GOIRA estimated there were 550,000 illegal aliens in Texas in 1992. They paid $290 million in state and local taxes and generated state and local service and assistance costs of $456 million, for a deficit of $166 million. Applying the lower estimate of the Immigration and Naturalization Service (INS) of 350,000 illegal aliens in Texas, GOlRA estimated total costs and revenues at $313 million and $183 million respectively, for a deficit of $130 million.
