Edwards County was named for Ninian Edwards,^[3] the governor of the Illinois Territory, and, later, governor of Illinois.

Edwards County is subdivided into "Road Districts", rather than "Townships" as in most Illinois counties. Pursuant to the Land Ordinance of 1785, the Northwest Territory (including Illinois) was surveyed and mostly organized into townships that are six miles square; but Edwards County was settled prior to that survey, and its pre-existing Road Districts do not generally correspond with the survey's townships.

• Edwards County, when it was created in 1815 from Gallatin and Madison Counties, extended north to Lake Michigan.
• The county between 1816 and 1819. Clark and White Counties were created from Edwards and Gallatin Counties.
• The county between 1819 and 1821. At this point Crawford County was split off from Edwards, and Wayne Counties.
• Edwards between 1821 and 1824
• Edwards in 1824, reduced to its current size by the creation of Wabash County

According to the U.S. Census Bureau, the county has a total area of 223 square miles (580 km²), of which 222 square miles (570 km²) is land and 0.3 square miles (0.78 km²) (0.1%) is water.^[4] It is the fourth-smallest county in Illinois by area.

When Edwards County was formed in 1814, it comprised nearly half of the State of Illinois. New counties were formed from it until, in 1824, it assumed its present form from the creation of Wabash County. The two are the fourth and fifth smallest counties in Illinois.

Edwards County is separated from Wabash County by the Bonpas Creek.

As of the 2010 United States Census, there were 6,721 people, 2,840 households, and 1,926 families residing in the county.^[12] The population density was 30.2 inhabitants per square mile (11.7/km²). There were 3,187 housing units at an average density of 14.3 per square mile (5.5/km²).^[4] The racial makeup of the county was 98.0% white, 0.4% black or African American, 0.3% Asian, 0.1% American Indian, 0.3% from other races, and 0.8% from two or more races. Those of Hispanic or Latino origin made up 0.9% of the population.^[12] In terms of ancestry, 26.8% were German, 22.4% were English, 13.3% were American, and 8.4% were Irish.^[13]

Of the 2,840 households, 28.9% had children under the age of 18 living with them, 54.8% were married couples living together, 8.3% had a female householder with no husband present, 32.2% were non-families, and 28.5% of all households were made up of individuals.

Edwards County is one of the most consistently Republican counties in the nation. It has voted for the Republican candidate in all Presidential elections from 1856 to present, except in 1912 when the party was divided and Theodore Roosevelt won the county as the “Bull Moose” Progressive candidate.^[15] In the last five Presidential elections no Democratic candidate has reached 34 percent of the county's vote.^[16] Edwards County also holds the distinction of having the lowest percentage of any Illinois county of votes for governor Pat Quinn, a Democrat, in his failed 2014 reelection bid. Quinn lost 101 of the 102 counties in Illinois, capturing only 13.7% of the vote in Edwards County.^[17] Hillary Clinton fared even worse in 2016 with only 13.1 percent of the county's ballots. The last Democrat to win the county was Andrew Jackson in 1832.

In other positions the county has been not been consistently Republican for as long, but nevertheless has been so for many years. The last Democratic Senatorial candidate it backed was Alan J. Dixon in 1986^[19] and the last Democratic gubernatorial candidate it supported was Glenn Poshard, who carried all of Southern Illinois in his failed 1998 bid.^[20] Edwards County lies in Illinois's 15th congressional district, which has Cook Partisan Voting Index of R+21 and has been represented by Republican Mary Miller since 2021.

Edwards County is a dry county, with multiple referendums to allow alcohol sales failing in the mid-1990s. The portion of Grayville, Illinois that lies within Edwards County does allow alcohol sales per Grayville city ordinance.^[21]
