The data shows that, in general, people have more children as they get older. However, there are also some differences between groups. For example, white women tend to have more children than black women. Additionally, the lines start to level off at around age 40, which suggests that most people have finished having children by that age.

Women tend to have more children than men. This is true for all three racial groups shown in the graph.

White women tend to have more children than black women. This is true at almost all ages.

Married couples tend to have more children than never-married, divorced, separated, or widowed individuals. This is true for both happy and not-too-happy individuals.

Happy people tend to have more children than not-too-happy people. This is true for all marital statuses.
