90% of single-parent families are headed by which gender?

The correct answer is female, as research consistently shows that a significant majority of single-parent families are led by women. Factors contributing to this trend include societal norms and economic realities that often leave women as the primary caregivers following separation or divorce. Women are more likely to have been custodial parents, receiving care for children while fulfilling work responsibilities. As a result, the structural support for single motherhood, including public policies, social services, and community resources, has increasingly been tailored to assist women in these roles. This context underscores the prevalence of female-headed single-parent families in society.
