Foreign-born residents contributed $1.2 billion to the Portland region’s gross domestic product in 2016, according to a report by the Portland Regional Chamber of Commerce and the Partnership for a New American Economy — a pro-immigration reform coalition of business leaders and mayors founded by former New York Mayor Michael Bloomberg and right-wing media mogul Rupert Murdoch.

The report, which is based on Census figures and other federal data, found that foreign-born residents accounted for 75 percent of the population growth in the Portland region from 2011 to 2016. It estimated that in 2016, immigrant households earned about $679 million, with $133 million of that sum going to federal taxes, $62 million to state and local taxes, $57.3 million to Social Security and $14.7 million to Medicare.

There were 11,063 immigrants living in the Portland region in 2016, making up 10 percent of the population. Nearly 37 percent of them have a bachelor’s degree or higher, compared to the 30-percent average for immigrants nationwide. The top countries of origin for immigrants living in the region were Somalia, Iraq, Vietnam and Cambodia. The report also found that while the foreign-born population made up about 4.6 percent of the Portland metro region, they represented 5.1 percent of the working-age population and 6 percent of its workers in the science, technology, engineering and mathematics (STEM) fields. Roughly 8 percent of the metro-area immigrants were entrepreneurs, while the largest concentrations were in the fields of housekeeping, production work, post-secondary education, nursing and home health aid, and food preparation.

“Because of the role immigrants play in the workforce helping companies keep jobs on U.S. soil,” the report stated, “we estimate that by 2016, immigrants living in the metro area helped create or preserve 1,117 local manufacturing jobs that would have otherwise vanished or moved elsewhere.”
