According to a chart published by the World Health Organization in 2015, the average life expectancy for a woman in the United States is 81 years. A man's average life expectancy is 76 years. These statistics reflect data from the year 2013.
While genetics play a factor in the predisposition to certain diseases that may shorten a woman's lifespan, environmental factors also play a large role in life expectancy. Workplace hazards, smoking and alcoholism are examples of variables that may contribute to a shorter lifespan, while attention to nutrition and a person's overall health may contribute to an extended life expectancy.
