Globally, nearly 250 million children between five and 15 years work every day (see Meier, 2006: p.172). Putting a focus on the African continent, it indicates that the survival of one in three children depends on work in the region south of the Sahara (see Bass, 2004: p.4ff). Still, it remains difficult to estimate the proper number of working children, as many countries keep – if at all – partial statistics concerning this issue; approximations might therefore be false and underestimated (see Lavalette & Cunningham 2001: p. 3).
