ZIP 30106 vs ZIP 30122

This side-by-side compares ZIP 30106 (Austell, GA) and ZIP 30122 (Lithia Springs, GA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 30106 has a population of 20,300 at 632 people per square mile, while ZIP 30122 has 21,561 at 346 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 30106 reports a median household income of $68,881 against $69,257 in ZIP 30122, with per-capita income of $34,556 vs $36,293. The share of adults holding a bachelor's degree or higher is 29.1% in 30106 and 33.7% in 30122. Poverty rate reads 13.3% vs 11.6%, and unemployment 4.9% vs 3.9% — 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 $288,100 in 30106 versus $262,500 in 30122, with median rent of $1,455 and $1,608 per month respectively. Homeownership rate is 55.9% vs 47.8%. 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.
