The Federal Reserve publishes a spreadsheet called dfa-generation-levels.csv. It is not the kind of document anyone reads for pleasure. But buried inside it is a comparison that, once you see it, is difficult to stop thinking about. In 1989, Baby Boomers were between 25 and 43 years old and held 19.5 percent of all US household wealth. In 2024, Millennials were between 28 and 43 and held 10 percent. Same age bracket. The total wealth of the country had grown from $20.8 trillion to $161 trillion between those two measurements. Millennials ended up with half of what Boomers had at the same point in life. The spreadsheet does not explain this. It just counts.
The DFA is not a survey with all the usual problems that come with asking people how much money they have. It computes household balance sheets from the bottom up; pension entitlements, business equity, financial assets, real estate, all of it; calibrated against the Federal Reserve's Survey of Consumer Finances and covering every household in the country. It is the most complete long-run picture of American household wealth that exists. The Federal Reserve uses it when it reports financial conditions to Congress. What it shows here is two lines moving in opposite directions for 35 years.
The Boomer line starts at 19.5 percent in 1989 and runs to 51.6 percent by late 2024, tracing the generation's movement through peak earning years and into the early edge of retirement. The Millennial line starts at essentially zero; Millennials were children when the dataset begins; and reaches 10.0 percent by late 2024. Two lines on the same base, going different directions, for 35 years.
The Compounding Machine
Percentages describe a distribution. Dollars describe what is actually at stake. In real 2025 dollars, Boomers held $10.7 trillion in net worth at year-end 1989. By late 2024 that figure had reached $85.2 trillion. Eight times larger, in inflation-adjusted terms, over 35 years, compounding at roughly 6 percent annually. That is not a rounding error. That is arithmetic applied at scale over time.
The mechanism behind the Boomer line is not complicated, just powerful at scale. A generation that hit its 30s and 40s during the long bull run of the 1980s bought homes at prices substantially lower in real terms than what would follow. They accumulated equity over decades. Their pension balances compounded through one of the longest periods of sustained market appreciation in postwar American history. Each gain became the starting point for the next. That is how a compounding system works; not in theory, but in the actual numbers.
Millennials began building measurable wealth in the mid-2000s. By 2005, the oldest were in their mid-20s and the generation's total real net worth had reached $0.4 trillion. By 2010, after the housing crash, $0.7 trillion. By 2020, $8.9 trillion. Fast growth throughout; but fast growth from a starting base orders of magnitude smaller than what Boomers had built from 1989 onward does not produce parity. You cannot compound your way from $0.4 trillion to $10 trillion in two decades. Not even in a good market.
The Year $11 Trillion Disappeared
The chart shows something that rarely comes up in coverage of the generational wealth gap. Boomer real wealth did not peak in 2024. It peaked in late 2021, at $88.7 trillion in today's dollars. Then, in a single year, the Federal Reserve's rate hikes removed $11.5 trillion from Boomer balance sheets. Eleven and a half trillion dollars. Roughly the size of the entire German economy. Gone in twelve months.
For Millennials, the same period barely registered. Real wealth edged from $13.0 trillion in late 2021 to $12.8 trillion in late 2022; a dip so small it barely shows on the same axis. By 2024 it had recovered and reached $16.5 trillion, the generation's highest recorded figure.
The asymmetry has a structural explanation. Boomers hold most of their wealth in equities and bonds; assets whose value falls when interest rates rise, because higher rates lower the present value of future cash flows. Millennials, at an earlier stage of accumulation and relatively more concentrated in real estate, held an asset class that retained its value far better through the rate cycle. The same policy that made homeownership harder for young buyers also happened to protect the real estate wealth of people who had already gotten in. Rate hikes punish the people who own the most of what becomes more expensive to buy. That was mostly Boomers.
Boomer real wealth peaked at $88.7 trillion in late 2021. In twelve months, $11.5 trillion of it was gone; roughly the size of the German economy. For Millennials, the same twelve months barely moved the needle.
The Only Comparison That Counts
Strip out time and the comparison is direct. In 1989, Baby Boomers at ages 25 to 43 held 19.5 percent of all US household wealth. In 2024, Millennials at ages 28 to 43 hold 10.0 percent. Those figures come directly from the DFA, anchored to year-end data in both periods. Not estimates. Not projections.
Put a dollar on it. Total US household wealth grew from $20.8 trillion in 1989 to $161 trillion by late 2024. If Millennials held the same proportional share Boomers held at the same life stage, their total wealth would sit at approximately $31 trillion. It is $16 trillion. The $15 trillion gap is the quantified cost of arriving later to a compounding system; on a base that was already built before most Millennials had anything to compound.
None of this requires a villain. Boomers accumulated over a longer time, at lower asset prices, through economic conditions that will not repeat. The DFA does not assign fault. It measures what happened to the money, quarter by quarter, for 35 years. And what it measures is a gap of nearly five to one between two generations comparable in size; at the exact moment one is beginning to spend down and the other is approaching its peak earning years.
The Debt That Wasn’t the Problem
There is a version of this story where Millennials are buried in debt and Boomers built their fortunes on cheap credit and nothing else. The DFA does not support it. At comparable life stages; Boomers in 1989, Millennials in 2024; both generations carried liabilities equal to roughly 32 percent of their total assets. Boomers: 31.3 percent. Millennials: 32.3 percent. One percentage point across 35 years. The debt burden, measured this way, is nearly identical. Whatever separates these two generations, it is not that one borrowed and one did not.
What is genuinely different is equity exposure. In 1989, Boomers held 6.6 percent of their assets in corporate equities and mutual funds. Millennials in 2024 hold 16.6 percent; a 10-point gap that traces directly to the spread of the 401(k) through the 1980s and 1990s. Automatic enrollment and employer matching put equity ownership within reach of middle-income workers in a way it had not been for most Boomers at the same age. Millennials became equity investors by default. Boomers largely had to opt in.
Boomers compensated through private business. In 1989, 12.8 percent of their assets sat in closely held companies, partnerships and self-employment capital. For Millennials in 2024 the figure is 8.2 percent. Running your own business was a more common route to wealth accumulation in that era than owning an index fund.
A higher equity percentage on a smaller base does not close the gap. Millennials hold $3.9 trillion in equities. Boomers hold $26 trillion. The structure of Millennial wealth is arguably more diversified. The absolute scale is not. And in a compounding system, absolute scale is most of what matters. What 35 years of quarterly Federal Reserve data establish is the shape of what happened: capital compounds on itself; time beats savings rate; a generation that entered the wealth-building phase during the longest bull market of the twentieth century accumulated accordingly. The generation that followed entered a system already running, at prices already elevated, on a base it had no part in building.
