The basic study of the family structures in Britain have surfaced that marriage and the changes in its setup have primarily been the cause of broken and loose family structures in Britain. More into this subject may be delved through an interdisciplinary approach where multiple disciplines of social sciences are mapped through to study the topic. The approach is nothing but the study of the same topic by viewing it through different angles. Of the various disciplines of social science that are available, this discussion has chosen to adopt three approaches, namely Anthropology, Sociology and Psychology. Once a brief of the different disciplines have been done these may be applied to the British societies and families. The first discipline deals with societies and cultures across the world, while the second deals with social relations and social changes in industrialised societies. The third discipline purely deals with the human mind.Marriage may be defined as the formal and legal unison of two individuals that is accepted by the society as a whole. It may also be considered as a formal agreement between two people that sets up obligations and rights amongst them and the ones revolving around their lives. From an anthropologic view, marriages have are a sacred ritual that have been accepted across societies and cultures and the rite of entry of the person into adulthood. The social status of the man and the women changes to husband and wife and marriage is the institution that binds them together in order to setup a family. Marriages in the UK and Britain have also been the same since decades but the previous half-century has witnessed conventional changes in this sanctified establishment.
