profile); (b) singles with great interest in self-protection as well as social connections and status (i.e., socially focused profile); and (c) singles with little interest in self-protection but moderate interest in affiliation (i.e., low safety focus profile). Notably, these profile features did not perfectly replicate in one smaller Western sample collected before the pandemic (particularly the low safety focus profile), highlighting the need to interpret the data with the historical background in mind. Across samples, the independence-oriented group of singles consistently reported greater satisfaction with singlehood compared to other groups. The three groups of singles also showed substantial differences in other affective and behavioral variables (e.g., how they spend their social time). These findings advance the growing body of research on singlehood by offering new theoretical perspectives on different types of singles.
