How to read this matchup
Reading the St. Louis vs Waterloo Comparison
St. Louis (MO) and Waterloo (IA) are assembled here from the same federal data pipeline, BEA Regional Price Parities, HUD Fair Market Rents, BLS Occupational Employment and Wage Statistics, FBI Uniform Crime Reports, NCES public-school counts, and EPA environmental indicators, so every number on this page is directly comparable. The overall cost index reads 95.1 for St. Louis against 87.1 for Waterloo, a 8.0-point gap on a scale where 100 equals the U.S. average. HUD's 2-bedroom Fair Market Rent, the figure used to set housing-choice voucher payment standards, is $916/mo in St. Louis and $1,051/mo in Waterloo, a $135/mo difference that compounds to $1,620 over a year.
On wages, BLS OES reports a median salary of $68,074 across 1,311,920 jobs in St. Louis against $61,344 across 77,420 jobs in Waterloo. Adjusted through the BEA cost-of-living lens, $100,000 earned in St. Louis carries the same local purchasing power as $91,554 in Waterloo - the most honest way to read the salary headline, because nominal wages and rents move together in tight metros. State-level violent crime, the most reliable geographic tier FBI UCR publishes, is 463.3 per 100,000 residents in MO vs 238.5 in IA, with property-crime rates of 1971.6 and 1286.3 respectively.
Schools are reported at the state tier by NCES: MO lists 2,321 public schools at a 12.8:1 student-teacher ratio, while IA lists 1,326 schools at 14.8:1, a signal of class-size staffing, though individual district and school-level variation within each state is substantial. When these pieces are read together rather than in isolation, St. Louis and Waterloo are not simply "cheaper" or "more expensive" - they trade across dimensions, and which metro wins depends on whether your household optimizes for rent, wages, schools, childcare, safety, or environment. Treat the tables below as inputs to that trade-off, not as a single ranking.
