Solano County is very diverse, with nearly two-thirds of the population identifying as BIPOC (Black, Indigenous, and People of Color).
Population by Age Groups
Below is a breakdown of the Solano County population by age group. There are fewer residents within the age categories on either end of the scale; the vast majority of residents fall between the ages of 5-74. However, the county is seeing a general shift toward the older population. As of 2023, approximately 18% of the population is age 65 or older, but this is expected to grow to about 26% by 2070.
Population by Age and Sex
Below is an age pyramid further broken down by sex. Each age group has relatively equal subpopulations of males and females, although there are generally more females than males from age 60 and up. In Solano County, persons of female sex can expect to live about 5 years longer than persons of male sex (82.63 years versus 77.46 years, respectively [source: Institute for Health Metrics and Evaluation, 2019 estimates]).
Note: The source file for this graphic has built-in, 5-year age groups so the groups are smaller than those shown in the above bar graph.
