German cities Düsseldorf, Munich, Nuremberg and Frankfurt share eighth place in a survey of the world's safest cities published on Monday. The report, by Mercer Human Resource Consulting, evaluated 215 locations for crime levels and internal stability, using New York as the base city with a score of 100 points. The German cities all recorded a score of 113 points. The world's safest city is Luxembourg while, unsurprisingly, Baghdad is the most dangerous. While the German cities fared well, Rome, Athens and London performed badly compared to other western European locations because of high levels of petty crime, while Madrid scored poorly because of terrorism, the report showed. "The top-ranking cities for personal safety and security are in politically stable countries with good international relations and sustainable economic growth," said Slagin Parakatil, Senior Researcher at Mercer on the company's Web site.
