How much population did germany lost in the treaty of versailles?

In the 1919 Alliance of Versailles, the victorious governments (the United States, Great Britain, France, and other allied states) inflicted disciplinary territorial, soldiery, and financial stipulations on destroyed Germany. In the west, Germany restored Alsace-Lorraine to France. It had been taken by Germany more than 40 years beforehand. Moreover, Belgium got Eupen and Malmedy; the manufacturing Saar territory was distributed under the supervision of the League of Nations for 15 years, and Denmark took Northern Schleswig. Eventually, the Rhineland was removed all military forces from; that is, no German armed troops or support were authorized there. In the east, Poland seized portions of West Prussia and Silesia from Germany. In extension, Czechoslovakia took the Hultschin region from Germany; the mostly German city of Danzig converted an independent city below the camouflage of the League of Nations; and Memel, a short piece of area in East Prussia near the Baltic Sea, was eventually settled under Lithuanian administration. Outside Europe, Germany missed all its dependencies. In total, Germany relinquished 13 percent of its European region (larger than 27,000 square miles) and one-tenth of its residents (connecting 6.5 and 7 million men and women).
