ABUJA — Vice President Kashim Shettima has called for a credible national census and shared data standards across government agencies. Speaking through a representative at the 50th anniversary conference of the Chartered Institute of Statisticians of Nigeria, he noted that the last census was conducted in 2006 and said the informal economy and agriculture are poorly measured. Finance Minister Taiwo Oyedele stressed the importance of reliable statistics for budget planning. The institute's president, Godday Ebuh, asked for statistics to be taught in secondary schools.
