As of the 2020 census, the population was 606,612, making it the 10th most populated county in Florida. The official county seat has been located in Titusville since 1894. Brevard County comprises the Palm Bay–Melbourne–Titusville, FL Metropolitan Statistical Area. It is located along the east Florida coast and bordered by the Atlantic Ocean.
With an economy strongly influenced by the John F. Kennedy Space Center, Brevard County is also known as the Space Coast. As such, it was designated with the telephone area code 321, as in “3, 2, 1 liftoff”. The county is named after Theodore Washington Brevard, an early Florida settler and state comptroller.
A secondary center of county administrative offices was built beginning in 1989 in Viera, Florida, a master-planned community in an unincorporated area. The county offices were developed to serve the more populous southern part of the long county. Wikipedia
