Childhood mortality rates differ for boys and girls.
IT MIGHT be thought that in poor countries, girls would live harder lives than boys. It is true that they can be less well treated within the family and often go to school for shorter periods (though most at least go to school). But child-mortality figures show a more complex picture. In Africa childhood mortality among boys is far higher than among girls, according to new figures from UNICEF that break down mortality by sex for the first time.
