Rich people will live up to 15 years longer than poor ones.
A rich 40-year-old man in the United States can expect to live until about 87. A poor 40-year-old man might only live until 73.
The difference in length of life as it relates to income is part of a new study published in the Journal of the American Medical Association.
The Health Inequality Project studied about 1.4 billion income tax records from a 15-year period ending in 2014. While people might have guessed that wealth allows for a longer life, the study reviewed more data than any similar studies in the past.
The researchers say it is not only bad to be poor. They say it is worse to be poor in certain parts of the United States than others. Poor people in depressed cities like Detroit, Michigan; Toledo, Ohio; and Gary, Indiana are worse off than poor people in places like San Francisco, California and New York City.
