Ione - the verdict
Ione ranks in the 60th percentile for household income and the 76th percentile for safety nationally, out of every US city with at least 1,000 residents. Source: Census ACS + FBI UCR.
Population, income, and housing-cost figures come from the U.S. Census Bureau American Community Survey 5-year estimates (B-series tables). Crime data uses FBI UCR; climate uses NOAA Climate Normals; school counts come from NCES Common Core of Data; permits use the Census Building Permits Survey (BPS). See our methodology page for the full ETL pipeline and OMB / FIPS join keys.
California's Ione is a small town, with 5,306 residents per the latest Census Bureau ACS figures. Ione households earn a median of $78,661 annually, above the median for U.S. cities on this measure, with a poverty rate of 2.7%. Typical homes in Ione are valued around $448,300, and the median resident age is 36.9 years. Educational attainment runs 19.3% of adults with a bachelor's degree or higher. Separately, 50.2% of working-age residents are in the labor force.
Housing supply pressure shows in Census Building Permit Survey data: 13 residential units were authorized in 2024 (Construction Slowdown), down 78% from five years earlier. Ione reports a comparatively low crime rate: per-100,000 total crime stands at 705.1 in FBI UCR data, below the national average (a voluntary reporting program, read this as reporting activity, not a definitive danger score).
California carries a cost-of-living premium: BEA Regional Price Parities 2024 puts California at 110.7 on a 100-equals-national-average scale (Well Above Average). A typical two-bedroom carries a HUD Fair Market Rent of $1,698 per month statewide. Monthly utility costs average around $275 across California, per EIA 2023 residential energy estimates. Natural-hazard exposure scores 79.2 out of 100 on FEMA's National Risk Index (High).

Ione measured against every US city with 1,000+ residents, computed live from the same Census and FBI data shown throughout this page.
"Safer than" reflects total crime rate from FBI UCR; the others use Census ACS estimates.
A national percentile can hide a lot of local variation: narrowed to California alone, Ione ranks #27 of 441 California cities by lowest crime rate - a different, more locally useful comparison than stacking it against the entire country.
For each metric we count every US city with population 1,000+ and a non-null value, then compute what share of them fall below Ione's value: round(cities-below ÷ total × 100). Safety is inverted (percentile = share of cities with a higher crime rate) so a higher number always means safer. The in-state rank narrows that same crime-rate comparison to only the cities PlainCities tracks in California, breaking ties alphabetically. See the methodology page for the full source-to-figure lineage.
