We carry history within us: Anti-Black racism and the legacy of lynchings on life expectancy in the U.S. South.

Abstract

The United States lags in life expectancy compared to most of the world's similarly wealthy nations, driven by pronounced regional disparities particularly between the South and the rest of the country. The U.S. South has a violent history of lynchings of Black Americans by White mobs after the ending of slavery and up to the Civil Rights Era. Building on critical race scholarship, the objective of this study was to determine whether there exists an association between historical lynchings and overall life expectancies in the U.S. South. We created a cross-sectional county-level data set with 1221 data points utilizing data from the Equal Justice Initiative and Robert Wood Johnson Foundation Country Health Rankings. The average life expectancy for 2019-2020 was 76.1 years, ranging from 68.2 years to 90.2 years. Overall life expectancy was found to be highest (76.6) in counties with no recorded lynchings, and lowest (75.5) in counties with the most lynchings (p<.001). In the spatially enabled regression model, the history of lynching along with other covariates explained 57.1% of the variance in life expectancies across the study area. Counties with a history of lynchings also score lower compared to the reference group in various socioeconomic indicators, including median household incomes and high school graduation rates. The findings suggest that lynchings were pivotal in creating the social and physical environment affecting health outcomes in the U.S. South today. We call for further public health research which acknowledges and explores this form of violent and institutional anti-Black racism as foundational to the nation's regional health disparities.
