Traditional retirement planning has long assumed a household of at least two people and often the involvement of adult children in managing financial decisions later in life.
But more and more, that assumption no longer applies to a growing share of retirees. Surveys and data show that many people living in the U.S. are charting a different course, with roughly 1 in 5 over the age of 50 living alone. (That number rises to 27% for those age 60 and older.) And about 23% never had children.
