There was a nationwide recession in the United States in the early '90s. The chart reflects that.

And FYI, technology was not a significant factor in the economy of the City of San Francisco at that time.

So was the 80's tech boom in Silicon Valley limited to the valley proper?

For most of Silicon Valley's history, the technology industry was generally no farther north than Menlo Park on the Peninsula, and southern Fremont in the east, with the occasional exception (Electronic Arts in San Mateo, Oracle in Redwood Shores). There were the beginnings of a tech presence in SOMA in the dot-com era, but it died when the bubble burst. Tech didn't start to come back to the City until 2006-07 or so.
