Given that vast majority out of first unions were non-relationship when lifestyle to each other become (94.2%), i did not identify between relationship and you may low-marital partnership creation. The brand new follow-up to have CT went on 36 months following the date regarding relationship development, unless the new lady is actually censored earlier due to demise otherwise breakup (n = 88 971). To own splitting up feminine, we integrated the initial non-relationship (n = 201 647) otherwise and you will 2014.
