This paper examines the relationship between informal care and ending paid work for working women of three age groups (up to 30, 31–49 and 50 or more years) in 1995 in Belgium. It explores the effect of being a carer for older adults on the probability of ceasing to work. Most particularly, it focuses on the effect of the care intensity in the different age groups. The analyses use data from the European Community Household Panel (ECHP). A sample of 24,592 working women living in 11 European countries was followed from 1995 to 2001.
