Analysis of poverty dynamics based on large-scale survey data shows that there is limited mobility across the income distribution for most individuals and families. Some people may get better-off over the lifecourse, as their careers develop and wages rise, but overall most poor people do not become very rich and most rich people do not become very poor. Lone parents are at high risk of poverty in the UK, but this poverty risk is reduced for those who are in employment and who receive state financial support through Tax Credits to supplement their wages. This article reports on longitudinal qualitative research which has involved repeat interviews with lone mothers and their children over a period of three to four years. The analysis here explores the experiences of sustaining employment while living on a low, but complex, income and highlights the challenges faced in seeking financial security in this context.

This article argues that our understanding of income and poverty dynamics benefits from taking a life-cycle perspective. A person's age and family circumstances - the factors that shape their life cycle - affect the likelihood of experiencing key life events, such as partnership formation, having children, or retirement; this in turn affects their probability of experiencing rising, falling, or other income trajectories. Using ten waves of the British Household Panel Survey, we analyse the income trajectories of people at different stages in their lives in order to build a picture of income dynamics over the whole life cycle. We find that particular life events are closely associated with either rising or falling trajectories, but that there is considerable heterogeneity in income trajectories following these different events. Typically, individuals experiencing one of these life events are around twice as likely to experience a particular income trajectory, but most individuals will not follow the trajectory most commonly associated with that life event. This work improves our understanding of the financial impact of different life events and provides an indication of how effectively the welfare state cushions people against the potentially adverse impact of these events.

The benefits of a longitudinal or dynamic approach to research are now widely accepted. In recent years, the availability of such data continues to improve, covering administrative based sources (including population registers) as well as sample surveys. Further features of this research field include; (a) a growing recognition of the usefulness of qualitative approaches to the collection and analysis of longitudinal data, and (b) an emphasis on the policy implications from longitudinal analysis given analysts' increased familiarity with the technical challenges posed by such data. Theoretical developments have examined the concept of 'resilience', and continue to address questions of structure and agency and the unfolding of differentiated life-courses. [ABSTRACT FROM AUTHOR]
