sorted 4,600 volunteer families from high-poverty neighbourhoods into three groups: one received a voucher to move into a low poverty, more affluent neighbourhood; one group was offered a voucher with no restrictions on where it could be used; and the remaining group was the control. The movement of families to more affluent neighbourhoods was found to have no impact on adult income, at least in the short-term [viii]. The move to wealthier neighbourhoods did have some positive effects on mental health, and there were reductions in rates of violent crime for men and women, though property-related crime increased in males [ix]. The study of the "Moving to Opportunities" program did not consider if the low-income families had greater access to public resources when relocated in more affluent neighbourhoods, which Schoon predicts is a benefit of social mixing [x]. The services in a wealthy community will be services for the wealthy, and so they may not be useful to the low-income families that are supposed to benefit from them. The "Moving to Opportunities" program didn't increase the income of poor families, which suggests that, in the short-term, there isn't a transfer of wealth from rich to poor when both live in the same neighbourhood. This could be because the low-income neighbourhoods are mistaken for the cause of problems like unemployment, crime and poor health, while the neighbourhood is instead a symptom for those problems, a conclusion drawn by Bridge, Butler & Lees [xi].
