Single mothers are women who are raising one or more children on their own, without the support of a partner or spouse. Research on single mothers often focuses on the challenges they face, including financial struggles, lack of social support, work-life balance issues, and the impact of single parenthood on children's well-being. Studies also examine the factors that contribute to single motherhood, such as divorce, separation, widowhood, or choosing to have a child without a partner. Researchers may explore interventions and programs that can support single mothers and their families, as well as policies that can help alleviate some of the challenges they face. Overall, research in this area aims to better understand the experiences of single mothers and improve outcomes for both them and their children.
