## Abstract

This paper presents an update to the previously published dataset known as prospective marriage and divorce data on Norwegian cohorts of two-sex marriages from 1886 until 2018. This update adds prospective data from all same-sex marriages formed in Norway between 1993 and 2018, with annual follow-up for 25 years, totaling 26 cohorts and 5,187 marriages. The data list the number of marriages that ended in divorce throughout each year of follow-up. The data contain information about the age of both spouses, the number of divorces from each cohort in the total population of marriages, as well as divorces among marriages formed in urban and rural areas of the country. Marriages formed within a calendar year are pooled into cohorts, and each pair is examined annually to ensure that the same two people remain married. As a result, the method is equivalent to the initial dataset on two-sex marriages presented in the first dataset.
