Social scientists from a number of countries explore key principles of feminist enquiry into theoretical perspectives on voluntary and involuntary childlessness; structure, agency, and childlessness; intersectional perspectives; lived experiences; and national perspectives. Among their topics are from deviant choice to feminist issue: a historical analysis of scholarship on voluntary childlessness 1920-2013, whether loneliness and regret are the inevitable outcomes of ageing and childlessness, age identity and never-married childless older women, finding Mr. Right: childfree women's partner preferences, and stigma and childlessness in historical and contemporary Japan.
