The study found that in Bucks County, Pennsylvania — one of the areas closely watched this election cycle — Jewish adults make up more than 6 percent of the population.
BOSTON — A new study, touted as the first-ever state-by-state, county-by-county Jewish population estimate, shows how the Jewish vote could play a crucial role in key battleground states.
The study, released Thursday and conducted by the Steinhardt Social Research Institute at Brandeis University in suburban Boston, found that in Bucks County, Pennsylvania — one of the areas closely watched this election cycle — Jewish adults make up more than 6 percent of the population.
“That’s three times more than the national numbers” of Jews, said research associate Daniel Parmer.
Jewish voters have a record of higher-than-average turnout.
“If it’s a tight race,” Parmer said, “Jewish voters could swing the election” in that county.
The study also shows how the Jewish vote could have significant impact in Florida’s Palm Beach area, where the 209,400 Jews there make up nearly 15 percent of the adult population, according to the study.
That number is significant in a state where President Barack Obama won by less than 1 percent in 2012, or 74,309 votes.
The study also looked at American Jews’ party identification, finding that 54 percent of American Jews identify as Democrats, while 14 percent identify as Republicans.
But only 43 percent of American Jews call themselves liberal, a lower percentage than those who say they are Democrats.
“We see a higher proportion of Jews who identify as Democrats but a lower proportion have liberal political views,” Parmer said. “Conversely, there are more Jews who identify as conservative [21 percent] than Jewish Republicans.”
The results also show that 36 percent of American Jews consider themselves neither liberals nor conservatives, and that 32 percent identify as neither Democrats nor Republicans.
The American Jewish Population Project’s latest report, which is based on population figures from 2015, includes new data on gender and race, as well as population profiles for major metropolitan areas on the East Coast, West Coast and Chicago.
The study and updated map is based on nearly 250 independent samples of the U.S. adult population collected from 2008 to 2015. This includes more than 280,000 respondents, of whom nearly 6,000 are Jewish.
The institute’s director, Leonard Saxe, along with Parmer and the population project’s director, Elizabeth Tighe, sat down in advance of the release of the data to talk about the numbers.
Among the most notable findings is the diversity among Jewish millennials — young adults aged 18 to 34. The study puts the number of millennials who identify as Jews “by religion” at 1.4 million.
The study shows a decline in party identification among millennials, with 37 percent saying they identify with neither Democrats nor Republicans. Among those who do identify, 51 percent of millennials say they are Democrats, compared to 56 percent of Jewish adults aged 65 or older who identified as such. Only 12 percent of millennials say they are Republicans.
The study also finds perhaps surprising diversity among the younger Jews, with 30 percent identifying as non-white. That’s more than double the figure for Generation X, those born from the early 1960s to mid-1970s.
The information is relevant at the local level, where most Jewish community surveys do not include the racial breakdown, said Parmer, who noted the diversity in two New York City boroughs: Nearly 12 percent of Manhattan’s Jews identify as non-white, while in the Bronx, the figure swells to nearly 30 percent. He said this has implications for the political issues they care about, like social justice and racial inequality.
Overall, the study estimates that 4.2 million adults identify as Jewish “by religion.” Adding Jewish adults who identify in some other way plus an estimate for the number of Jewish children results in an overall population estimate of 7.16 million.
Saxe noted the challenges of estimating the Jewish population: the small sample size, the absence of religion data in the U.S. Census and disagreement about criteria for determining who is a Jew.
The population of Jews who identify by religion is consistent with the 2013 Pew Research Center’s “Portrait of Jewish Americans,” whose results were factored into the study.
“The population is continuing to grow,” Saxe said. If you read media reports, “you might think the sky is falling and that we are continuing to see declines in the Jewish population, and that’s not the case.”
Other highlights of the study include:
- 57 percent of Jewish adults are college graduates.
- More than 1 in 10 Jewish adults identify as a person of color.
- More than one-quarter of Jewish adults are 65 years of age or older.
- Nearly 50 percent of the U.S. adult Jewish population lives in one of three states: New York (23 percent), California (13 percent) or Florida (13 percent).
The researchers say that the study’s state-by-state analysis could be useful in understanding the Jewish dynamics of November’s presidential election.
