In January 2007, 20 of the 27 Member States of the EU had national legislation setting statutory minimum wages. They varied widely, from €92 per month in Bulgaria to €1 570 per month in Luxembourg. When adjusted to take into account differences in purchasing power, the disparities between the Member States are reduced from a range of one to seventeen (in euro), to a range of one to seven (in PPS2) with Luxembourg (1 503 PPS per month) the highest and Romania (204 PPS) the lowest.
