Malaria Cases and Deaths

Malaria’s Worldwide Decline

Malaria deaths are down 48% worldwide between 2000 and 2015, based on data provided by the World Health Organization.  Malaria cases are also down, but only 18%.  Both malaria cases and deaths are now concentrated in Africa.  The rest of the world accounted for 18% of malaria cases in 2000 and now only accounts for 12%.  The charts below summarize the changes:Malaria Cases and Deaths

The two stacked bar charts are formatted to sit next to each other and show how two different measures are applied to the same years and regions.  I made the first 1/2 page chart, formatted it, copied it, and then altered the data and axis title to make the second chart.  In each chart, I chose to summarize the regional data presented by WHO into just two series–Africa and Rest of World.  I think the story in the data is the comparison between Africa and other regions.  Showing the six WHO regions in the chart made it very cluttered and did not add to the message.  I chose to show percentages in each segment and the total for the bar on top to focus on both the absolute changes and the proportional variation over time between Africa and the other regions.  I also added the data column to each chart to display the change percentage by region.  Here is the chart in SlideShare to download and edit using Mekko Graphics:
