The document discusses how persons with disabilities have largely been left out of efforts to achieve the Millennium Development Goals. While some goals have led to improvements, the targets do not specifically address the needs of persons with disabilities in places like sub-Saharan Africa and South Asia. As a result, individuals with disabilities are among the poorest members of society with little means of survival. The document calls for disability issues to be more fully incorporated into development strategies and notes that the inherent flaws of only focusing on averages risks leaving the world's most marginalized populations, including those with disabilities, behind.
