Societal For the purposes of this assessment, adaptive capacity is the ability of a demographic group to cope or compensate for the loss of function.

The Adaptive Capacity (AC) scores were rated on a 5-point scale from Very Low to Very High.

Indicators

Statewide Comparison Among all the indicators, the watershed's share of renter-occupied housing s the only one that is more than one standard deviation from the state average.

That is, the watershed on average has a higher share of renters than the state overall.

Adaptive Capacity Variables: 1. Elderly Living Alone 2. With Disability 3. Limited English Proficiency 4. Single Parent Households 5. Hispanic or Non-White 6. Median Household Income 7. Renter-Occupied Housing Units 8. Rent-Burdened Households 9. Without a Bachelor’s Degree 10. Unemployment 11. No-Vehicle Households 12. Transit Accessibility

Vulnerability Ranking

Renter-Occupied Housing Units Sources 1. US Census 2010 2. ACS 2014-18 5-Year Estimates 3. ArcGIS Network Analyst

Key Findings

Mapping Risk Malden, Medford, Somerville, Woburn, Cambridge, and Everett have the highest number of census tracts with low adaptive capacity and flood risk.
