CDC data show insomnia varies by family income level and gender

The percentage of U.S. men and women who report that they regularly have insomnia or trouble sleeping decreases as family income increases, according to data from the 2012 National Health Interview Survey. The Morbidity and Mortality Weekly Report from the Centers for Disease Control and Prevention also notes that at every family income level, women are more likely than men to have insomnia or trouble sleeping.
