By: Hirschl, Thomas A., Altobelli, Joyce, and Mark R. Rank.

Using income data from the Panel Study of Income Dynamics, this study finds that married indviduals are more likely to have a period of affluence than unmarried individuals, regardless of age.  At age 45, 33% of married individuals had experienced a period of affluence compared to 16% of unmarried individuals.  By age 65, 42% of married individuals had experienced affluence relative to 18% of unmarried individuals.  The percentage of married individuals experiencing a repeated period of affluence within five years of first affluence was 10% at age 45 and 22% at age 65 compared to 6% at age 45 and 7% at age 65 for unmarried individuals.  These trends hold when comparing across race, gender, and presence of children.
