New Jersey Population 2018


The coastal state of New Jersey is situated on the northeastern edge of the United States and is bordered to the south by the Atlantic Ocean. It has played a prime role in the history of the country, and in terms of the New Jersey population, the state packs a lot of people into a relatively small area. The current estimated population for 2018 is 9.03 million, with a growth rate of 0.41%, which ranks 37th in the country.

The last nationwide census was completed in 2010 and at the time, it was revealed that there were 8,791,894 people living in New Jersey, which equated to a rise of 4.5% on the numbers declared in the 2000 survey.

The most current estimates from July 2015 show a New Jersey population of 8,958,013, which makes it the 11th most populous state in the country, despite being ranked 47th in terms of size.

Statistics relating to density show that New Jersey makes great use of every inch of territory. Its total land mass equates to 8,721 square miles (22,608 square kilometers), making it only the 47th biggest state in the US. The only US states that are smaller than New Jersey are Connecticut, Delaware and Rhode Island.

Despite its lack of size, however, for every square mile of NJ territory, there is an average of 1,195.5 people, which makes it the most densely populated state in the US. New Jersey is the only state to have every single county considered "urban" by the Census Bureau.

Largest Cities in New Jersey

For such a densely populated state, there are only four cities in New Jersey with a population of more than 100,000 people. Newark is the state’s largest city, with a population of 281,944 (based on 2015 estimates), closely followed by Jersey City, home to 264,290 people. The other cities with more than 100,000 people are Paterson (147,754 people) and Elizabeth (129,007).

Most of New Jersey's population lives in the countries surrounding New York City, Philadelphia and the eastern Jersey Shore. The northwestern and very southern counties have a much lower density.

Interestingly, New Jersey is home to more scientists and engineers per square mile than any other area of the world. It's also one of the most religiously and ethnically diverse states in the US, with the second largest Jewish population (after New York state), the second largest Muslim population (after the state of Michigan), the largest population of Peruvians in the country, and the largest population of Cubans outside of the state of Florida. It also boasts very high numbers of Portuguese and Brazilian Americans, Hispanics, Arabs, African-Americans, Asians, Chinese and Italian Americans.

New Jersey was one of the 13 original States, and has had essentially its current boundaries since Colonial times. Census coverage included all parts of the State from 1790 on.

New Jersey Population History

It's a simplistic generalization to say that like most eastern areas of the United States, New Jersey began to fill up quite rapidly in the 1800s. In 1790, 184,139 citizens were living in the state, and that was already a very healthy figure.

Ten years later in 1800, that number had climbed by just under 15% to 211,149 but from the second half of the 19th century onwards, percentage rises in population began to increase on a census by census basis. The growth had gathered so much momentum that by the beginning of the 1900s, the New Jersey population had grown to 1,883,669.

Throughout the 20th century there was less of a pattern in terms of population growth but the overall picture was one of sustained growth to the point where, in the present day, the New Jersey population in 2016 is edging toward the nine million mark. To put that in perspective, that is bigger than more than half of the countries in Europe, and nearly one-third of the size of a country like Canada.

New Jersey Population Projections

New Jersey’s remarkable growth shows no signs of abating and similar increases will take the population comfortably beyond the 9 million mark in 2020. How long this tiny state can sustain those rises without running out of space is a far greater question.

Data gathered show that New Jersey's population will continue to grow and diversify. The population is expected to include more seniors, Hispanics and Asians by 2020, and its projected population growth is fueled by projected gains in employment. The smallest racial groups in the state, Native Americans, Pacific Islanders and Multiracial populations, are projected to increase substantially, increasing 167% between 2010 and 2030. By 2025, it's projected that non-Hispanic whites will no longer claim a majority of New Jersey's population, accounting for just 49.4% of the total population by then.

Current projections estimate New Jersey will have a population of 9.2 million residents by 2020, although it's hard to guess how long the growth can continue.
