The Decade Appropriations Report is a visual representation of the Budget Estimates of the Federal Republic of Nigeria over a ten-year period; the 2011 Budget was skipped because the data, sourced entirely from a public domain, was not legible enough to be imported for analysis. The data source link and related information are available on the INFO Page of the report.
The 7-page report begins with an OVERVIEW display that provides interactivity and switch between the Capital and Recurrent Expenditure details. The principles and practice of budgeting in Nigeria are explained in the INFORMATION page, which comprises three sub-pages. You are welcome.
