This author specializes in the historical demography of nineteenth- and early-twentieth-century Britain. Her work delves deeply into fertility behavior and mortality decline, with a growing interest in how migration flows impact demographic rates. Her research involves extensive transcription, cleaning, coding, linkage, and analysis of individual-level census and civil registration data, alongside other late-nineteenth and early-twentieth-century sources. Through these methods, she explores the factors influencing infant mortality and other demographic trends of the era.
In 1906, Sir George Newman's 'Infant Mortality: A Social Problem', one of the most important health studies of the twentieth century, was published. The volume argues that, even after 100 years of health programmes, scientific advances and medical interventions, early childhood mortality is still a significant social problem.
