North Arlington is a borough in Bergen County, New Jersey, United States. As of the 2010 United States Census, the borough's population was 15,392, reflecting an increase of 211 (+1.4%) from the 15,181 counted in the 2000 Census, which had in turn increased by 1,391 (+10.1%) from the 13,790 counted in the 1990 Census.
As the site of Holy Cross Cemetery, which has interred almost 290,000 individuals since its establishment in 1915, and with another Jewish cemetery including several thousand more burials, North Arlington has more than 20 times as many dead people than living, with more burials than the living population of Newark, the state's largest city. Holy Cross has an average of 2,600 interments each year, of which about 65% are burials, with the remainder split between entombment in mausoleums or crypts and burial of cremated remains. Expansion of the mausoleum will bring its capacity to nearly 36,000 interments, with the cemetery's total capacity of about 750,000 expected to last past the year 2090. The cemetery covers 208 acres (84 ha) and was assessed at $185 million, though its non-profit status means that the municipality generates no tax revenue from a property that covers almost an eighth of the borough's land area.
North Arlington was formed by a referendum passed on March 9, 1896, and incorporated as a borough by an act of the New Jersey Legislature on March 11, 1896, from area taken from Union Township. It was called North Arlington because it was north of the Arlington section of Kearny, which had been named from the Arlington Station on the Erie Railroad.
