It has about 133,000 inhabitants (2010 census [INDEC]). It is the administrative seat of the partido of the same name. It is sometimes called Ciudad de María (City of Mary) due to a series of Marian apparitions that led to the erection of the Sanctuary in honor of Our Lady of the Rosary of San Nicolás that began during the 1980s and were approved by Bishop Cardelli of the diocese as "worthy of belief" in 2016.
