The Yearbook assesses whether a media piece explains the root-causes of the problem or issue in the storyline, not other causes about something else. Covering the root causes contributes positively to audience understanding of events. On average, 24% of the units cover root causes. This was the same in 2018. However, there are differences between media genres. Print media still performs best at 27% even though that is a drop of 10 percentage points from 2018. National and local radio recorded 18% and 23%, an improvement of 2 and 3% respectively. TV is stable at 25%. JamiiForums recorded 10%, which shows that a small percentage of debates on the platform focus on the root causes of issues.
