The Council on Foreign Relations , while explaining the methodology behind the data, said it relied on media reports.

The report said , “ The Nigeria Security Tracker tracks violence that is both causal and symptomatic of Nigeria ’ s political instability and citizen alienation . The data are based on weekly surveys of Nigerian and international media.

“ The data start with May 29 , 2011, the date of Goodluck Jonathan’ s inauguration as president . It was an event that highlighted the increasing bifurcation of the country on regional and religious lines . The NST is updated weekly .

“ Relying on press reports of violence presents methodological limitations.

There is a dearth of accurate reporting across certain regions, death tolls are imprecise, and accounts of incidents vary . There is the potential for political manipulation of media . Given these limitations , the NST makes every effort to collect information from multiple sources . Nevertheless , NST statistics should be viewed as indicative rather than definitive.”
