Would cost concerns keep you from having the number of children you want?

A new analysis finds the richest 1% of Americans have the highest share of households with three or more children, with about half of that group having three or more. About 40% of the rest of US households have that many children, a gap that raises questions for families weighing the cost of raising kids.

Why it matters

The analysis suggests family size is increasingly tied to income, and that many parents are not having the number of children they want because they cannot afford it. Child-rearing is a large, concentrated expense for many households, so cost is a central factor in family planning decisions.

The findings draw on Federal Reserve Survey of Consumer Finances data and a separate analysis of households with three or more children by the Economic Security Project, a left-leaning nonprofit. Desired family size is measured separately through a 2025 Gallup poll, which found 42% of Americans would ideally like three or more children.

The players

Federal Reserve

The Federal Reserve is the central bank of the United States, and its Survey of Consumer Finances provides detailed household data used in economic and demographic research.

Economic Security Project

The Economic Security Project is a left-leaning nonprofit that conducted a separate analysis of households with three or more children.

Gallup

Gallup is a polling organization whose 2025 survey measured Americans' ideal family size.

The details

Higher-income households are more likely to have three or more children, a pattern the analysis links to the cost of child-rearing. The estimated $300,000 cost of raising a child in the US, not including college tuition, is a large expense relative to the $87,000 median family income. The top 1% earn at least $660,000 annually and hold a net worth of at least $13.7 million, placing them well above that median.

1980: Richer white mothers were less likely to have more children.
Around 2010: Rich women became more likely to have three children, a reversal of the earlier pattern.
2018: A study on white mothers' fertility by income was published.
2025: A Gallup poll on ideal family size was conducted.
November 3, 2026: The article reporting the income-fertility analysis was published.

Health Landscape

The analysis connects household income data from the Federal Reserve's Survey of Consumer Finances to fertility patterns, a link that has shifted since 1980 when richer white mothers were less likely to have more children. The current gap, with about half of the richest 1% having three or more children, reflects a reversal of that earlier pattern that began around 2010.

If cost is a factor in your family planning, the analysis suggests that many parents are having fewer children than they want. Discussing family size goals and financial stresses with your doctor or a counselor can help you weigh the practical and health considerations.

The takeaway

Family size is increasingly tied to household income, and the cost of raising children is a central factor for many families. Parents who want to plan their families can plan around child-care costs and bring their goals into conversations with a physician or financial advisor.
