What’s behind Mount Sinai’s civic life grade
Mount Sinai isn’t graded on civic life: TownRatings grades towns of 1,000 residents or more.
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.
Library visits: IMLS Public Libraries Survey, FY2024. Nonprofits: IRS Exempt Organizations Business Master File, October 2026. Volunteering: Social Capital Atlas (Opportunity Insights), from data by Meta Platforms, Inc.; Chetty et al., Nature 2022. How TownRatings grades civic life →

Civic life: — = not graded (unincorporated places, whose nonprofits can’t be placed by mailing address, or towns with fewer than two of the three inputs).
What this data can and can’t tell you
From the Public Libraries Survey, fiscal year 2024.
- The library’s own count. Libraries report their own visits, loans and programs. A library that didn’t respond keeps its address and hours here, with no numbers.
Hours are the survey’s yearly average; libraries are compared with others serving about as many people. How TownRatings uses library figures →
