At the end, the Stasi had 97,000 employees—more than enough to oversee a country of seventeen million people. But it also had over 173,000 informers among the population. In Hitler’s Third Reich it is estimated that there was one Gestapo agent for every 2000 citizens, and in Stalin’s USSR there was one KGB agent for every 5830 people. In the GDR, there was one Stasi officer or informant for every sixty-three people. If part-time informers are included, some estimates have the ratio as high as one informer for every 6.5 citizens.
