One of the first decisions that had to be made in conducting this study and analyzing its results was to answer the question, \u201cWho is a Jew?\u201d This is an ancient question with no single, timeless answer. On the one hand, being Jewish is a matter of religion \u2013 the traditional, matrilineal definition of Jewish identity is founded on halakha (Jewish religious law). On the other hand, being Jewish also may be a matter of ancestry, ethnicity and cultural background. Jews (and non-Jews) may disagree on where to draw the line. Is an adult who has Jewish parents but who considers herself an atheist nevertheless Jewish, by virtue of her lineage? What about someone who has Jewish parents and has converted to Christianity? Or someone who has no known Jewish ancestry but is married to a Jew and has come to think of himself as Jewish, though he has not formally converted to Judaism?<\/p>\n\n
Various readers will have their own answers to these questions. The approach taken in this survey was to cast the net widely, seeking to interview all adults who answer an initial set of questions (the \u201cscreener\u201d) by saying (a) that their religion is Jewish, or (b) that aside from religion they consider themselves to be Jewish or partially Jewish, or (c) that they were raised Jewish or had at least one Jewish parent, even if they do not consider themselves Jewish today. Anyone who said \u201cyes\u201d to any of these questions was eligible for the main interview, which included many more questions detailing religious beliefs and practices; denominational affiliations such as Reform, Conservative and Orthodox; synagogue and Jewish community connections; the religious affiliation of parents, spouses, partners and children in the home; attitudes toward Jewish identity; social and political views; and demographic measures such as age and education. This wide-net approach gives readers (and scholars who later conduct secondary analysis of the survey data) a great deal of flexibility to apply whatever definitions of \u201cJewish\u201d they think are appropriate.<\/p>\n\n
This report analyzes the survey data using four main categories. These are defined to be as consistent as possible with previous major surveys of U.S. Jews (e.g., by counting as Jewish not just religious Jews but also people of Jewish upbringing, even if they are not religious) while still making intuitive sense to a general U.S. audience (e.g., by not counting as Jewish anyone who describes him\/herself as a Christian or who does not consider him\/herself Jewish). The categories are:<\/p>\n\n
\n
Jews by religion \u2013 people who say their religion is Jewish (and who do not profess any other religion);<\/li>\n
Jews of no religion \u2013 people who describe themselves (religiously) as atheist, agnostic or nothing in particular, but who have a Jewish parent or were raised Jewish and who still consider themselves Jewish in some way.<\/li>\n<\/ul>\n\n
These first two groups constitute, for the purposes of this analysis, the \u201cnet\u201d Jewish population. In addition, the survey interviewed:<\/p>\n\n
\n
Non-Jewish people of Jewish background \u2013 people who have a Jewish parent or were raised Jewish but who, today, either have another religion (most are Christian) or say they do not consider themselves Jewish;<\/li>\n
Non-Jewish people with a Jewish affinity \u2013 people who identify with another religion (in most cases, Christianity) or with no religion and who neither have a Jewish parent nor were raised Jewish but who nevertheless consider themselves Jewish in some way. Some say, for example, that they consider themselves partly Jewish because Jesus was Jewish, because \u201cwe all come from Abraham\u201d or because they have Jewish friends or relatives.<\/li>\n<\/ul>\n\n
Most of this report focuses on the net Jewish population (Jews by religion and Jews of no religion). Whenever the views or characteristics of U.S. Jews (or just \u201cJews\u201d) are discussed, this refers to the combined categories of Jews by religion and Jews of no religion. The characteristics and attitudes of people of Jewish background and people with a Jewish affinity are discussed separately in Chapter 7<\/a> of this report.<\/p>\n\n
