The Latter-Day Saints (Mormons) provide a dramatic case study of the “public health” benefits resulting from involvement in a particular culture:
The Mormons have created a distinctive culture with remarkable health and welfare benefits. Utah, where 70% of the population are Mormon, has the lowest, or near the lowest, rates of smoking, lung cancer, heart disease, alcohol consumption, abortions, out-of-wedlock births, work-days missed due to illness, and the lowest child poverty rate in the country. Utah ranks highest in the nation in number of AP tests taken, number of AP tests passed, scientists produced per capita, percentage of households with personal computers, and proportion of income given to charity.
Utah is often ranked among the best places to live and the best places to raise children. Provo, more than 90% Mormon, was ranked by Self magazine as the healthiest city for women in the country, because it had the lowest incidence of cancer, violence, depression, etc.
Within Utah, it is clear that Mormons are disproportionately represented within these positive statistics, and Mormon populations outside Utah share similar phenomenally positive statistics. Indeed, although no academic researcher would dare to propose such a thing, one could conclude that a mass conversion to Mormonism would reduce social problems more effectively than all welfare spending, academic research, and public health initiatives in the last fifty years.
