Use this measure when marital states, marriage order, ages, and observation periods follow one consistent legal or survey definition.

By duration

Divorces in each completed year of marriage since the wedding, where index i holds durations from i to i+1 years.

Query year

Duration year to look up, zero-based.

Share %

Queried duration's divorces as a percentage of all divorces.

Modal year

Duration-year index with the highest divorce count.

Marriage, union, separation, divorce, and remarriage definitions vary across jurisdictions and surveys. Cross-population comparisons require compatible age ranges and treatment of consensual unions.

Complement the period indicator with cohort histories, union duration, or age-specific proportions. Legal marriage records and survey-based union measures may answer different questions and should remain separate.
