Washington, D.C., has the highest rate of stock market participation in the U.S., with 29% of tax returns from there reporting dividend or capital gains income in 2022, the year for which the most recent Internal Revenue Service (IRS) data is available, according to a Motley Fool analysis of that data. The District of Columbia’s stock market participation rate is more than double that of Mississippi, which has the lowest in the country at 11%.
Stock market participation by state is calculated by measuring the share of tax returns reporting dividend or capital gains income in a given year. Retirement account income is not included. This methodology was first used by researchers at the Federal Reserve Bank of St. Louis in 2017. It is a conservative estimate of actual state-level stock market participation, not a full count of investors. A separate Gallup survey puts overall U.S. stock ownership at 58%, more than double what this measure shows, because most of that 58% invest through a retirement account.
For individual investors, the long-standing gap in stock market participation between states highlights unequal exposure to decades of stock market gains and provides further insight into the distribution of stock ownership and its implications for wealth distribution.
Nationally, 21% of tax returns reported dividend income and 19% reported capital gains in 2022. Washington, D.C. led with reported dividend income at 29% and capital gains at 25%, while Mississippi came in at the bottom at 11% and 10%, respectively
In addition to the District of Columbia, these states led in reporting dividend income:
The states with the lowest percentage of their population reporting dividend income were:
The states with the highest percentage of residents reporting capital gains income, after Washington, D.C., were:
The states with the lowest share of residents reporting capital gains income were:
Median household income is a driver of differences in the rates at which states report stock market participation. Higher-income states have a higher share of residents reporting participation than lower-income states. D.C.’s median household income is nearly double Mississippi’s, but its median age is five years lower.
Washington, D.C.’s stock market participation also grew faster than any state from 2013 to 2022, by 7%. Washington state participation grew by 4%, California by 3%, and Colorado by 3%.
Overall, 48 out of 51 jurisdictions saw their stock market participation grow. Connecticut, Alaska, and West Virginia shrank by less than a percentage point.
The distinction between capital gains and dividends is important because they track different stock ownership events. Dividend income comes from stock, mutual fund, and REIT payouts, so it’s a fairly direct measure of stock ownership. Capital gains, as reported on a tax return, can come from selling any asset, including real estate or a business, not just stocks, so it’s a broader measure of income that may not be derived from selling a stock.
Median household income accounts for 61% of the difference in stock market participation among states, based on a regression analysis of IRS tax returns and Census Bureau income data. States with higher median incomes tend to have higher stock market participation rates, while states with lower incomes tend to have lower participation rates.
The median age of a state’s population has nearly no relationship to stock market participation as measured in this article, despite older Americans owning a higher percentage of stocks than younger ones, according to Motley Fool research.
There are some exceptions:
A simple state-level comparison can’t explain why some states have higher or lower participation relative to their median incomes. Income is a dominant factor in stock market participation, but not the only one. Other potential explanations range from financial habits to differences in access to employer-sponsored retirement plans, regional financial literacy, and more, none of which this data measures directly.
State-level stock market participation shows investment gains in the form of a dividend or sale of an asset that qualifies for capital gains tax – it is not a full measure of stock ownership. Living in a low-participation state does not mean residents don’t own stock. Many likely do so through a retirement account such as a 401(k) or an IRA, which aren’t captured in this ranking.
By that narrower measure, the gap between states is wide and, in the case of Washington, D.C., has been growing for at least a decade.
That income is a primary driver of differences in stock market participation across states isn’t surprising, given that the top 1% by net worth own more stocks than the bottom 90%, according to a Motley Fool analysis of Federal Reserve data. Adding a geographic dimension highlights how widespread that concentration is, and reveals where on the ground the divide is starkest.
Closing the stock market participation gap doesn’t require picking the right individual stock or timing an investment. For many households, the first step can be contributing to a retirement account or a low-cost index fund; the same approach countless other investors have used to start their own investing journeys that work best for them.
