Background: Care needs across countries depend on fertility rates, aging of the population, and the prevalence and causes of morbidity. Method/Disucussion: A care dependency ratio measures future care needs relative to the potential future supply of caregivers. Time-use survey data indicate that future unpaid caregivers will be equivalent to one- to two-fifths of the labor force. • Unless the gender division of family care work changes, women and girls will be providing four-fifths of future unpaid caregiving.
