About Jefferson

Jefferson is a census-designated place (CDP) in Jefferson Parish, Louisiana, United States, on the north side (referred to as the "East Bank") of the Mississippi River. Jefferson is part of the New Orleans–Metairie–Kenner metropolitan statistical area. The population was 11,193 at the 2010 census, and 10,533 in 2020. It is often known by locals as "Old Jefferson" (to distinguish itself from the rest of Jefferson Parish), but should not be confused with Old Jefferson in East Baton Rouge Parish, Louisiana. == History == Early French colonial documents show what would become Jefferson as part of the "Tchoupitoulas Coast" of Native American settlement.
