What’s behind Castle Rock’s civic life grade
On community nonprofits and volunteering, Castle Rock is ahead of 39% of U.S. towns, #65 of 104 in Colorado. Castle Rock is graded on two of the three inputs. Both inputs sit below most U.S. towns; the share of younger adults in volunteering groups comes closest to the middle.
Most U.S. towns with similar household incomes ($109K–$181K) score higher, so income alone doesn’t account for it.
Civic life counts registered nonprofits, library visits and online volunteering groups, so it can miss civic life that runs through congregations, mutual aid or neighbors looking out for each other.
