If you've never seen it before, the Census Bureau's On The Map site has great data on commuting patterns. I understand it's based on IRS W-9 data, which records where people live and where they work:

According to this, there are about 40,000 "primary" jobs on the Portland peninsula; about 29% of workers are in the "Health Care and Social Assistance" sector (the hospitals), 14% in "Professional, Scientific, and Technical Services", 10% in hospitality and food service, 7% in Finance and Insurance, and 5% in Retail Trade.
At the same time, only about 12,000 workers live on the peninsula – and of those, about 2/3rds of them commute somewhere off-peninsula for work. About 35K workers commute in to work from outside of the peninsula - almost 90% of downtown workers. Only ~4,400 workers both live and work on the peninsula.
