Several barriers to social inclusion have over a long period of time been in existence, and therefore the society has all along been striving to overcome these barriers with a view to fully achieving social inclusion in societies. Reduction of these barriers to social inclusion has therefore called for integrated efforts across non-governmental and governmental organizations at all levels, vertically and horizontally in the practice and influencing of policy by direct links to individual people’s experience (Avramov et al. 2002, p. 271).
The social exclusion condition persists and exists in societies simply because of the barriers to social inclusion which have subjected people to numerous difficulties or obstacles that have impeded them from gaining access to crucial elements vital to the realization or achievement of social inclusion. These barriers have generally been characterized into various categories like for instance, social, economic, financial, amenity, information and embedded barriers. It has been ascertained that barriers for socially excluded individuals are at most times intrinsically linked and thus portraying a condition of complex and multiple needs. The social inclusion theory has been greatly attributed to the social policy in a different perspective by acknowledging that a person’s participation in a community or society and the outcomes of life can be mired with numerous barriers, which can either be social, informational, financial or embedded and that such barriers can be interrelated.
