Garfield is a city in Bergen County, New Jersey, United States. As of the 2010 United States Census, the city's population was 30,487, reflecting an increase of 701 from the 29,786 counted in the 2000 Census, which had in turn increased by 3,059 from the 26,727 counted in the 1990 Census.When the area that is now Garfield was first developed in 1873, it was known as East Passaic. In 1881, the community's name was changed to Garfield in honor of President of the United States James Garfield. There are two explanations given for the circumstances behind the renaming. According to one, shortly after Garfield was elected to the presidency the founder of East Passaic said, "tell everyone...don't speak of East Passaic anymore; call it 'Garfield' after the man who will lead this great country to prosperity." Seven months later, President Garfield was assassinated but his name remained with the community.
