The number and share of Americans living in multigenerational family households have continued to rise. In 2016, a record 64 million people, or 20% of the U.S. population, lived with multiple generations under one roof.

The increase from these countries exceeded modest growth of the overall foreign-born population and came amid a decline in immigrants from Mexico.

About 629,000 foreign visitors who were expected to leave the U.S. in fiscal 2016 were still in the U.S. when the fiscal year ended Sept. 30.

As the Mexican share of the total declined, the unauthorized immigrant population in the U.S. in 2015 was smaller than when the Great Recession ended.

The increase in the potential labor force will slow markedly as Baby Boomers retire. Immigrants will play the primary role in future growth of the working-age population.

There were 8 million unauthorized immigrants in the U.S. working or looking for work in 2014, making up 5% of the civilian labor force.

About 275,000 babies were born to unauthorized-immigrant parents in 2014, a decline from 330,000 in 2009.

The unauthorized immigrant population in the U.S. – 11.1 million in 2014 – has remained essentially stable since 2009 after nearly two decades of changes.

The estimated total - 11.1 million in 2014 - has steadied since the end of the recession as the number declined from Mexico but grew from other countries.
