The Census is the most credible source of information on demography (population characteristics), economic activity, literacy and education, housing and household facilities, urbanisation, fertility and mortality, tribes, language, religion, migration, disability and many other socio-cultural and demographic data since 1901. The 2015 Census will be the sixth national Census of the country. It is the only source of primary data at the village, town and ward level. It provides valuable information for planning and formulation policies for the Government and is widely used by national and international agencies, scholars, businesses, industrialists, and many more.
