Description:
This data set represents all urbanized tracts within the San Francisco Bay Region, and contains attributes for the eight Metropolitan Transportation Commission (MTC) Communities of Concern (CoC) tract-level variables for exploratory purposes.
MTC 2018 Communities of Concern (tract geography) is based on eight ACS 2012-2016 tract-level variables:
- Minority (70% threshold)
- Low-Income (less than 200% of Fed. poverty level, 30% threshold)
- Level of English Proficiency (12% threshold)
- Elderly (10% threshold)
- Zero-Vehicle Households (10% threshold)
- Single Parent Households (20% threshold)
- Disabled (12% threshold)
- Rent-Burdened Households (15% threshold)
If a tract exceeds both threshold values for Low-Income and Minority shares OR exceeds the threshold value for Low-Income AND also exceeds the threshold values for three or more variables, it is a CoC.
Detailed documentation on the production of this feature set can be found in the
MTC Communities of Concern project documentation.
