Current policies on ageing in Ghana seem to be disjointed, and ideas on documents on to improve policies in population ageing have yet to be concretely implemented, perhaps partly because of many arguments that older people are only a small proportion of the population Global ageing populations seem to cause many countries to be increasing the age for old age security from 60 to 65 to decrease the cost of the scheme of the GDP. Age discrimination can be defined as "the systematic and institutionalized denial of the rights of older people on the basis of their age by individuals, groups, organisations, and institutions." Some of the abuse can be a result of ignorance, thoughtlessness, prejudice, and stereotyping. Forms of discrimination are economic accessibility, social accessibility, temporal accessibility and administrative accessibility. In most countries worldwide, particularly countries in Africa, older people are typically the poorest members of the social spectrum and live below the poverty line.
