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, fewer families had a stay-at-home parent, and more children were born to single mothers. Society also continued debating issues like affirmative action, standardized testing in education, and how to address challenges from an aging population.
