The Utah State Senate is a body of 29 men and women elected to four-year terms. About half of the senate seats are up for election every two years on an alternating basis. Each senator represents a constituency of approximately 77,000 population. A senatorial district may be a county, a portion of one country or two or more counties, or a combination of both. Redistricting of the senate takes place as required by law to insure that each senator represents as nearly as possible approximately the same number of constituents.
