For many years, research has pointed to substantial differences between couples who practice Natural Family Planning (NFP) and couples who use artificial birth control. Using data collected from a sample of women in the United States of America who practice Natural Family Planning and comparing them to well-known national surveys, this study examined the effects of Natural Family Planning and artificial birth control on several dimensions of marital and family life. The study found that NFP women have lower rates of abortion and a dramatic low divorce rate (0.2%), than women in the national samples who use artificial birth control. The NFP women are more likely to be married and are more likely to recommend premarital chastity to young women. It was also interesting to note that couples who practice NFP had more marital relations, had more children and enjoyed greater happiness in their life than those using artificial birth control. The study also finds a high level of success in family life among NFP women, as well as a strong religious faith. Results support the hypothesis that Natural Family Planning is associated with positive spousal relationships and family stability. Interpretations of new data are discussed.
