In comparison, the largest industry in most states accounts for less than 6.0% of total GDP.

Several West Coast states are known for their substantial tech sectors. Washington state is home to giants Microsoft and Amazon, while California, of course, has Silicon Valley.

Computer and electronic products manufacturing employs more than 37,000 people and generates over $34 billion annually.

Lately however, the sector has been a drag on the state’s economy. Oregon’s computer and electronics manufacturing subsector contracted by a staggering 34.2% in the last five years.
