Riverdale, New Jersey, is a small borough, measuring only 2.1 miles square, with a 2010 population of 3,559, nearly 50% more than the population in 2000. As a small borough in Morris County, the eighth-wealthiest county in the United States, Riverdale is a notably rich borough; the median family income is roughly $80,000. Like other boroughs in the state, Riverdale is governed by a council and a mayor. This borough is surrounded by the boroughs of Butler, Bloomingdale, Kinnelon, Pompton Lakes and the township of Pequannock, which Riverdale broke free from in 1923.

This small town values independence; the homepage of the borough reflects the view that merging towns is a bad idea, and it looks with disfavor on recent plans that take state money out of the local school districts. Because of the high median income and proximity to New York, Riverdale is clearly a very nice place to live. Many of the scenic New Jersey state parks are only a short drive away, and New York City is close enough for an exciting weekend getaway.
