Based on the results of the 2000-01 survey, the total Jewish population in the United States was estimated at 5.2 million, comprising 4.1 million adults and 1 million children. An additional 100,000 Jews in institutional settings were not sampled as part of NJPS but are included in the total. This total represents a decline from the 1990 NJPS, which estimated a total Jewish population of 5.5 million people. Jews who have married since 1996 have an intermarriage rate of 47%.[1]

There were no survey performed in 2010 due to the lack of funding. The 2000-01 NJPS – which by some estimates cost nearly $6 million, far more than budgeted – was widely criticized, both for its findings and for its methodology. United Jewish Communities, the survey’s sponsor, announced afterward that it would not sponsor future national population surveys.[2]

The demographer Gary Tobin fiercely criticized the Survey, saying that the it severely undercounted American Jews due to methodological flaws[3] and calling it "utter nonsense".[4] He estimated that over a million more Jews were present in the United States than the 2000 Survey suggested.[3] Tobin NJPS undercounting occurred due to Jews who do not declare themselves Jewish out of concern for antisemitism, due to under-weighing of West Coast Jews, and as a result of an overly-strict definition of Jews excluding self-described cultural or ethnic Jews.[4]
