Location
Rioplatense is mainly based in the cities of Buenos Aires, La Plata, Mar del Plata, Santa Fe and Rosario in Argentina, Montevideo in Uruguay, and far south of Rio Grande do Sul in Brazil, the seven most populated cities in the dialectal area, along with their respective suburbs and the areas in between. This regional form of Spanish is also found in other areas, not geographically close but culturally influenced by those population centers (e.g., in parts of Paraguay and in all of Patagonia). Rioplatense is the standard in audiovisual media in Argentina and Uruguay. To the north, and northeast exists the hybrid Riverense Portuñol.
