The latest Corruption Perceptions Index was released last week by Transparency International.
The index gives each country a score between 1 and 100, representing the level of perceived corruption. (It is understandably difficult to measure actual corruption as it usually happens in secret). A higher score is better – ie. it means the level of perceived corruption is lower.
So what does it tell us about countries in East Africa?
The first chart shows how Tanzania, Uganda and Kenya scored, compared with selected other countries from around Africa. The slider at the top of the chart means you can see how the same countries scored in previous years.
Sliding back to 2012, you can see that both Tanzania and Uganda have moved further to the right over the past three years. In other words, other countries have been doing better at addressing corruption than these two.
The second chart shows how CPI scores have changed over these three years, for the same collection of countries.
In both Tanzania and Uganda, CPI scores dropped sharply between 2012 and 2015, putting them down towards the bottom of the chart. Only Malawi lost more CPI points during this period.
Kenya did a little better, but still lost two points over these three years.
The data for the CPI was gathered well before President Magufuli took office in Tanzania. His early moves against corruption have attracted a lot of attention. If he can keep up this momentum, there is a good chance that Tanzania’s CPI score will improve dramatically over the next few years.
