Demographics & GIS


The U.S. Census Bureau collects a host of data on the nation's people and economy. This involves numerous surveys regularly conducted by the Bureau, the most well-known being the census taken every ten years of population and household demographic characteristics. In 2005, the Census Bureau initiated the American Community Survey, a continuous detailed survey of economic, social, demographic, and housing characteristics intended to complement the decennial census. Census data is reported at a wide range of geography, from the nation as a whole down to states, counties and smaller areas.

Below are links to sources of Census data that the NJTPA regularly draws upon in assessing the traveling needs of the residents of northern New Jersey (indicates links to outside websites):

Regional Facts

Some key facts for the NJTPA region are as follows:

  • NJTPA’s Census 2010 population is 6,579,907, 75 percent of NJ’s total population.

  • Between 2000 and 2010, the region grew by nearly 270,000 people, or 4.3 percent over the 10-year period, which equates to an average annual growth rate of 0.4 percent. NJTPA’s 4.3 percent growth over the decade was just slightly under the statewide average growth of 4.5 percent (and substantially lower than the national average of 9.7 percent).

  • Ocean County saw the most growth from 2000 to 2010—66,000 people—and had the highest percentage of growth in the NJTPA region at 12.8 percent.

  • The only county in the NJTPA region that lost population from 2000 to 2010 was Essex County, dropping by about 10,000 people or 1.2 percent of its population 10 years earlier. Irvington saw the greatest population drop, down 6,800 people or 11 percent, followed by East Orange, which lost 5,500 residents or 8 percent. However, those losses were slightly offset by a gain of 3,500 people, or 1.3 percent, in Newark.

  • In Hudson County, Jersey City—the second largest city in the state behind Newark—grew by 7,500 people, or 3. 1 percent.
