I am looking at table B19013 for Median Household Income in a particular CBG (Block Group 4, Census Tract 42, Tulare County, California) and the 2021 5 year estimate is missing. It was present in the 2019 5 year estimate table, however. The guide to data…

Try the C23002 race series (with letters A-I at the end). Some data for smaller populations could be suppressed. Here's the link for C23002B (Black -- each zip had data) - I don't use the A race letter for White as prefer non-Hispanic White under letter…
