ZIP 29555 vs ZIP 29546

This side-by-side compares ZIP 29555 (Johnsonville, SC) and ZIP 29546 (Gresham, SC) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 29555 has a population of 6,440 at 27 people per square mile, while ZIP 29546 has 2,834 at 8 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 29555 reports a median household income of $43,011 against $32,043 in ZIP 29546, with per-capita income of $23,530 vs $21,878. The share of adults holding a bachelor's degree or higher is 13.2% in 29555 and 10.4% in 29546. Poverty rate reads 37.6% vs 38.8%, and unemployment 12.9% vs 7.7% — 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 $151,000 in 29555 versus $97,100 in 29546, with median rent of $633 and $671 per month respectively. Homeownership rate is 71.0% vs 69.5%. 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.
