By race/ethnicity (percent of children in single-parent families):
• Black or African American: Around 50-55% (historically high; recent sources indicate rates remain elevated, often cited near 50%+ for children living with single mothers).
• Hispanic or Latino: Around 40-42%.
• Non-Hispanic White: Around 15-20%.
• American Indian/Alaska Native: Often higher, around 50% in some breakdowns.
• Asian: Lowest, typically under 10-15%.
The key factor is religion or lack thereof.
Bingo! That is an unfortunate fact that bears heavily on the issue of fatherless families.
There was no doubt a spike in that number after both WWI and WW11, but accurately knowing the likely causes of the baseline is what is important.
IMO, more telling would be a comparative survey that identified the number of husband-fathers of the children in 1-parent families.
You just have to look at which states have the highest rates -- most of the southern states.
