A larger share of part-timers among women may mean that female eamings are distributed more unequally than men’s. At the same time, there is little empirical evidence on changes in female earnings inequality over time. Since changes in annual eamings depend on both eamings and hours worked, this section discusses differences and similarities in trends for both of these factors for men and women. On average, the Gini coefficient (where 0 represents perfect equality and 1 perfect inequality) was two percentage points higher among women in the late 2000s. Germany showed the largest gender difference, with women’s Gini being almost 8 points higher than men’s, followed by Mexico and Spain. On the other hand, in Belgium, the Czech Republic and the United States there was no sizeable difference in eamings inequality between men and women.
