Treatment of people with disabilities is another major issue facing the country. According to the Lesotho Census of 2006, around four percent of the population is thought to have some sort of disability. However, there are concerns regarding the reliability of the methodologies used and the real figure is thought to be closer to the global estimate of 15 percent. According to a survey conducted by the Lesotho National Federation of Organisations of the Disabled in conjunction with SINTEF, people with disability in Lesotho face significant social and cultural barriers which prevent them from accessing education, healthcare, and employment on an equal basis with others.
