Reading the Rapid City vs Sioux City Comparison

Rapid City (SD) and Sioux City (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 89.2 for Rapid City against 86.5 for Sioux City, a 2.7-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 $1,173/mo in Rapid City and $1,154/mo in Sioux City, a $19/mo difference that compounds to $228 over a year.

Wage data is reported by metro delineation, and one of these metros is missing a BLS record for the latest OES cycle; the salary columns below fall back to available years. State-level violent crime, the most reliable geographic tier FBI UCR publishes, is 320.0 per 100,000 residents in SD vs 238.5 in IA, with property-crime rates of 1535.5 and 1286.3 respectively.

Schools are reported at the state tier by NCES: SD lists 698 public schools at a 13.5:1 student-teacher ratio, while IA lists 1,326 schools at 15.0:1 — a signal of class-size staffing, though individual district and school-level variation within each state is substantial. Department of Labor center-based infant care runs $6,595/yr in the Rapid City area versus $8,306/yr in Sioux City — a line item that shifts the real cost-of-living picture for households with children under five far more than headline RPP does. When these pieces are read together rather than in isolation, Rapid City and Sioux City 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.
