FAQ
Reader questions
What does the 50th percentile represent for American households in 2018?
The 50th percentile, or median, indicates that half of U.S. households had net worth below roughly 97,900 USD in 2018, while the other half had net worth above that level, reflecting a pivotal dividing line in wealth distribution.
How does cost of living adjustment change percentile interpretation in 2018?
Applying regional cost-of-living adjustments shows that the same net worth threshold functions very differently in high-cost coastal metros versus lower-cost inland areas, altering mobility between percentiles for households year to year.
Why do people at the 75th percentile hold so much more than the median in 2018?
The 75th percentile households often combine home equity with diversified investments, whereas the median household is more exposed to housing cycles and carries higher debt loads, leading to substantially higher measured net worth near the top quarter.
What role did stock market performance play in 2018 net worth rankings?
Strong equity gains in 2017 and early 2018 boosted retirement balances for families with market exposure, helping many households cross threshold percentiles upward, while those without significant stock holdings saw more modest changes in measured net worth.
