The divortiality is the ratio of divorces to the size of the population, observing the frequency and characteristics of divorces in this population. A transversal of the divortiality provides a measure - a snapshot - of a given year (usually a calendar year), across all generations.

The transversal indicators available are:  

The crude divorce rate is the total number of divorces recorded during the year in relation to the average permanent resident population. This indicator is shown by the number of divorces per thousand inhabitants.

This rate was stable until the middle of the 1960s. It then increased until stabilising at two divorces per 1000 inhabitants from 2011.

This shows the proportion of marriages dissolved by divorce across all levels of marriage length, indicating the divorce rate for the year in question.  The tendency to divorce has increased in recent decades. The short-term divorce rate indicator has risen considerably since 1970. Today an estimated two in five couples are set to divorce if current behaviour continues.

The longitudinal study observes divorces in relation to marriage cohorts, all marriages celebrated in the same calendar year, and in relation to a certain period of time (usually the length of the marriage). The longitudinal indicator available is the proportion of divorces by marriage cohort and by length of marriage.
