The passage of Republic Act No. 9371 on February 22, 2007 increased the city's representation by reapportioning it into two congressional districts:[2]barangays west of the Cagayan de Oro River were constituted into the first district, and those lying east of the river, the second. The districts elected their separate representatives starting in that year's elections.
