With a few exceptions in low-income countries, people worldwide are living longer, having fewer children (or not having them at all), and having children later in life. Generally, there has been a shift away from intergenerational living towards older individuals and households living without younger generations. These trends mean there is an increased burden on a smaller number of family members to provide informal caretaking for older family members. The main takeaway for planners is there is a growing need for housing and service options for aging adults, along with access to transit and community support (especially for more rural areas).
