Bryan L. Sykes’research focuses on demography and criminology, broadly defined, with
particular interests in fertility, mortality, population health, mass imprisonment,
social inequality, and research methodology. He applies and develops demographic,
statistical, and mixed methodologies to understand changing patterns of inequality
— nationally and abroad. Professor Sykes is currently collaborating on three projects.
The first project assesses how mass incarceration has affected measures of social
inequality and demographic processes (fertility, mortality, and morbidity) among subpopulations
with the highest risk of criminal justice contact in America, which has led to the
development of new demographic methods for multiple-partner fertility; new statistical
methods for estimating mortality in differential population environments; and new
sampling weights for national surveys that exclude marginal populations. The second
project investigates how national, regional, and global patterns of fertility, mortality,
morbidity, and injuries have changed over time. The final project is a multi-state
mixed-method data collection effort to assess the legal history and social consequences
of monetary sanctions across different jurisdictions within the United States, which
has led to new sampling methods for mixed-method and dual design studies.
