That map is inaccurate. Unfortunately slavery is still very much a thing in many parts of the world, including forced labour, prostitution and some sweat shop labour.
The PRC and North Korea still use slave labour as do some other countries. The Soviet Union had slavery with the Gulag system during the 20th century, and other places such as East Germany had some within living memory.
