A year into the pandemic, Silicon Valley has experienced historic losses and unprecedented gains as the virus has disproportionately impacted the area's poorest residents. Unemployment among the region's lowest earners reached nearly double the rate of the highest earners. And while the in-person jobs sector shrank, the tech industry experienced a banner year. Families facing housing insecurity reached an all-time high, while a hot real estate market outpaced pre-pandemic numbers.

To show how the pandemic has accelerated the region's economic divide, the Palo Alto Weekly, The Almanac and Mountain View Voice have woven together data based on Joint Venture Silicon Valley's State of the Valley report into a by-the-numbers graphic.
