Senegal has a relatively low childmobility rate (children who leave their parents). Yet,concern has been raised with regards to the vulnerability ofgirls who work as domestic servants and boys who leave tostudy the Koran within informal structures. To learn moreabout their numbers and the reasons why they leave, FafoInstitute for Applied International Studies (Fafo) andl Ecole nationale d economie appliquee (ENEA), supported bythe World Bank trust fund, TFESSD, in 2009, launched a ruralhousehold survey that aimed to quantify child mobilitypractices and identify the features of the households fromwhich the children come. The vulnerability of ruralhouseholds to risks and shocks related to climaticconditions like drought, irregular rainfall, animal diseaseand locust was of special concern. This report presents themain results of this project.
