Fifty-six percent of Americans, 178 million, are privately insured. Of these, 156M belong to employer sponsored plans. Only 22M are covered by non-group plans, including those created by the Affordable care Act. The government covers 35% or 112M Americans. Medicaid covers 62M, Medicare 43M and other government plans (e.g., military and Veteran's Administration) covers another 6M. The uninsured number 29 million and make up 9% of Americans. The data from 2015 were compiled by the Kaiser Family Foundation and are presented in the Marimekko chart below:
The data were easy to obtain by downloading a csv file from the KFF website. I pasted the data into a Marimekko chart in PowerPoint, using the Paste Special Transpose command. I then categorized the data into three bars--private, government and uninsured.
I added two rows to my datasheet. In the first, I computed the sum of all my data (e.g., total US population in 2015) and placed it in each column. I used this row as the denominator to calucalue the percentages that appear in each segment by setting this row to the 100% row in the chart. In the second, I computed the % of total data row.
I also sorted the bars and series so that the biggest bars were on the left and biggest series on the bottom of each bar. I scaled the data from KFF to show it in millions on the chart and chose to show the series name, number and percentage in each segment. For series names, I used the full definitions of each series. I then showed these full definitions as my legend. I adjusted my margins to give more space to the legends. I edited the name in each segment to show just the category name (e.g., employer or Medicaid). I also adjusted the segment colors so that each bar had contained different shades of the same base color.
