ZIP 19720 vs ZIP 19706
Source:
New Castle, DE – Delaware City, DE
This side-by-side compares ZIP 19720 (New Castle, DE) and ZIP 19706 (Delaware City, DE) using the same Census ACS 5-Year table fields for both, no averages swapped in, no national proxies. ZIP 19720 has a population of 59,250 at 617 people per square mile, while ZIP 19706 has 1,822 at 191 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 19720 reports a median household income of $75,403 against $83,681 in ZIP 19706, with per-capita income of $36,945 vs $38,807. The share of adults holding a bachelor's degree or higher is 23.3% in 19720 and 23.6% in 19706. Poverty rate reads 10.9% vs 6.1%, and unemployment 3.6% vs 7.2% - 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 $265,000 in 19720 versus $263,000 in 19706, with median rent of $1,363 and $1,511 per month respectively. Homeownership rate is 67.6% vs 74.5%. 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.
