# Table 6 A summary of rates and decrements in the 7 state-duration model, United States Females, 2000–2005, ages 30 to 35

First decrements Subsequent decrements Total decrements Overall rate
m0 − > v0 2609 839 3448 .02573
v0 − > m0 2714 1886 4600 .11311
Over all durations:
Total number of marriages: 13,471
First marriages 8,103
Remarriages 5,368
Total number of divorces: 8,726
Ratio divorces/all marriages: .648
Ratio remarriages/all marriages: .398
1. Notes: Subsequent decrements are calculated by assuming that the product of duration zero divorce and remarriage rates is constant
2. The overall rate is all duration zero decrements divided by the appropriate total person-years of exposure. The person-years for first move divorces is (n/2)*(xm0 + ym1) = 102,447.5 and for subsequent divorces is (n/2)*ym0 = 31,580, totaling 134,027.5. The person-years for first move remarriages is (n/2)*(xv0 + yv1) = 23,570 and for subsequent remarriages is (n/2)*yv0 = 17,100, totaling 40,670
