As of the 2010 United States Census, the township's population was 28,370, reflecting an increase of 1,008 from the 27,362 counted in the 2000 Census, which had in turn increased by 263 from the 27,099 counted in the 1990 Census.What is now Nutley was originally incorporated as Franklin Township by an act of the New Jersey Legislature on February 18, 1874, from portions of Belleville Township. Nutley was incorporated as a Town on March 5, 1902, replacing Franklin Township. In 1981, the town was one of seven Essex County municipalities to pass a referendum to become a township, joining four municipalities that had already made the change, of what would ultimately be more than a dozen Essex County municipalities to reclassify themselves as townships in order take advantage of federal revenue sharing policies that allocated townships a greater share of government aid to municipalities on a per capita basis.
