The Paris department was actually called Seine until 1968, named after the river. Côte-d'Or, which literally translates as "golden slope", is the only department not named after some form of geography. Var, in the south, is named after the Var river, even though the Var river doesn't run through Var. In fact, the department was named in 1790 after the Cher river. Yvelines in the south west of Paris is the least hit by poverty, with just 8.2 percent below the poverty line.
