Page "Interfaith marriage" Paragraph 9

In the early 19th century intermarriage was comparatively rare – less than a tenth of a percent ( 0. 1 %) of the Jews of Algeria, for example, practiced exogamy, but since the early 20th century, rates of Jewish intermarriage have increased drastically.

In the United States of America between 1996 and 2001, nearly half ( 47 %) of marriages involving Jews were intermarriages with non-Jewish partners, and a similar proportion ( 44 %) existed during the early 20th century in New South Wales.
