Google searches for ‘n-word’ associated with black mortality

UMD-led study first to link an Internet query-based measure of racism to death rates

A new study led by MPRC faculty associates David Chae and Sacoby Wilson is the first to examine an Internet-based measure of racism in relation to mortality risk. Researchers found that US geographical areas with greater levels of racism, as indexed by the proportion of Google searches containing the “n-word,” had higher mortality rates among blacks. "Racial disparities in health and disease represent a significant public health concern. Research suggests that racism is a major culprit that contributes to the gap in mortality between Blacks and Whites," said Chae. "Our study points to the utility of an Internet-search based measure to monitor racism at the area-level and assess its impact on mortality."

Most research examining the link between racism and health has relied on people self-reporting whether they had been the victims of racial discrimination. These measures, however, may not fully capture the extent of racism in a geographic area given that racist acts are often not committed overtly. "Contemporary forms of racism are more subtle, and people may not recognize that the social insults they experience are driven by discrimination or prejudice," Chae explained. "Discrimination is more insidious today. Racism in major societal domains, such as in housing, employment, and criminal justice contexts continues despite the existence of protective legislation."

The researchers looked at the volume of searches for the “n-word” ending in –er or –ers, and did not include those ending in –a or –as, since different forms of the word are used in different contexts. While not all searches containing the “n-word” are motivated by racism, areas with a greater concentration of these searches are likely to have higher levels of racism overall. The researchers wanted to examine whether this measure would predict differences in Black mortality rates across the country. They examined Black mortality rates in 196 media markets, which were compiled by the National Center for Health Statistics. Each one standard deviation increase in the level of area racism was related to an 8.2% greater all-cause Black mortality rate, which would be equivalent to over 30,000 deaths annually in the country. When they took into account additional demographic and socioeconomic characteristics of these areas, such as the number of Blacks, and levels of education and poverty, there remained a significant effect of area racism. The researchers also found significant associations between the Google measure of area racism and Black mortality from three of the four leading causes of death in this population--heart disease, cancer, and stroke.

"Racism is a social toxin that increases susceptibility to disease and generates racial disparities in health," said Chae. Racism has been shown to increase the risk of disease and poor health outcomes through several channels. For example, institutional forms of racism lead to systemic disadvantage, and segregate Blacks into health-damaging environments. As a source of stress, racism also has direct effects on mental and physical well-being. "These findings add to mounting evidence that population-level racial disparities in health are driven by racism," said Chae. "Racism represents a serious social and moral dilemma. The persistence of racial disparities in disease and mortality reflects the fact that issues of racism remain unresolved."
