Counting Couples: the Marriage Banns Registers of the City of Amsterdam, 1580–1810

Marriage is generally regarded as a decisive moment in the life course of individuals. As the social, but also the legal status of women and men changes as soon as they enter marriage and – by extension – their preceding wedding engagement, registers are and were being kept to record this life event in most societies. The difficulty in studying the long-term development of marriage patterns is the need for, among other things, detailed information about the marriage formation process. Most of the research on marriage patterns is based on a limited amount of data. Data either cover only a limited period (at most several consecutive decades), a limited number of variables, a relatively small number of marriages, and/or a relatively small town or region. The Amsterdam marriage banns registers are an exception to the above, in terms of content, focus area, and volume. In this article, we present the dataset results of the Citizen Science project ‘Ja, ik wil!’ [‘Yes, I do!’], involving over 500 participants retrieving a wide range of socio-economic data on over 94,000 couples from the rich source of the historical Amsterdam marriage banns registers, covering every fifth year between 1580 and 1810.
