ZIP 03448 vs ZIP 03445
Source:
Gilsum, NH — Sullivan, NH
This side-by-side compares ZIP 03448 (Gilsum, NH) and ZIP 03445 (Sullivan, NH) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 03448 has a population of 811 at 16 people per square mile, while ZIP 03445 has 691 at 13 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 03448 reports a median household income of $80,417 against $106,667 in ZIP 03445, with per-capita income of $37,262 vs $45,289. The share of adults holding a bachelor's degree or higher is 18.7% in 03448 and 28.5% in 03445. Poverty rate reads 13.4% vs 4.1%, and unemployment 7.4% vs 0.3% — 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 $241,500 in 03448 versus $236,500 in 03445, with median rent of $1,575 and $1,225 per month respectively. Homeownership rate is 93.5% vs 93.6%. 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.
