URJ meaning in Community ?

The Union for Reform Judaism (URJ), known as the Union of American Hebrew Congregations (UAHC) until 2003, founded in 1873 by Rabbi Isaac Mayer Wise, is the congregational arm of Reform Judaism in North America. The other two arms established by Rabbi Wise are the Hebrew Union College-Jewish Institute of Religion and the Central Conference of American Rabbis. The current president of the URJ is Rabbi Rick Jacobs.

The URJ has an estimated constituency of some 880,000 registered adults in 873 congregations. It claims to represent 2.2 million, as over a third of adult U.S. Jews, including many who are not synagogue members, state affinity with Reform, making it the largest Jewish denomination. The UAHC was a founding member of the World Union for Progressive Judaism, of which the URJ is the largest constituent by far.
