ZIP 29420 vs ZIP 29456
Source:
North Charleston, SC — Ladson, SC
This side-by-side compares ZIP 29420 (North Charleston, SC) and ZIP 29456 (Ladson, SC) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 29420 has a population of 21,834 at 751 people per square mile, while ZIP 29456 has 27,864 at 590 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 29420 reports a median household income of $72,661 against $78,361 in ZIP 29456, with per-capita income of $39,165 vs $37,076. The share of adults holding a bachelor's degree or higher is 32.4% in 29420 and 24.0% in 29456. Poverty rate reads 12.0% vs 9.0%, and unemployment 4.4% vs 4.5% — 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 $331,700 in 29420 versus $270,100 in 29456, with median rent of $1,529 and $1,650 per month respectively. Homeownership rate is 62.2% vs 61.7%. 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.
