Thanks for posting this question to my attention...much appreciated.
The IRS conducted a detailed review of available statistics on wealth
in a paper entitled "Personal Wealth, 1998", which can be seen here:
The paper identified a cluster of 6.5 million people in the US with
gross assets of $625,000 or more, and reports on the distribution of
those assets. [By the way, I spoke to one of the authors of the
report, who tells me an update is due this summer, though he wouldn't
specify a date].
The figures in the main text of the report break out assets by
particular categories, for example -- males with a net worth of under
However, the summary statistics for the entire population of wealthy
folks are presented in Table 1 of the Appendix.
In brief, the numbers for the 6.5 million wealthy in the US in 1998
break out as follows:
$11,142 million -- Total assets
$10,185 million -- Net assets (less debts)
$1,080 million -- personal residence
$1,531 million -- Investment real estate
$1,325 million -- Closely held stock
$2,709 million -- Other stocks
$ 633 million -- State/local bonds
$ 24 million -- Federal savings bonds
$ 239 million -- Other federal bonds
$ 96 million -- Corporate and foreign bonds
$ 39 million -- bond funds
$ 111 million -- unclassified mutual funds
$1,014 million -- cash and money markets
$ 291 million -- mortgages and notes
$ 221 million -- cash value life insurance
$ 264 million -- noncorporate business assets
$ 232 million -- limited partnerships
$1,017 million -- retirement assets
$ 310 million -- other assets
The paper provides similar breakouts within net worth categories, such
as all those with a net worth between $10-20 million.
No doubt, there have been some changes in these distributions since
1998. We'll have to wait until this summer to find out, I suppose.
Still, it's interesting to get a peek at how the other half (the other
5% is more like it) lives.
Let me know if there's anything else you need on this.
