  • Daly and Wilson
    • Aim:
      • To find out if homicide rates would vary as a function of local life expectancy in Chicago which is divided into 77 neighbourhoods with stable boundaries and social and economic characteristics.
    • Methodology:
      • CORRELATIONAL study using survey data from police records, school records, local demographic records collected by population census.
    • Procedure:
      • Examined local communities in Chicago which had lower than average male life expectancies, ranging from 54.3 to 77.4 years.
      • Plotted various correlations between the data collected.
    • Results:
      • Life expectancy proved to be the best predictor of neighbourhood specific homicide rates which ranged from 1.3 to 156 homicides per 100,000 people per annum .
      • Young men discounted future and expected to live shorter lives so escalated the likelihood that they would INCREASE their risk-taking for SHORT-TERM rewards.
      • Neighbourhood-specific rate of absenteeism from school was NEGATIVELY correlated with life expectancy.
      • This explains why young men see little point in investing effort into school performance.
      • Truancy rates were examined and found that strong correlations with life expectancy.
      • Primary school truancy r = -0.50, n = 77, p = 0.001. High school truancy r = -0.32, n = 77, p = 0.001.
      • Parents unwilling to invest in child's education by enforcing attendance - operating on short time horizon.
    • New mothers 27.3 average in 10 longest expectancy neighbourhoods, 22.6 in lowest expectancy.
