Blended families usually get discussed in terms of feelings: how stepsiblings adjust, how a new stepparent earns trust, how holidays get split between households. New research shows there is a much colder number hiding underneath all of that emotional framing. According to Pew Research Center’s April 2026 analysis, the median net worth for households with children in blended families is $86,300, less than half the $194,400 median for households with children who are not in blended families. That is not a small gap. It is a wealth divide that tracks almost exactly with family structure, and it barely gets mentioned outside of academic research.
A Shrinking but Still Substantial Group
Pew’s data puts the share of U.S. children under 18 living in blended families at 17%, down from 23% in 2013, according to the same report. The decline is mostly driven by fewer children living with half-siblings rather than any major shift in stepparent households. Even with that drop, 17% is still roughly one in six American kids, which means this wealth gap is not a fringe statistical curiosity. It touches millions of households.

Where the Gap Actually Comes From
Pew’s analysis points to two structural factors doing most of the work behind that net worth difference. The first is education. Only 24% of children in blended families have a parent with a bachelor’s degree, compared to 53% in non-blended families, per Pew’s findings. Education tracks tightly with lifetime earnings, so a gap that wide at the parent level compounds into a very different financial trajectory for the household over time.
The second factor is housing. Blended families own homes at a lower rate than non-blended families, 55% versus 66%, and when they do own, they hold less equity in that home at the median: $132,000 compared to $195,000, according to Pew. Home equity is usually the single largest asset most American families hold, so a lower ownership rate combined with less equity per owner explains a large chunk of that overall net worth gap on its own.
Divorce, Remarriage, and the Math Nobody Runs
Part of what makes this gap so persistent is structural rather than personal. Blending a family almost always follows a divorce, a death, or a previous relationship ending, and each of those events tends to fracture household finances before they get rebuilt. A parent who owned a home with a former partner may sell it in a divorce and re-enter the housing market later, at a higher price, with less equity than they started with. Combining two households through remarriage does not automatically combine two sets of assets either; it often means combining two sets of financial obligations, including child support or alimony from a prior relationship, that a first-marriage household never has to account for. None of that shows up in conversations about how well stepsiblings are getting along, but it shapes the household just as much.
What This Means for Blended Families Today
None of this means blended families are worse off emotionally or that remarriage is a financial mistake. It means the financial rebuilding that follows a blended family’s formation deserves as much attention as the emotional rebuilding does, and right now it gets a fraction of it. Financial advisors, family counselors, and even the couples themselves tend to spend far more time on custody schedules and holiday logistics than on merging retirement accounts, refinancing a mortgage, or planning for a stepchild’s future the way they would for a biological one.
This gap is not new, either. Pew’s earlier work on stepfamilies, going back to its 2011 Portrait of Stepfamilies report, already found that stepfamilies were less likely than biological families to describe their finances as being in excellent or good shape, and less likely to say their family functioned very well overall. What the 2026 data adds is a hard dollar figure to a pattern researchers have been documenting for well over a decade. The emotional adjustment blended families go through has had a name and a body of research behind it for years. The financial one is only now getting the same level of scrutiny.
The Bottom Line
The emotional work of blending a family is real, and it deserves the attention it gets. But a wealth gap this wide, more than double between blended and non-blended households, suggests the financial side has been treated as an afterthought for too long. Closing that gap will take more than good intentions between stepparents and stepkids. It will take the same deliberate planning that any household rebuilding its finances from a fracture actually needs.
