Standard HEA baselines in Yobe State, northern Nigeria and Zambia were expanded to include data on children’s contribution to the household economy. The child sensitive HEA quantified income earned by children and examined household expenditure on children’s basic needs. Interviews with children led to profiles on children’s work (age first started work; type; frequency; seasonal changes; benefits; disadvantages and risks; how income is spent; and effects of bad years on children’s work. The child sensitive data will be used by Save the Children International to support child-based programming in selected projects.
