Data Methodology & Sources
CityClick operates under a strict Zero-Hallucination policy. Every metric rendered on our platform is tied to an official federal, state, or municipal database with verified vintage.
📊 Demographics, Income & Labor Force
Total resident population, 5-year growth trajectory, median household income (MHI), per capita income, and daytime commuter labor inflow ratios are compiled directly from official Census ACS tables.
💼 25-Trade NAICS Saturation Index
To prevent statistical distortion in smaller communities while accurately measuring saturation in major metros, establishment density per 10,000 residents is smoothed using Empirical Bayes shrinkage against national trade priors across 25 primary NAICS retail and service categories.
Commercial lease rates ($/sqft/year) reflect asking triple-net (NNN) commercial retail benchmarks reconciled against regional brokerage reports and county appraisal district commercial records.
🏔️ Terrain Elevation & Climate Normals
Precise municipal elevation above sea level is resolved using exact municipal centroid coordinates queried against the National Elevation Dataset (NED).
🚰 Municipal Drinking Water & Public Safety
Every municipal profile references the primary active Public Water System ID (e.g. `TX2270001` for Austin Water, `AR0000208` for Hot Springs Village), primary source classification (groundwater aquifer vs surface water reservoir), and Safe Drinking Water Act compliance status.
Public Audit & Corrections Policy
If you are a municipal official, civil engineer, or local business owner and notice a changed permit fee, new utility district, or adjusted school boundary, submit verification evidence to our research desk at [email protected]. Verified corrections update within 48 hours.
