Sudan has lost four places in the Index of Human Development going from number 150 to 154 in a list of 169 countries and was placed in the category low human development.
Last year Sudan was among medium human development countries.Norway, Australia and New Zealand occupy the first three places respectively in a list of 43 countries with very high human development while the bottom three are Zimbabwe, the least developed, DR Congo and Niger.
Neighbouring Kenya, Uganda, Ethiopia and Central African Republic are also among low human development countries.
The Index of Human Development is published since 1990 by the United Nations Development Programme (UNDP).
It determines human development through four indicators: life expectancy at birth, mean years of schooling, expected years of schooling and gross national income per head; and three dimensions: health, education and living standards.
The index that covers 168 UN member countries and Hong Kong was released yesterday.
Fourteen countries, including Eritrea, were dropped from the index due to lack of internationally compiled and verified data.
