The marriages still in the snapshot

ACS B12504 describes a current marriage among people who are now married or separated. Marriages that already ended are not part of this current-marriage population.

Long-lasting marriages have had more opportunity to remain in the snapshot. This is why the measure cannot answer how long a new marriage will last or the average time before divorce.
