Coronel Suárez has a population of 23,621 inhabitants (2010) and its main economic activities are related to agriculture and cattle raising.

The latter partido, and its main town, were named after Manuel Isidoro Suárez (1799–1846), a colonel in the Argentine Army who fought in the wars of independence against the Spanish and led the Peruvian and Colombian infantry to victory in the Battle of Junín in the Junín Region of Peru on August 6, 1824.

Colonel Suárez was the great grandfather of the writer Jorge Luis Borges.

The city was founded on 28 May 1883 by Eduardo Casey on the frontier of Indian territory and a fort was built beside the river Sauce Corto.

There are parades, dinner, shows, exhibitions of crafts, traditional products and sports competitions.
