It is bicameral, comprising the Oklahoma House of Representatives and the Oklahoma Senate, with all members elected directly by the people. The House of Representatives has 101 members, each serving a two-year term. The Senate has 48 members, each serving a four-year term. Members of both houses are elected from single member districts of equal population. Senators serve a staggered term, such that only half of the senate districts have elections in any election year.
