ZIP 03444 vs ZIP 03450

Source:

Dublin, NH — Harrisville, NH

This side-by-side compares ZIP 03444 (Dublin, NH) and ZIP 03450 (Harrisville, NH) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 03444 has a population of 1,590 at 22 people per square mile, while ZIP 03450 has 961 at 20 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 03444 reports a median household income of $104,773 against $103,036 in ZIP 03450, with per-capita income of $48,766 vs $67,042. The share of adults holding a bachelor's degree or higher is 45.6% in 03444 and 54.8% in 03450. Poverty rate reads 9.9% vs 3.6%, and unemployment 1.7% vs 3.0% — 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 $429,600 in 03444 versus $430,500 in 03450, with median rent of $1,325 and $1,611 per month respectively. Homeownership rate is 83.4% vs 94.3%. 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.
