Brown County is divided into these nine townships:
Brown County is located in Illinois's 18th Congressional District and is currently represented by Republican Darin LaHood. For the Illinois House of Representatives, the county is located in the 93rd district and is currently represented by Republican Norine Hammond. The county is located in the 47th district of the Illinois Senate, and is currently represented by Republican Jil Tracy.
Brown County is part of the German-settled area of western Central Illinois and the Missouri Rhineland centred on the St. Louis metropolitan area. This region was opposed both to southern plantation owners and socially liberal Yankees and consequently voted against the majority of people in their state. Brown County voted for the Democratic candidate in every presidential election from at least 1840 through 1948, with the sole exception of the 1928 election when the county voted for the Republican candidate Herbert Hoover. From 1952 to 2016, Democrats have carried Brown County only three times (1964, 1976, and 1992) and have won a majority of the vote only once (1964).
