Source:

Thompson, CT — North Grosvenordale, CT

This side-by-side compares ZIP 06277 (Thompson, CT) and ZIP 06255 (North Grosvenordale, CT) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 06277 has a population of 4,140 at 70 people per square mile, while ZIP 06255 has 4,744 at 81 per square mile. That difference in population size and density alone reshapes how every other metric should be interpreted — a higher-income ZIP with 1,200 residents behaves very differently from one with 45,000.

On income and education, ZIP 06277 reports a median household income of $110,000 against $88,750 in ZIP 06255, with per-capita income of $59,703 vs $49,513. The share of adults holding a bachelor's degree or higher is 22.9% in 06277 and 25.8% in 06255. Poverty rate reads 4.1% vs 8.3%, and unemployment 7.6% vs 2.9% — these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

Housing separates these two ZIPs further: median home value sits at $295,100 in 06277 versus $312,200 in 06255, with median rent of $1,490 and $926 per month respectively. Homeownership rate is 89.0% vs 78.3%. When reading the comparison table below, focus on paired metrics rather than single winners — a ZIP with lower home values and lower income is not strictly "worse" if rent-to-income ratios and commute times land in the same zone. Every value is pulled from the exact same ACS table so the two columns are genuinely comparable.
