Here are a pair of excerpts from ground-breaking study, indicating how "Research Links Childhood Lead Exposure to Changes in Violent Crime Rates Throughout the 20th Century" (p. 1, 2):
"Rick Nevin, the author of this study, reviewed extensive research demonstrating that childhood lead exposure reduces IQ levels later in life, and he examined other research showing a strong association between low IQ and criminal behavior. He then conducted a statistical analysis of United States crime rate data and lead consumption data to determine whether changes in population lead exposure could explain subsequent trends in violent crime."

"The Nevin study also examined the individual components of violent crime since 1960: aggravated assault, robbery, rape, and murder. For each of these components, and for the overall violent crime rate, Nevin tested the effect of childhood lead exposure and the effect of teen unemployment, the overall unemployment rate, and the proportion of the population in age brackets associated with higher crime rates (ages 15 to 25). Nevin’s statistical analysis found that childhood lead exposure explained 88% of the variation in the overall violent crime rate, while teen unemployment explained just 2%. The effect of overall unemployment and the proportion of the population in younger age brackets were found to be insignificant."
