Rendall MS, Joshi H, Oh J, Verropoulou G. Comparing the childrearing lifetimes of Britain's 'divorce-revolution' men and women. European Journal of Population / Revue Europeenne de Demographie 2001; 17 (4): 365-388.

British men and women who became parents in the 1960s and 1970s were about to experience a new regime of marital instability. The effect of this on the balance between menís and womenís contributions to childrearing is potentially very large. This study estimates the co-residential foundations of the new gender balance, focusing on the measurement of lifetime number of years of living with dependent-aged children. A variant of the family-status life table is used to combine two data sources: census panel observations of family status across three points ten years apart, and survey data on the years between censuses. One-quarter of women who became parents in the 1960s, and one-third of women who became parents in the 1970s, have been or will be a lone mother at some point. Lone parenthood is the main way in which womenís childrearing lifetimes differ from menís, with seven and eight years respectively of lone motherhood per ever-lone-mother of the 1960s and 1970s parenting cohorts. Menís lone-father years and greater numbers of years spent in second families together provide an average of two years offset against womenís lone-mother years.
