American society was changing at the beginning of the 21st century due to increased immigration and changing demographics. The Immigration Act of 1990 increased immigration quotas and eased restrictions, bringing over 1 million new immigrants to the US annually, who were mostly Latino and Asian. This increased immigration led to debates over bilingual education and illegal immigration. At the same time, families were also changing as divorce became more common, and more babies were born to single mothers. Affirmative action and legislation protecting women also remained topics of debate as American society adapted to rapid change at the turn of the century.
