Every year in the United States, hundreds of thousands of children rely on strangers to step in during the most unstable moments of their lives. These children enter foster care because of abuse, neglect, or family crises. But behind the numbers is a powerful and often overlooked truth:
A relatively small group of women is doing an extraordinary amount of the work.
From single mothers opening their homes to married women coordinating the daily realities of foster care, women make up the backbone of the foster parenting community in the United States. The statistics from recent years reveal just how central their role is.
The foster care system serves a staggering number of children.
According to national foster care data, “approximately 328,000 children were in foster care in the United States in 2024.”

Yet the number of families available to care for them is surprisingly small. Research shows that “there are roughly 184,000 foster households in the United States.”

When you compare these two numbers, it becomes clear that each foster family often supports multiple children over time, highlighting how critical every foster household is to the system.
Women play an outsized role in this system.
Research on foster parent demographics notes that “about 30% of foster homes are headed by single women.”

In addition, studies suggest that women represent roughly 70% of foster caregivers, either as single foster mothers or as the primary caregiver within married foster households.
Even in two-parent homes, women often coordinate the daily logistics of foster care—from school transitions to court hearings to medical appointments.
One of the most striking gender differences in foster care appears in adoption data.
Research examining adoption from foster care found that “only about 3% of adoptions were completed by single men.”

In contrast, single women adopt children from foster care at significantly higher rates, demonstrating how often women step into the role of permanent caregiver.
Another surprising pattern is that many foster families already have several children before fostering.
Research indicates that “50% of foster homes have three or more children in the household, compared with 21% of families nationally.”

This suggests many foster mothers are expanding already busy households to provide stability for children in need.
Contrary to some stereotypes, foster parents frequently have strong educational backgrounds.
Research on foster parent demographics shows that “70% of foster parents have education beyond high school.”

Many foster mothers bring professional experience in education, healthcare, or social services, which can help them navigate the complex emotional and logistical realities of fostering.
Another remarkable statistic highlights how concentrated foster care responsibilities can be.
A federal analysis found that “approximately 20% of foster parents provide between 60% and 80% of all foster placements.”

These highly dedicated caregivers often take in children repeatedly over the years, supporting dozens of placements throughout their time as foster parents.
The outcomes of foster care vary. Some children reunify with their families, others are adopted, and some eventually age out of the system.
Each year, “approximately 20,000 youth age out of foster care without a permanent family.”

Behind every outcome is a caregiver providing daily stability, support, and emotional safety.
And more often than not, that caregiver is a woman.
Across the United States, thousands of women quietly take on the responsibility of fostering—welcoming children into their homes during moments of instability and uncertainty.
They may not appear in headlines or policy reports, but their role is essential. We celebrate them this Women's History Month and every month.
