How persistent is elite wealth across American generations?
Core argument: Among grandchildren of grandfathers at the 100th wealth percentile, 13.5% reached the top 1%, compared with 9.9% at the 99.9th percentile, 3.7% at the 98th, and 1.9% at the 90th.
Using various wealth proxies and data tracking tens of millions of individuals, we find that most extremely wealthy individuals drop out of the top tail within their lifetimes. Yet, elite wealth still matters. We find a non-linear association between grandparental wealth and being in the top 1%, such that having a rich grandparent exponentially increases the likelihood of reaching the top 1%. Still, over 90% of the grandchildren of top 1% wealth grandfathers did not achieve that level. In our data, 1.9% of individuals with a grandfather at the 90th percentile ended up in the top 1%, which is double the average for the group. This percentage increases to 3.7% for those with grandfathers at the 98th percentile. For grandchildren of those at the 99.9th percentile, the percentage rises to 9.9%, and for those at the very top (100th percentile), it reaches 13.5%. Elite wealth, even within the top 1%, matters. However, the relationship is not deterministic. Even among grandchildren from the wealthiest backgrounds, the vast majority did not maintain a position in the top 1%.
