Mariam, approximately 16, in the market in Wa in the Upper West region of Ghana on 28 May 2014. Having completed Grade 5 at school, she says her mother withdrew her about a year ago because she was unhappy with her performance: "My mother said I don't know anything." (Children in Ghana frequently start school late.) Mariam now sells ëchim chimí, a confectionery made from flour, sugar, salt and palm oil. She says she grosses GHS 20.00 - 30.00 (£3.95 - 5.93) per day, selling each item for GHS 0.10 (£0.02), and gives the money she earns to her mother.
