Journal Publishing Market Distribution per Year
The chart below shows the Lorenz curve for the academic journal publishing market in terms of papers published. The Lorenz curve is typically used in Economics, as "a graphical representation of the cumulative distribution function of the empirical probability distribution of wealth or income" (from Wikipedia.org).
The blue line is the line of equal distribution. The green line shows the line of the actual empirical cumulative distribution function of publisher market shares, from the smallest publishers (left) to the largest (right).
How to read the chart? E.g. from the 2014 chart, one can see that about 94% of smallest Publishers share 10% of the market (or inversely: the 6% largest Publishers share 90% of the market) in terms of papers published in 2014.
