Lemon Grove, CA — Spring Valley, CA

This side-by-side compares ZIP 91945 (Lemon Grove, CA) and ZIP 91977 (Spring Valley, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 91945 has a population of 25,460 at 2,505 people per square mile, while ZIP 91977 has 58,368 at 2,333 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 91945 reports a median household income of $88,016 against $99,657 in ZIP 91977, with per-capita income of $36,715 vs $39,866.

Poverty rate reads 9.2% vs 9.7%, and unemployment 5.4% vs 8.7% — these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

Homeownership rate is 52.5% vs 63.8%. 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.
