how old is senior citizen
People in the United States who are more than sixty years of age are commonly referred to as senior citizens or seniors. These terms refer to people whose stage in life is generally called old age, though there is no precise way to identify the final stage of a normal life span. People are said to be senior citizens when they reach the age of sixty or sixty-five because those are the ages at which most people retire from the workforce. U.S. law and society recognize the special needs of senior citizens. The most important aid to senior citizens is the Social Security program. More than twenty-five million Americans receive old-age benefits each month under federal Old-Age, Survivors, and Disability Insurance, and those payments amount to almost $20 billion a year.
