"A new survey by Gallup, a polling organisation, appears to go some way to verifying Gary Becker’s theory. It asked 148,000 people in 142 countries about their perceptions of crime and how safe they feel across four measures: whether they trust the local police; whether they feel safe walking home alone; if they have had property or money stolen; and whether they have been assaulted over the past year. Testing the correlation between these questions and the amount of income inequality (as measured by the Gini coefficient) in any given country shows a strong and positive relationship.

Whether people feel safe walking home alone or not shows the strongest relationship with inequality. In Venezuela, for example, four-fifths of respondents said they do not feel safe walking home alone—kidnappings and extortion are a common occurrence in the country. Its income distribution is the 19th-most unequal in the study. In contrast, fully 95% of people in Norway said they feel safe walking home alone. Sure enough, it is 12th most equal country of the 142''.
