Youth in Transition: Longitudinal comparisons of youth transitions in the UK using cohort and synthetic cohort data

博士项目题为：“青年转型：英国青年转型的纵向比较使用队列和合成队列数据”将利用已有的全国代表性纵向数据集，以便对关键确定的青年转型进行多元统计分析。在社会和经济环境下，个人性质的变化促使青年在从教育到就业、从住房到婚姻等许多领域的转变各不相同。与前几代人相比，甚至与他们的父辈相比，年轻人接受教育的时间更长，因此离开全职就业市场的时间也更长。离家居住以及婚前同居也变得越来越普遍。婚姻的概念已经改变了——今天的年轻人比以前的年轻人更晚结婚。婚姻并不是唯一被推迟的事情，个人决定要孩子的时间也被推迟了。与此同时，出生儿童的数量也在持续下降。所有这些例子都表明了一个共同的可识别的主题——个人青年生活过程中的关键点。这些关键点或过渡将构成这个博士项目的大部分内容。本研究旨在通过详细的比较队列分析确定、理解并最终解释这些关键的历史变化。国家儿童发展研究（1958年）和英国队列研究（1970年）提供了两个较早的出生队列研究的例子，提供了一个具有全国代表性的样本，支持比较分析的使用。然而，问题是，从英国队列研究的结束到千年队列研究（2000-2）的开始，存在着30年的巨大差距，这可能会阻碍一个旨在了解生命历程中这种历史性青年转变的项目。为了应对这一数据相关的挑战，本项目旨在构建来自英国家庭小组调查（1991-2009）和理解社会（也称为英国家庭纵向研究）（2009-）的青年数据的综合队列。结合这些综合数据以及年龄较大的出生队列，将用于实现本研究项目的目标。在历史和生命历程的背景下研究和理解青年的转变。

The doctoral project, titled: ''Youth in Transition: Longitudinal comparisons of youth transitions in the UK using cohort and synthetic cohort data''will make use of pre-existing nationally representative longitudinal datasets in order to produce multivariate statistical analysis of key identified youth transitions. The changing nature of individuals given social and economic circumstances promotes diverging youth transitions in many areas, ranging from education to employment, from housing to marriage. In comparison to previous generations, indeed even their parent's generation, young people are remaining in education longer, and thus out of the full-time employment market longer. Living away from home, as well as cohabiting with a partner before marriage are also becoming even more common. The very concept of marriage has altered-with the youth of today pushing back marriage much later than previous youth. Marriage is not the only thing that is being pushed back, the time individuals decide to have children themselves has also been pushed back. Alongside this the number of children being born is itself continuing to decline. All these examples demonstrate a common identifiable theme-key points within an individual's youth life course. These key points, or transitions will make up the bulk of this doctoral project. This research seeks to identify, understand, and finally explain these key historical changes that are identified through a detailed comparative cohort analysis. The National Child Development Study (1958) as well as the British Cohort Study (1970) offer two examples of older birth cohort studies that offer a nationally representative sample that supports the utilisation of comparative analyses. The issue however is that from the end of the British Cohort study and the commencement of the Millennium Cohort Study (2000-2) there is a large gap of 30 years that could impede a project seeking to understand such historical youth transitions within the life course. To combat this data related challenge this project aims to construct synthetic cohorts of youth data from the British Household Panel Survey (1991-2009) and Understanding Society (also known as the UK Household Longitudinal Study) (2009-). Combined, this synthetic data as well as the older birth cohorts will be used to achieve the aim of this research project. To study and understand youth transitions in a historical and life course context.
