Derby, CT

The affordability dashboard for Derby, CT aggregates Census ACS 5-Year Estimates across 1 ZIP code covering 12,914 residents, then layers in county-level federal data to produce an overall grade of C- (53/100). The headline inputs are median household income of $78,542, median home value of $258,500, median rent of $1,452 per month, and 35.5% of adults holding a bachelor's degree or higher. These four metrics alone explain most of the variance between city dashboards.

Cross-agency feeds widen the picture beyond Census demographics. HUD publishes a Fair Market Rent for a 2-bedroom in this county at $1,895 per month (studio $1,299, 1BR $1,569, 3BR $2,283, 4BR $3,182). Department of Labor data lists infant center-based childcare at $18,200 per year, consuming 23% of the local median household income.

Reading the overall grade requires reading all seven dimensions together. The score weights Income 20%, Safety 20%, Housing 15%, Rent 15%, Education 10%, Commute 10%, and Childcare 10%, with each sub-score benchmarked against national percentiles rather than state averages — so the grade is genuinely comparable across any city in the country. Pressure points are childcare. Unemployment currently reads 5.7% and poverty 11.0% — numbers worth keeping alongside the headline grade.
