In addition, marked sociodemographic shifts in the US population are reminders that the stereotypical image of a traditional family, including a wage-earning father and a stay-at-home mother, is fading. In fact, there is no one picture of fatherhood in the United States today. Fathers may be in 1- or 2-parent families; they may be single, married, widowed, divorced, or cohabiting; they may be gay or straight; or they may become new fathers as adolescents or in mid-life. Fathers may raise their own children with 1 partner or with different partners, or may raise others' children as a social, step-, adoptive, or foster parent. They may be unemployed, work full time or part time, and may work inside or outside the home. Some live with their children, some live nearby, some live across the country, and some may be incarcerated. If social context has meaning for men's health, these multiple structural variations of fatherhood would be expected to affect men's health—but in ways that are only beginning to be understood.
