BACKGROUND OF THE STUDY
Physical disability is very unpredictable because once vibrant able-bodied person can become physically disabled overnight due to an accident or as a result of the side effect of treatment of an illness (Sadiq, 2014). An estimated 10% of every population is likely to be disabled, and up to one in five of the world’s poorest has a disability (Mont, 2007). For reasons such as these, the UN Convention on the Rights and Persons With Disabilities (PWD) adopted on the 13th of December, 2006 estimates that the day to day life of around 25% of the world’s population is affected by disability (UN, 2015). A preamble to the World Health Organization report on disability estimated that 600 million to 650 million persons making 10% of the total world populations of whom approximately 80% live in developing countries, are persons living with various forms of disabilities or impairments. This reduces their ability to effectively or safely use many building facilities (Organization, 2007).’
Nigeria is estimated to have a population of 169 million; although it is argued that the country had not had any credible census since 1816 (UN, 2015).Based on the World Report on Disability, approximately 25 million Nigerians have a disability, with 3.5 million of these having very significant difficulties in social and physical functioning.
