Aims and ObjectivesPostdoctoral Fellowships • Build capacity in secondary analysis, promote use of large-scale data sets. • Publications/Dissemination to both academic/non-academic audiences. • Development of future proposals.
Context Postponement in timing of first births and increased lifetime childlessness – related aspects of recent demographic change. Population ageing and population decline: various implications, ranging from social security provision to issues of intergenerational support and the redefinition of familial obligations.
Data Sources Cohort Studies: NCDS/BCS70 Longitudinal studies, cohorts born in one week in March 1958/1970. To date six/five sweeps of interviews monitoring physical, educational, social and economic development. NCDS: most recent due end of June 2006 BCS70: most recent due end of April 2006
Aims of Data Analysis To examine factors associated with changing patterns in timing and propensity to childbirth among women in Britain: • Explore the socio-economic characteristics of women who remain childless in their early thirties. Consider similarities/differences over time. • Investigate the factors that influence the likelihood of experiencing lifetime childlessness.
Research Design Looking at women who remain childless in early 30s, comparing those born in 1958 with those born in 1970 Following those from NCDS subset over time, and comparing those with/without children at 46 (end of reproductive life). Methods: • Construct models to investigate the factors that influence cohort members postponement of fertility or lifetime childlessness. • Conduct regression analyses, including multiple linear and logistic regression, to examine the relationship between socio-economic factors and lifetime fertility.
