This policy brief describes two types of walking among California adults: walking for transportation and walking for leisure. Using data from the 2013-14 California Health Interview Survey, the study found that the prevalence of both types of walking has increased since 2003. The prevalence of walking for both transportation and leisure varies with age, income, race/ethnicity, and neighborhood safety and cohesion. Additional efforts by state and local policymakers, as well as by communities, are needed to reduce disparities and promote walking among adults.
