         <p>Countries with higher income or consumption inequality tend to have more homicides per population. But looking at the relationship within each country's data, there does not seem to be a consistent relationship between inequality and homicide rates (that is, when there is a relationship in some countries, on average there is no evidence of such a relationship). This is an interesting multilevel or mixed-effects modelling problem that could easily trip one up.</p>
