In the United States, the issue of single-mother parenthood is relatively common. Single mothers are usually one of three types; one type is the mother raising children after a divorce, one type is the unwed woman raising children by herself, and one type is the widow raising children after her husband passes-away. These three types of people are all vulnerable groups of society, and this is often a hot social issue.
