The following appeared in a newsletter about health.
"The proportion of children in the United States who are overweight is greater now than ever before. Obesity rates among children have been increasing since the 1970's and, during that same time period, the proportion of children living in suburbs has increased. Whereas children in rural areas tend to have outdoor active chores and children in cities often walk to school or other places they need to go, children in suburbs are typically driven everywhere. Thus the increase in childhood obesity is probably due mainly to the suburbanization of America and the associated decrease in the opportunities children have for exercise."
