Do Lottery Winners Really Go Broke? The 70% Statistic Nobody Can Find
The short version: the famous '70% of lottery winners go broke' has no study behind it. The US foundation it's usually attributed to said in 2018 that it isn't their research and can't be confirmed. Real data is less dramatic: in Florida, almost 2,000 of nearly 35,000 winners were linked to a bankruptcy within five years, and mid-size prizes postponed bankruptcy rather than preventing it; in Sweden, big winners stayed more satisfied with life for over a decade. The broke winners are just the ones who make the news.
Uncle Gary has a fact he deploys whenever someone mentions his eleven years of losing lottery tickets: "70% of lottery winners go broke within a few years anyway."
Aunt Linda asked where he read it. "Everywhere," said Gary, which was true. It's on news sites, in finance articles, in videos and on the side of at least one coffee mug.
By Gary's logic, by not winning for eleven years he has saved himself from ruin about 7 times in 10. He feels this deserves recognition.
Where the 70% comes from
The statistic is usually credited to the National Endowment for Financial Education, a US non-profit. In 2018 the foundation published a statement about it: the 70% figure is not backed by its research and cannot be confirmed by it. As far as it could tell, the number came from a remark by a participant at an expert meeting it held in 2001, and then took on a life of its own as articles repeated it and cited each other.
So the most famous number about lottery winners is a remark that was never a study. Every article that repeated it made the next one look better sourced. That's how a rumour gets a percent sign.
What real data says
There are real studies, and they are more interesting than the myth.
- Florida: economists matched nearly 35,000 winners of a Florida lottery game (1993 to 2002) with bankruptcy records. Almost 2,000 were linked to a bankruptcy within five years, roughly 1 in 18, nowhere near 7 in 10.
- Comparing winners of $50,000 to $150,000 with winners of under $10,000, the bigger prize made people less likely to go bankrupt straight away, but more likely three to five years later. The money postponed bankruptcy rather than preventing it, for people who were often already in financial trouble. Published in 2011 in The Review of Economics and Statistics.
- Sweden: a study of big prize winners, surveyed 5 to 22 years after winning, found they were more satisfied with their lives than similar people who didn't win, and the effect lasted more than a decade. Published in 2020 in The Review of Economic Studies.
So the honest answer to "do lottery winners go broke?" is: some do, a minority, and a mid-sized windfall doesn't fix deeper money problems. But most don't, and the big Swedish winners mostly seem to be doing fine.
Lottery winners who went bankrupt
Why you only hear about the broke ones
"Man wins millions, still has most of it, pays off mortgage" is not a headline. "Man wins millions, loses everything" is. The stories you've read were selected for drama, which is survivorship bias in reverse: the ones that crashed are the ones that survive into the news.
What's missing is the base rate: out of how many winners? A dozen dramatic stories out of hundreds of thousands of winners tells you about newspapers, not about winners.
How to check a statistic that's everywhere
1. Find the original. Not the article that quotes it, the study it came from. If every source points to another source, you're in a circle.
2. Ask "out of how many?". A percentage without a count and a group behind it is a mood, not a measurement.
3. Be suspicious of round, dramatic numbers. Real research tends to produce numbers like 5.7% with caveats. Rumours produce 70% with confidence.
Where it costs you money
Trading has its own famous statistics, such as the share of day traders who lose money. Some have real studies behind them; some are copied from article to article. Before you base a decision on one, or repeat it, check where it was measured, on whom, and over what period. That's the standard we hold our own myth tests to: every number has a source you can trace.
The moral
Linda showed Gary the 2018 statement. Gary read it twice, then said that if the 70% figure isn't real, his eleven years of not winning have protected him from nothing, and he wants them back. Linda pointed out that this is a sunk cost. Gary said he knows. He's read about it. Everywhere.
