Baby Boomers Hold Half the World's Wealth and Are a Seventh of Its People
Boomers are about 14% of the population and hold about 50% of global wealth. Gen Alpha holds under 1%, and the $84 trillion transfer mostly skips a generation.
Baby Boomers hold roughly 50% of global wealth while making up about 14% of the population, and Generation Alpha holds under 1% — a gap that the projected $84 trillion transfer to 2048 narrows far less than it appears to.
Baby Boomers are about 14% of the world's population and hold about 50% of its wealth. That is the headline, and the more interesting numbers are underneath it.
The distribution
| Generation | Share of global wealth |
|---|---|
| Baby Boomers | ~50% |
| Generation X | ~28% |
| Millennials | ~14% |
| Generation Z | ~5% |
| Generation Alpha | under 1% |
| Generation Beta | effectively none |
The bottom of that table is not surprising and not a scandal — children have never held wealth. Every generation holds almost nothing at the age Alpha is now, and the Boomers held almost nothing in 1960.
The number worth arguing about is the top one, because it is not simply the result of having had longer to accumulate.
The transfer, and why it changes less than it looks
Roughly $84 trillion is projected to move between generations by 2048. It is routinely described as the largest wealth transfer in history and as the thing that will correct the imbalance above.
Two features of it complicate that.
It skips a generation, mostly. Industry estimates put the share reaching grandchildren at somewhere around 10–20%. The rest stops with the children. For Generation Alpha, whose grandparents are the Boomers holding the wealth, that is the relevant fraction.
It arrives late. Inheritance typically lands when the recipient is in their fifties or sixties. The years when money changes a life — a deposit, childcare, a career break — are two decades earlier. A transfer that corrects a balance sheet at 58 does not correct the decisions made at 32.
The number that actually moved
The starkest figure on this page is not about wealth at all. It is the ratio between what a house costs and what a person earns.
| Year | UK house price to income |
|---|---|
| 1997 | ~3.5× |
| 2025 | ~8.3× |
That ratio has roughly doubled in a generation. It is not a statement about anyone's character or spending, and it does not require a theory. The same asset now costs more than twice as many years of income as it did when the Millennials who are Generation Alpha's parents were children.
Against that, the cost of raising a child to eighteen is about $310,000 in the United States and around £260,000 in the United Kingdom — an expense that lands during exactly the years the ratio above is hardest.
What follows for the younger cohorts
The arithmetic is not a prediction. Wealth shares shift as cohorts age, and Generation Alpha will hold a substantial share by the 2060s simply by getting older. Anyone claiming this table shows a permanent settlement is over-reading it.
But two things in it are structural. The transfer mostly stops one generation short of Alpha, and the asset they will be buying costs twice the income multiple it did in 1997. Neither of those is fixed by waiting.
The useful version, for anyone planning around this cohort: Generation Alpha's spending power for the next fifteen years is entirely their parents' spending power. They hold under 1% of the wealth and the parent pays in every category, which is a point worth holding on to before reading anything about children as consumers.
