New piece by Zeit (@colorfuldata et al) on street names in Germany allows to search for custom terms. I compared streets referring major cities (e.g. "Berliner Straße", "Frankfurter Allee"). Ordered from north to south.
Some visible tidbits: Berlin obviously wins. Frankfurt has two centers (with Frankfurt am Main and Frankfurt/Oder). Munich is split in two maps at the right bottom: demonym "Münchner" more often in the South, and "Münchener" in the rest.
