The bar chart illustrates what proportion of the gross domestic product was dedicated to healthcare in a number of European countries. The data covers the years 2002, 2007 and 2012, and is given as percentages.
Immediately we note that there is not much change over time in the figures for each country. Switzerland spent the highest percentage of their GDP over the entire time period (a constant 11%), whereas Estonia allocated the lowest proportion (an invariable 3%). However, this does not imply anything about the amount of money expended by these states, as their gross domestic product might differ. The numbers for the other 10 countries fall somewhere in between the two aforementioned extrema, with an estimated average of about 7%.
Notice how the highest proportions are encountered in the Western nations, by contrast with the less developed Estonia (3%), Lithuania (5-6%) and Poland (6-7%). Also relevant is how for most countries (5) the percentage of the GDP expended over time increases by 1% between 2007 and 2012. Even still, for quite a large number of countries (4) the numbers remain constant.
Thus, we conclude that the healthcare expenditures for the 12 given European countries do not change very much over time, usually increasing if they do so. The difference in proportions across states is also of note, with the less developed nations allocating smaller percentages of their GDP.
