Jefferson County is one of only a handful of counties in the Florida Panhandle that usually favors the Democratic Party. In 2016 it flipped and Donald Trump won the county.
The Jefferson County School District is the only one in Florida operating under a declared financial emergency due to budget deficits.  On April 23, 2009, the Florida Department of Education took over financial oversight of the district.  In June 2011, the District exited financial emergency one (1) year sooner than expected due to hard work and sacrifice of the part of District faculty and staff. The District has now operated for two years with a fund balance well over the mandated 3%. The District is proud to be financially sound. Academically, the District is showing huge gains in reading and writing. In 2013 there is a new sense of excitement on the part of students, faculty and the community as all are working hard to provide a high quality education delivered with fidelity in a safe, secure environment. Career Academies have been introduced on the campus of Jefferson County Middle High School offering students options in career areas connected to the local economy. The Jefferson County Tigers won the State Championship in Football in 2011.
Jefferson County's library is the R.J. Bailar Public Library, which works with the Wilderness Coast Public Libraries.

- Interstate 10 is the main west-to-east interstate highway in the county, and serves as the unofficial dividing line between northern and southern Jefferson County. It contains three interchanges within the county; the first being SR 59 in Lloyd (Exit 217), the second at US 19 in Drifton (Exit 225), and the third south of Aucilla at CR 257 (Exit 233). Beyond this point I-10 runs through Madison County.
- US 19 is the westernmost north-south US highway in the county. It enters from southwestern Madison County as the Georgia-Florida Parkway in a concurrency with US 27, then breaks away from US 27 in Capps to run straight north through Monticello where it encounters a traffic circle with US 90 around the historic Monticello Courthouse. North of the city it runs through the State of Georgia.
- US 27 is another north-south US highway in the county. It enters from Madison County in a concurrency with US 19, but unlike US 19 breaks away at Capps and runs west toward Tallahassee
- SR 59 is the westernmost north-south highway in Jefferson County and is the only roadway connection between U.S. 90 (at its intersection in Leon County) to the southernmost east-west route through Jefferson County, U.S. Route 98.
- US 90 was the main west-to-east highway in the county, until it was surpassed by I-10. It enters the county from Leon County twice, the second time from a causeway over the southern end of Lake Miccosukee, and eventually enters Monticello in a traffic circle with US 19. East of the city, it curves southeast through rural Jefferson County, then passes north of Aucilla before crossing the Madison County Line at a bridge over the Aucilla River.
- US 98 is the southernmost east-west route running through the Conservation Areas of the Gulf of Mexico from Wakulla to Taylor Counties. The sole major intersection is with SR 59.
- US 221 is the easternmost US highway in the county, running south and north through the northeastern portion of Jefferson County, including Ashville before crossing the Georgia State Line.
