The inhabitants of Reggio nell'Emilia are called Reggiani, while the inhabitants of Reggio di Calabria, in the southwest of the country, are called Reggini.

The old town has a hexagonal form, which derives from the ancient walls, and the main buildings are from the 16th–17th centuries. The commune's territory lies entirely on a plain, crossed by the Crostolo stream.
