New Jersey has an adult population of 7.28 million people, with more than one-in-four (27%) identifying as secular or non-religious, according to the Pew Research Center. This means that nearly 2 million residents in the Garden State have no religious affiliation.

A slight majority (52%) of secular adults in New Jersey are women, while 46% are men. One in five of secular New Jersey residents is under the age of 30, while less than 20% are over 65. Three-quarters of New Jersey secular adults are white, while 25% belong to various communities of color.

During the 2024 presidential election, New Jersey saw approximately 4.27 million voters casting their ballots. According to data from the AP/NORC VoteCast, about 22% (nearly one million) of the state’s voters identified as secular. 

Democratic Party candidate Kamala Harris won New Jersey’s Electoral College votes against Donald Trump. A major factor in her success was the support of secular voters. A striking 72% of secular voters sided with Harris, while only 26% voted for Trump. This overwhelming support included more than seven in ten men, women, adults both under and over 40, as well as both white secular individuals and secular people of color.

Despite accounting for one in five voters in the state, secular voters cast three out of every ten votes supporting Harris, but just over one out of ten of Trump’s.
