ZIP 91941 vs ZIP 91977

This side-by-side compares ZIP 91941 (La Mesa, 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 91941 has a population of 31,779 at 1,522 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 91941 reports a median household income of $115,381 against $99,657 in ZIP 91977, with per-capita income of $57,539 vs $39,866. The share of adults holding a bachelor's degree or higher is 47.2% in 91941 and 27.7% in 91977. Poverty rate reads 7.2% vs 9.7%, and unemployment 5.1% vs 8.7% — 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 $928,700 in 91941 versus $665,600 in 91977, with median rent of $2,147 and $1,925 per month respectively. Homeownership rate is 67.5% 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.
