The map below shows the County response rates per census tract.  It is important to note that some areas of the county were identified to receive hand-delivered census questionnaires by US Census Bureau staff.  Due to the shelter-in-place restrictions the Bureau has suspended these operations, therefore these census tracts may not have received their questionnaires at this time. 

The census tracts with the ten lowest response rates are identified in the map below, and the  tracts containing an asterik (*) in their labels are those that may not have received their questionnaires yet.   A report containing specific demographic and mapping information about the ten lowest tracts is available here: San Mateo County Census Response Rates: May 28, 2020.
