Joshua Comenetz has broken down the American Jewish population by Congressional district.
Here are the local numbers:
| District | Representative | Jews | % |
|---|---|---|---|
| PA1 | Robert Brady (D) | 17,000 | 2,41% |
| PA2 | Chaka Fattah (D) | 36,000 | 5,10% |
| PA6 | Jim Gerlach (R) | 19,000 | 2,69% |
| PA7 | Pat Meehan | 36,000 | 5,10% |
| PA8 | Mike Fitzpatrick (R) | 44,000 | 6,24% |
| PA13 | Allyson Schwartz (D) | 63,000 | 8,93% |
| NJ1 | Robert Andrews (D) | 35,000 | 4,78% |

The estimate of the Jewish population in all Congressional Districts is 6,735,830, approximately 2.18% of the total U.S. population. This estimate is consistent with the 6.7 million Jewish persons reported in the 2013 Pew Research Center Portrait of Jewish Americans….
The American Jewish population is simultaneously more densely clustered geographically than the overall American population and very geographically diverse — at least a few Jews live in every one of the 436 CDs. Half of all American Jews live in just 37 CDs, and 93 CDs contain three-quarters of all Jews. In contrast, the 266 districts with the fewest Jews collectively have only 10% of the Jewish population. The most-Jewish district, New York’s 10th, has as many Jews (197,000) as the 170 least-Jewish CDs combined.
There are 13 CDs with 100,000 or more Jews, nine in New York and two each in California and Florida — the three states with the highest total Jewish populations. In general, the most-Jewish CDs are in the northeastern states, California, Florida, and a few other large urban areas such as Chicago and Atlanta. The least-Jewish CDs are mostly in the rural parts of southern states.
Pennsylvania’s 13th Congressional District has the most Jews in the state and is ranked 24th nationally while the 3rd, 5th and 9th District have only 1000 Jews.
Where is the Jewish vote the most decisive?
There are 27 Congressional Districts in which the Jewish population exceeded the margin of victory in the 2012 Congressional election. Heading the list is:
Illinois’ 10th Congressional District whose 76,500 Jews (10.73% of the population) is about 23 times the 3,326 vote margin by which Democratic challenger Brad Schneider defeated Republican incumbent Robert Dold.
Florida’s 32th Congressional District whose 32,000 Jews (4.60% of the population) is about 17 times the 1,904 vote margin by which Democratic challenger Patrick Murphy defeated Republican incumbent Allen West.
New York’s 11th Congressional District whose 129,000 Jews (17.97% of the population) is about 12 times the 10,688 vote margin by which Republican incumbent Michael Grimm defeated Democratic challenger Mark Murphy.
