The Oklahoma House of Representatives is the lower house an larger body of the two houses of the Oklahoma Legislature, the other being the Oklahoma Senate. Originally, each county in Oklahoma was represented in the House proportional to its population, but after a court case in the early 1960s, the state has been divided into 101 House districts of equal population. Representatives serve two-year terms and each House member represents approximately 35,000 constituents. The presiding officer of the House is known as the Speaker of the Oklahoma House of Representatives.
