Parsing Science - Global decline of homicide

The global decline of births between 1990 and 2015 has led to a reduction in the proportion of people aged 15-29. So might this explain why the world’s homicide rate has dropped by nearly 20%. In episode 64, we’re joined by Mateus Rennó Santos from the University of South Florida, who talks with us about his research into how an aging population is a driving force behind the decline in homicide that countries in North America, Europe Asia, and Oceania have enjoyed over the past three decades. His article, “The contribution of age structure to the international homicide decline,” was published with Alexander Testa, Lauren Porter, and James Lynch on October 9th, 2019 in the open access journal PLOS One.
