“Study finds self-esteem levels vary by age, race”
An interesting new study published in the Journal of Personality and Social Psychology also found no significant differences in self-esteem levels between men and women during teenage and young adult years.

Although Hispanics tend to have lower self-esteem than blacks or whites in the teen years, by age 30 their self-esteem has increased to the point that they have higher self-esteem than whites, a new study suggests. And in both adolescence and young adulthood, blacks have higher self-esteem than whites.
