LOWEST RATE OF INCOME INEQUALITY AMONG COUNTIES COMPARED

Income inequality, or the gap between the rich and the poor, has been increasing in the United States since the 1980s and is higher than most industrialized countries. High income inequality is associated with poorer public health, reduced socioeconomic mobility, and reduced feelings of well-being among those at the low end of the income distribution.[1] This indicator measures the level of income inequality among households in San Bernardino County using the Gini Index.  

Gini Index Scale

Gini Index results range between zero (0) and one (1). A value of zero indicates complete equality, where all households have equal income. A value of one indicates complete inequality, where only one household has any income.

TREND

San Bernardino County’s Gini Index has remained mostly stable, decreasing less than 1% since 2019, from 0.434 in 2019 to 0.435 in 2024. 

GEOGRAPHIC COMPARISON

The San Bernardino County 2024 Gini Index score of 0.435 is lower than the California score (0.485) and the national average (0.483).  Among the 42 California counties with populations of 65,000 or more, San Bernardino County has less income inequality than all but four (Kings, San Benito, San Joaquin, and Placer).  In comparison to selected peer and neighboring counties, San Bernardino County has the least income inequality.
