Oregon runs on immigrant labor.

That's one of the inescapable conclusions of a report released Aug. 3 by a coalition of state government and business leaders demanding Congress enact comprehensive immigration reform.

The group, led by Oregon House Speaker Tina Kotek (D-Portland) and the Oregon Association of Nurseries, wants Congress to make it easier for immigrants to enter Oregon. It's an uneasy alliance: progressive politicians and preachers are teaming with the business lobby, which wants more laborers. They face an uphill battle. Even before the groundswell of anti-immigrant feeling that buoyed Donald J. Trump, Oregon voters soundly rejected a 2014 measure to let undocumented workers get driver's licenses.

But the coalition calling itself Reason for Reform isn't appealing to the higher virtues of Oregonians. It's aiming its case at the wallet. The group's report argues that immigrants in Oregon create new jobs and pour $2.4 billion a year into state and federal tax coffers.

The 42-page report is jammed with figures from 2014 on legal immigrants and undocumented workers. Here are four questions it addresses.

1. How many Oregonians were born abroad?

That's 388,960 people.
