Peer Group
A set of cities grouped by population size for comparison purposes, ensuring that small cities are compared to other small cities, not mega-cities.
How It Works
CitySpend uses three peer groups based on Census Annual Population Estimates: large (250,000+ population, approximately 100 U.S. cities), midsize (100,000-250,000 population, approximately 200 cities), and small (50,000-100,000 population, approximately 500 cities). The 50,000 population floor aligns with the Census Annual Survey of State and Local Government Finances universe for detailed city-level reporting and with HUD's CDBG entitlement threshold. Peer group comparisons are essential because city spending and revenue patterns vary systematically with size. Large cities have economies of scale in administrative functions (per-capita general administration spending typically declines from roughly $250 per capita in small cities to $150 in large cities), but they face higher costs in others such as labor (unionization rates in large cities exceed 50% for public workers per BLS data, versus 20-30% in small cities), land acquisition for facilities and right-of-way, and complexity premiums for multi-jurisdictional coordination. Large cities more often operate stand-alone school districts, hospitals, transit systems, and airports that increase their total per-capita spending without reflecting operational inefficiency. Comparing a 60,000-person suburban city to New York City would produce misleading conclusions on nearly every metric. The Lincoln Institute's Fiscally Standardized Cities (FiSC) database applies similar peer-grouping logic to its 150-city dataset, aggregating city, school district, county, and special district spending to achieve apples-to-apples comparisons. CitySpend additionally subgroups by region (Northeast, Midwest, South, West) and by state within peer groups where sample size permits, because state laws on home rule, debt limits, pension governance, and revenue authority significantly influence municipal finance. Peer group medians and distributions inform every factor of the Fiscal Health Score, particularly the 20% debt burden, 15% spending efficiency, and 10% revenue diversity factors.
