The object of this study is a community of 80,000 retired people living in ‘The Villages’, a child-free ‘active adult retirement community’ in central Florida (USA). All property owners and most of the residents, bar a smattering of under-age partners and household members, are over 55 years of age. Others may visit, for limited periods, as monitored guests. Children and adolescents are not welcome. “Those under the age of 19 can visit for a MAXIMUM of 30 days a year but may not live with you permanently in your home.”
