The IRS does not collect or publish tax statistics by race

Evidence

When I hung up and got to work, I realized how easy it was to make that promise but how hard it would be to keep it. The Internal Revenue Service (IRS) does not collect or publish tax statistics by race—a seemingly basic fact that somehow I had never noticed before. … Yet we know nothing about taxpayers by race. — Dorothy A. Brown, The Whiteness of Wealth, 34

Categorization

• QUESTION: The deliberate hole in the data — IRS tax statistics by race — is the core structural problem this book builds around; worth chasing how the Census and other agencies do collect such data where the IRS does not.
• DEFINE: Establishes the central evidentiary absence the reader wants to track: no IRS data by race, forcing proxy-based detective work.
