All you provided is evidence that people moved away from San Francisco during the pandemic. We all know that. Many of the people who left could have afforded to stay and chose not to. That is not displacement.

Proof of displacement requires demonstration that people left SF because they could not afford to live there anymore. It's really that simple.

Techies with six-figure incomes leaving town to move back in with their parents during the pandemic doesn't count as displacement.
