The Hispanic population in Houston is increasing as more immigrants from Latin American countries come to work in the area. As of 2006 the city has the third-largest Hispanic population in the United States. As of 2011, the city is 44% Hispanic. As of 2011, of the city's U.S. citizens that are Hispanic, half are age 18 or older, and are therefore at the age range eligible to vote. As of 2011 many Hispanics in Houston are not U.S. citizens, especially those living in Gulfton and Spring Branch, and are therefore ineligible to vote in elections. As a result, Hispanics have proportionally less representation in the municipal government than other ethnic groups. As of April 2011 two of the Houston City Council members are Hispanic, making up 18% of the council.
