In of the wage income distribution inequality

In the left side panel, the development of the wage income distribution inequality for men and women in West Germany, is illustrated. It can be seen that the starting point at the beginning of the 90s was for both, men, with a value of  2, as well as for women, value of 1.9, very similar. A value of 2 means that people from the upper percentile earned about double the gross wage of the people from the lower percentile. Until the mid-1990s, this relation remains relatively stable. But then, from 1996 to 2011, there is a strong growth in the inequality of income distribution. Even though both values have always been very close to each other, it is still recognizable that from 2005 to 2011, the distribution of wages within men has split more than that of women. In other words, inequality among men’s wages increased more.(ibid.)
Both values reached their peak in 2011. The men almost reached a value of 2.7, which represents a 35% increase in inequality of wage distribution, and among women the indicator rose by about 40%. However, the turnaround in 2011 is striking, no further growth can be reported after that. From 2011 to 2014, the value of men stagnated and even slightly declined for women.(ibid.)
In the right chart, the development for eastern Germany is shown. First of all, we can discover some similarities to West Germany. Shortly after the reunification, the values of men and women are around 1.9. The course of the growth of inequality and the turnaround in 2011 are also very similar.
However, a few key differences are striking. The growth of inequality for wage distribution already started at the beginning of the 90s. Furthermore, since 1992, the value of women in East Germany exceeds that of men. This becomes even clearer as the development progresses. The inequality indicator for women is obviously above that of men. In other words, the spread of women’s wage distribution is significantly bigger then for men in East Germany.
These values also reached their peak in 2011 with an inequality indicator of 2.9 for women and 2.6 for men. This means an increase in the disparity of wage distribution by 50% among women and 40% among men, within 20 years.(ibid.)
