Ram and Geeta Chandran had always planned to move into a senior community after they retired. The couple had no children, and “we knew we had to move to a retirement community so we wouldn’t be lonely in a huge house,” said Geeta Chandran, 72, a family physician.

Then they came across an online ad for ShantiNiketan, a planned 55-plus community in Tavares, Fla., designed for Indian-Americans. (The name, in Sanskrit, means “peaceful home.”)

The Chandrans, who had emigrated from India in 1970, found the prospect of aging with others from their home country appealing.

Indian immigrants who came to the United States in the 1960s and ’70s for educational and work opportunities have begun to downsize and contemplate their postcareer years, said Iggy Ignatius, 60, ShantiNiketan’s chairman. “Many people were thinking they’d go back to India, but pragmatically, it’s not possible,” he said. “Our children are here. Our grandchildren are here.”
