The 32nd annual Demographic Workshop, held virtually this year, is built around the theme, “The Post-Pandemic City.'' Participants are taking a close look at several intersecting developments that could significantly change life in the six-county SCAG region, including the pandemic and post-pandemic recovery, heightened awareness of racial equity and inclusion, and results of the 2020 Census. The latter already will result in California losing a Congressional seat.
