San Mateo County has published a mapping application displaying the US Census Bureau block group data by their Hard-to-Count / Least Likely to Respond (HTC/LLTR) index score adapted to our county.  The application also contains the statewide HTC/LLTR index scores for comparison purposes.  The application may be accessed here:  https://maps.smcgov.org/census2020

This map will be useful for identifying demographics for outreach purposes and to better understand where the hardest to count / least likely to respond populations are located in our county.
