Book excerpt: The 2006 edition of UNICEF's annual report focuses on the millions of children who are most in need of access to essential education, health and protection services, but who are also the hardest to reach and often overlooked by current development programmes. These include children living in the poorest countries and most deprived communities within countries, children who face discrimination on the basis of gender, ethnicity or disability, children caught up in armed conflicts or affected by HIV/AIDS, children who lack a formal identity and who suffer from abuse and exploitation. The report examines the factors which result in their exclusion from current child development programmes and services, and highlights the policy options and actions required to address these challenges, in order to ensure all children benefit from the progress being made to achieve the Millennium Development Goals. Topics discussed include: income disparities and child survival, the marginalisation of Roma communities and their children, disability issues, children and HIV/AIDS, children living on the streets, early marriages, child labour, child protection and child rights.
