This article compares the degree of Yiddish language maintenance in the United States with other European languages brought to America by immigrants. The languages selected for this purpose are German, Polish, Greek and Italian. Apart from the German-speaking group, all arrived in the U.S.A. at approximately the same time, the end of the 19th century and the first part of the 20th. The German-speaking immigration reached its peak somewhat earlier, but large numbers continued to arrive during the 20th century. With the use of Census data we will attempt to trace the degree to which the
mother tongue has been transmitted from one generation to another.
