HOYERSWERDA, GERMANY - JULY 07:  A former street sign stands among paved streets where apartment buildings once stood in Wohnkomplex X (WK X, or Living Complex X) district on July 16, 2015 in Hoyerswerda, Germany. City authorities demolished much of WK X in 2013 due to an endemic housing glut. Hoyerswerda was largely built by the communist East German authorities in the 1950s in order to house workers needed for nearby coal mines, power plants and factories, and by 1981 had a population of over 70,000. After the collapse of the communist government in 1989 the factories shut down and coal production declined, resulting in a population that has sunk to around 34,000 today, making Hoyerswerda the city with the starkest population decline in Germany. 25 years since German reunification eastern Germany is struggling with a low birth rate, rural emigration and unemployment rates higher than in western Germany.
