Villages are privately funded organizations that are often supported with member dues and funding from nonprofits. They provide services to seniors, usually with volunteers, that help them stay in their homes as they age. There are an estimated 55 village programs throughout the country and more than 100 in the planning stage. Services include home maintenance and repairs, transportation for shopping errands and appointments, social events, and discounted prices for local products and services. Here, Dori Li leads a Tai Chi class organized in Boston by Beacon Hill Village, one of the first and most extensive village programs.
