Background: In their pioneering research, Becker, Landes, and Michael (1977) found that beyond age 30 there is a positive relationship between women’s age at first marriage and marital instability. They interpreted this finding as a "poor-match effect" emerging when the biological clock begins to tick.
Objective: Our objective was to ascertain with more recent data whether or not there is evidence of a poor match effect and if so, whether it is associated with higher marital instability.
Methods: We used data on non-Hispanic white women from the 2006-2010 National Surveys of Family Growth (NSFG) (N = 3,184).
Results: We found evidence of the existence of a poor-match effect: women who delay marriage disproportionately make unconventional matches, which are generally associated with high marital instability. We also found, however, that their unions are very solid. Both of these results were consistent with earlier findings for the 1995 and 2002-2003 NSFG cycles. In attempting to explain this puzzle, we proposed and tested competing hypotheses. We found that the destabilizing effects associated with indicators of unconventional matches are also present in marriages contracted late, but are dwarfed by the stabilizing influences associated with higher levels of education and older ages.
Conclusions: This paper contributes to our understanding of the determinants of marital instability and the poor match effect by providing a new interpretation for the puzzle described above.
