Dataset of urban and rural same-sex marriages and divorces in Norway 1993 to 2018

The datasets contain cohort data on all same-sex marriages and legislations from 1993 to 2018, with annual follow-up for up to 25 years. 26 cohorts and 5187 male and female same-sex marriages in total.
The data displays the number of divorced marriages for each year of follow-up. The information is stored in two separate files.

The file Same-sex age contains information regarding the age and standard deviation of both partners in the year of their marriage. There are seven variables in the file. The first three characteristics determine the sample. Sample: urban, rural, and total; Category: 2 = same-sex women and 3 = same-sex men; Cohort: 1993 to 2018. The remaining four variables describe the ages of the sampled couples. Age1 and SD1 represent the age and standard deviation of the couple's senior member. Age2 and SD2 for the couple's youngest member.

The same three variables are used to define the sample in the file Same-sex divorce rate, followed by the number of marriages and divorces. Follow_up_year is the year of follow-up (0-25), and Accum_N_Divorced is the accumulated number of divorces in this sample, category and cohort at that year of follow-up. Accum_divorced is the Accum_N_Divorced devided by Population (the initial number of married in that cohort). Year_divorced is the Cohort added by Follow_up_year.

The paper, Same-sex Marriage over 26 years: Marriage and Divorce Trends in Rural and Urban Norway by Rune Zahl-Olsen and Frode Thuen, 2022, Journal of Family History, provides an illustration of how the data can be used.

本数据集涵盖自1993年至2018年间所有同性婚姻及其立法的队列数据，并对每个队列进行年度追踪，最长可达25年。数据集中包含26个队列，总计5187对男同性恋和女同性恋婚姻。数据展示了随时间推移每年的离婚婚姻数量，相关信息存储于两个独立的文件中。

在名为“同性婚姻年龄”的文件中，记录了双方伴侣在结婚年份的年龄及其标准差，共计七个变量。前三个变量用于确定样本特征：样本类型包括城市、乡村及总体；类别分为2（同性女性）和3（同性男性）；队列时间跨度为1993年至2018年。剩余四个变量描述了样本夫妇的年龄，其中Age1和SD1代表夫妇中年长成员的年龄及其标准差，Age2和SD2则对应夫妇中年轻成员的年龄及其标准差。

在“同性婚姻离婚率”文件中，采用与“同性婚姻年龄”文件相同的三个变量来定义样本，随后记录了婚姻和离婚的数量。Follow_up_year表示追踪的年份（0-25），而Accum_N_Divorced代表该样本、类别和队列在追踪年份的累计离婚数。Accum_divorced是Accum_N_Divorced除以Population（该队列中初始的婚姻数）的结果。Year_divorced则是通过Follow_up_year增加的队列年份。
