Race and well-being

A well-being score was calculated for MIDUS respondents based on the following items: has a cheerful happy disposition; feels good about self; sees a bright future ahead; is an optimist; lives an interesting, exciting life; and enjoys the things he or she is doing. Here are the means by race/ethnicity:

Mean well-being score

White 8.95
Black 9.47*
Amerindian 9.08
Asian 9.50
Mexican 9.06

*significantly higher than whites
