The One Million Jews Mistake?

Most Jews? U.S or Israel?

Two new independent studies have found that there are between 6.4 million and 6.6 million Jews living in the United States today, representing about 1.8% of the population. One study out of Brandeis by Leonard Saxe, the 6.4 million figure and another study out of the University of Miami and University of Conneticut by Ira Sheskin and Arnold Dashevsky are creating a debate which is the newest tempest in a teapot. With all the pronouncements about the newly found million Jews, we don’t know anything more about one single Jew in the US than we did before this “PEGGING” of US Jews at the over 6.4 million mark rather than the previous 5.2 million which would have made Israel at 5.8 million Jews the largest Jewish population in the world.

It all hinges on how hundreds of thousands of US respondents answered the generic religion survey question on dozens of general surveys in the US and whether Jewish screening questions were properly applied in more specialized Jewish population studies.  In both cases, as an experienced demographer, I would worry before I made a rash announcement of an million extra Jews in the U.S.  There are other serious issues as to estimation assumptions, such as using 3 to 10 year old surveys which provide no household members information to estimate current Jewish population figures based on current population estimates.

Its a reach to use the methodologies that Saxe, in the Brandeis study, and the Sheskin and Dashevsky study use to estimate U.S. National Jewish populations.  If my experience with false positives, that is non-Jews claiming to be Jewish, in local Jewish surveys in Los Angeles, San Francisco, Seattle and Houston is ramped up to a national scale and ignored then I would expect a number much higher than it actually is.

As described in a recent Forward article:

Daunted by the steep expense and lengthy time required by random digit dialing, Saxe and his team ferreted out data that already existed to reach his conclusion. This included information from more than 150 government surveys on topics completely unrelated to Judaism, such as health care or education. Each study had a sample size of at least 1,000 people, and each study asked the question: What is your religion?

So, as long as US Jews don’t actually do a needed $10-14 million scientific survey, we retain bragging rights over Israel on the basis of guesstimates.

Now that we’ve cheaply built this Jewish demographic castle in the air…when do we move in?
