 The majority of Highland Park's residents are ethnic minorities, with a relatively even split between Latinos, Asians, and African-Americans.The subsection of the neighborhood adjacent to the Oakland Estuary is called Jingletown, also called "JT" by East Oakland natives.The name originated from long ago when there was a Portuguese community in the area and men would gather around on the street corners chatting amongst each other with their hands in their pockets jingling coins.
