Hunedoara started to grow very fast after the communist regime started to industrialize the country. The steel works of Hunedoara became and important industrial factor in the country's economy and attracted numerous migrants from all over the country. Located in the west of Rumenia, the city has always had a substantial percentage of German, Hungarian and Roma inhabitants.
After the fall of the communist regime the industry fell into disrepair and nowadays only a small portion of the factories is still operating. The population has shrunk accordingly from 89.000 to 57.00 inhabitants (https://en.wikipedia.org/wiki/Hunedoara)
