Tracking Growth with a Marimekko Chart and Cascade Chart
Here is a charting example using a cascade chart and a Marimekko Chart from the Bain and Company white paper last year The Great Eight: Trillion-Dollar Growth Trends to 2020. The charts below answer two questions:
- How much will the world'a population grow between 2010 and 2020?
- Which countries will contribute most to the growth?
Two-thirds of the population growth in the global middle class will come from just China and India
The cascade chart shows how much the population will grow and it gives you a sense of how large this growth is relative to the 2010 population. The Marimekko chart shows that growth is mostly in Asia-Pacific. Within Asia-Pacific, growth is predominately from India and China. The red shading adds emphasis to the point.
The authors could have driven home the point with a single bar 100% stacked bar chart instead of the Marimekko chart. The Marimekko chart allows you to split out APAC from non-APAC growth. The 100% stacked bar would not.
