ZIP 30004 vs ZIP 30009

This side-by-side compares ZIP 30004 (Alpharetta, GA) and ZIP 30009 (Alpharetta, GA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 30004 has a population of 53,033 at 357 people per square mile, while ZIP 30009 has 13,722 at 552 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 30004 reports a median household income of $156,100 against $126,510 in ZIP 30009, with per-capita income of $76,606 vs $77,189. The share of adults holding a bachelor's degree or higher is 72.2% in 30004 and 66.8% in 30009. Poverty rate reads 5.0% vs 7.8%, and unemployment 3.1% vs 3.3% — 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 $657,700 in 30004 versus $640,500 in 30009, with median rent of $2,029 and $2,055 per month respectively. Homeownership rate is 74.1% vs 61.6%. 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.
