Numbers of the Year Part One

Russian Trolls, a president’s false claims and the amount of Nigerian households that don’t have access to clean drinking water; these all feature in this first instalment of our numbers of the year. We speak to Ben Nimmo, information defence fellow at Atlantic Council’s Digital Defence Lab, Heather Long, the economics correspondent at the Washington Post and Allwell Okpi, researcher and journalist with Africa Check about why they’ve chosen these numbers and why they matter.Presenter: Lizzy McNeill Producer: Lizzy McNeill(Image: Montage of numbers.
