Analysis
What drives eviction risk in Somerville
The severe-burden share is 30%, and it is the single best predictor in this model of a filing that actually reaches judgment. Set annual rent against average income of $36,135 and the ratio lands at 39%, above the conventional 30% ceiling. The main counterweight is supply constraint at 1.5/10.
The poverty rate is 30%. Judgments in high-poverty tracts are collectible far less often than filing counts suggest. Running hot, court filing pressure reads 8.2/10. On the high side, regional political climate reads 8.2/10.
Against the Philadelphia County average of 6.6, this tract reads riskier for landlords by 1.4 points. Average gross rent is $1,171, 16% below the Philadelphia average. The filing record is not thin: 376 evictions over 4 years of observation.
Filings peaked in 2012 at 29.9% of renter households. This ground was mapped C ("Definitely Declining") on the 1930s HOLC security maps for Philadelphia. That grading determined who could get a mortgage, and its imprint on tenure and rent burden is still visible in the ACS data above. In a typical year about 21.5% of renter households face a filing.
These are ACS 5-year estimates; the score moves when the ACS, court-record, or statute inputs behind it move.
