Kieron Barclay

Kieron Barclay is a postdoctoral researcher at the London School of Economics and at Stockholm University. His current work focuses on how the sibling constellation and other factors within the family of origin can affect later life outcomes such as educational attainment, cognitive ability in adulthood, labour market outcomes, marital stability, and mortality. In practice, this means examining the long-term impact of birth order, family size, the gender composition of the sibling group, birth intervals, and parental age at the time of birth. More generally, he is also working on several studies examining the impact of kin on mortality and has previously studied the potential influence of sex ratio imbalances on demographic outcomes.
