The Microregion of Ijuí (Brazilian Portuguese: Microrregião de Ijuí) was one of the Microregions of the Rio Grande do Sul state, in Brazil. It belonged to the mesoregion of the Noroeste Rio-Grandense.[1] Its population was estimated by the IBGE to be of 183.142 inhabitants in 2005, and it was divided in 15 Municipalities. Its total area was of 5.100,402 km². The IBGE has since discontinued the microregion system for population tracking, replacing it with the term "immediate geographic region" (Brazilian Portuguese: Região geográfica imediata).[2]
