Number of forced laborers in the German economy 1941-1944, by sector

In May 1941, less than two years after the German invasion of Poland, the total number of forced laborers in the German economy stood at approximately three million people. Around half of these worked in an agricultural capacity, and a third worked in industry. Over the next three years, the number increased to 7.1 million forced laborers, and the industrial sector grew to be the largest user of forced labor.

Forced laborers

Due to the high number of men mobilized, and a reluctance to have women to enter the workforce, the Nazi regime heavily encouraged the voluntary migration of workers from annexed territories in the early years of the war, in order to meet the labor demand of the Reich. There was a small influx of voluntary workers, but it quickly became evident that working conditions were much harsher than expected (especially for Poles), and the stream of workers dried up. In April 1940, authorities in German-annexed Poland then ordered that all available workers born between 1915 and 1925 were required to move to Germany. The largest source of forced labor, however, was from concentration camps; it was mostly Jews and Slavs, as well as other ethnic minorities, political prisoners, criminals, and prisoners of war. Between 1939 and 1944, the number of German laborers also grew substantially; the Nazi regime implemented stricter laws and sentences that punished people for any activities perceived to be critical of or in contrast to Nazi ideology (such as listening to foreign or underground radio stations), and 16 year olds were also sentenced as adults. However, Germans made up a minority of forced laborers in Germany, and this fell to just five to 10 percent of forced laborers by the war's end.

Extermination through work

Most forced laborers were contributing directly to the German war effort, producing food, armaments, and materiel for the front lines. Because of this, their places of work became targets for Allied bombing campaigns, which had a disproportionate effect on Germany's forced labor population. Forced laborers were then used in the active repair and rebuilding of these targeted areas, which exposed them to further raids, undetonated bombs, and chemical hazards. In later years, the share of Gypsies, Jews, and Slavs working in Germany increased further, and the living conditions for these prisoners worsened. As the Reich's resources became stretched, food and provisions for prisoners were rationed, healthcare became non-existent, and work quotas increased; it was only in mid-1944 that the authorities realized how detrimental this was to output and rations were increased. In the winter of 1944-45, as the Soviets pushed west into Germany, many of the larger concentration camps in the east were evacuated and the prisoners were sent on "death marches" to reinforce the workforce in Germany. Some estimates suggest that up to 700,000 prisoners were forced on these death marches (including 56,000 from Auschwitz in mid-January), and between 200,000 and 350,000 were killed. Despite its negative impact on production for the war effort, the extermination of ethnic minorities and so-called "undesirables" by exhaustion was still seen as an overall favorable outcome.
