Dover is a majority minority community, with nearly 70% of the population as of the 2010 census identifying themselves as Hispanic, up from 25% in 1980.Semuels, Alana.

"Segregation isn't just happening between black and white towns. Hispanic and Asian residents are segregated into their own cities and towns, too. Dover, New Jersey, for instance, a town 30 miles west of New York, was 70 percent Hispanic in the 2010 Census. In 1980, it was only 25 percent Hispanic."

History Joseph Latham was deeded the land that includes present-day Dover in 1713, from portions of land that had been purchased from Native Americans by the Proprietors of West Jersey. On May 31, 1722, Latham and his wife Jane deeded over to John Jackson of Flushing, New York. Jackson settled on the eastern portion of his land along Granny's Brook at the site of what would later become the Ross Ribbon Factory on Park Heights Avenue.Daigle, Michael. "Dover at the Millenium" , Daily Record, February 25, 1999. Accessed April 27, 2012.

Iron ore at the time was so plentiful that it could be collected off the ground at the nearby Dickerson Mine in Mine Hill. At Jackson's Forge, ore would be processed into bars that would then be transported to Paterson and other industrial areas towards the east. The passage of the Iron Act by the British Parliament led to financial difficulties, leading Jackson into bankruptcy in 1753, with all of his property and belongings sold off at a Sheriff's sale. Quaker Hartshorne Fitz Randolph purchased Jackson's property and annexed to his own existing property, which would later become part of Randolph Township.Kullen, Charlotte G. "Randolph — A Day in the Life" , Daily Record, October 21, 1999. Accessed April 27, 2012. "It is here that in 1722, Dover's first European settler, John Jackson, built an iron forge that gave birth to the industry that for the next 21 centuries would shape the growth of the town... The ban wiped out Jackson, who sold his farm to Hartshorne Fitz Randolph, for whom the modern township is named, and his forge to Josiah Beaman."

Dover was incorporated as a town on April 1, 1869, within Randolph Township and became fully independent as of March 5, 1896.Honeyman, Abraham Van Doren.

On May 7, 1896, Dover was reincorporated as a city and regained its status as a town on March 21, 1899, after the referendum that approved the change was invalidated by a court ruling.Snyder, John P.

In its past, Dover has had extensive iron and mill works, machine shops, stove, furnace, and range works, boiler and bridge works, rolling mills, drill works, knitting and silk mills, and a large hosiery factory (MacGregors). During this period, Dover was a port on the Morris Canal while it was operational; the boat basin was located at what is today the JFK Commons Park.Daigle, Michael.
