All in all, people who are married have higher happiness ratings than unmarried. In addition, children effect the increase of happiness ratings in married couples.

Married people aged 18 to 29 become the happiest with 45 percent. The percentage of married people in the 30-49 group and the 65-over group are similliar. Unmarried people under sixty five years of age have low happiness ratings.

The happiness ratings of married couples are related to children that they have. Married couples who have children under 18 become the highest of happiness ratings. Married couples that have no children are happier than married couples that only have upper 18 years old children.
