Recent research on the US opioid epidemic has focused on the white or total population and has largely been limited to data after 1999. However, understanding racial differences in long-term trends by opioid type may contribute to improving interventions. We analyzed age-standardized opioid mortality rates, by race and opioid type, for the US resident population from 1979 to 2015.

We present a model for estimating neonatal mortality rates for all countries. Neonatal mortality is an important indicator to track progess towards the Sustainable Development Goals. The model is used by the United Nations Inter-agency Group for Child Mortality Estimation.
Demographic Research

We present a Bayesian hierarchical model to estimate age-specific mortality at the subnational level. The model framework overcomes issues with estimating mortality in small populations, is flexible enough to be implemented in a wide variety of situations, and produces estimates of different measures of inequality across regions.

Some great people have compiled historical data on baby names into R packages for both the US (thanks to Hadley Wickham) and Australia (thanks to the Monash group). This makes answering all manner of baby-name-related questions easy. I was interested in looking at the distribution of baby names in these populations over time — that is, how concentrated are name choices in the most popular baby names? Is there a big difference between the number of babies that are called the most popular names compared to other names, or is the distribution more evenly spread?


Introduction This post looks at how variation in lifespan has evolved over time for different states in the US, and how this measure complements trends in life expectancy. I was inspired to write this after hearing a great talk by Alyson van Raalte last week at MPIDR and reading her latest paper on the topic. One of the most common aggregate measure of mortality we tend to look at is life expectancy.
