Madison County is a county located in the U.S. state of Idaho. As of the 2010 census, the population was 37,536.[1] The county seat and largest city is Rexburg.[2]

Madison County is part of the Rexburg, ID Micropolitan Statistical Area, which is also included in the Idaho Falls-Rexburg-Blackfoot, ID Combined Statistical Area.

History[edit]

The area was originally settled by members of The Church of Jesus Christ of Latter-day Saints (Mormons). Before February 1913, the county was part of neighboring Fremont County. The newly established county was named for American president James Madison.[3] BYU-Idaho, formerly Ricks College (named after early local LDS settler Thomas Edwin Ricks) is located here. Madison County was declared a national disaster area after the Teton Dam flood of June 5, 1976.

Government and politics[edit]

Similar to other Idaho counties, an elected three-member county commission heads the county government. Other elected officials include clerk, treasurer, sheriff, assessor, coroner, and prosecutor.[4]

With a strongly conservative and Mormon population, Madison County is one of the most staunchly Republican counties in the United States. Since 1980 no Republican presidential candidate has failed to carry the county with less than 59 percent of the vote. In that same period Republican presidential candidates polled more than 90 percent of the county's vote on three occasions, Ronald Reagan in 1984,[5] George W. Bush in 2004,[6] and Mitt Romney in 2012.[7] John McCain came close to this level in 2008, drawing 85 percent of the vote.[8]

At the state level Madison County is located in Legislative District 34,[9] which currently has an all-Republican delegation in the Idaho Legislature.[10]

Geography[edit]

According to the U.S. Census Bureau, the county has a total area of 473 square miles (1,230 km2), of which 469 square miles (1,210 km2) is land and 4.0 square miles (10 km2) (0.8%) is water.[11] It is the third-smallest county in Idaho by area.
