First marriages refer to marriages in which both spouses are marrying for the first time. Repeat marriages refer to marriages in which at least one spouse has previously been married. On this website, both series are shown in thousands and reflect annual marriage registrations.

These two measures help separate changes in overall marriage activity into different relationship pathways. First marriages capture new entries into marriage, while repeat marriages show how much of the total is driven by remarriage.

The chart contrasts the two series in a stacked area view so it is easy to see both their individual levels and how they combine over time. This makes it easier to spot periods when first marriages dominated overall registrations, when repeat marriages made up a larger share, and how the balance between the two changed across the longer trend.
