Employment to population ratio does not exclude anyone. It is the number of people divided by the number of people who are employed. It is also not 2016 anymore. The prime-age labor force participation rate has risen about a point since then.

Labor force participation rate is also not a measure of employment. It is the number of people who are employed plus the number of people who are actively looking for employment but who aren't employed. If you want strictly what portion of the population is currently working, that is employment to population ratio, which is what I posted.

That ratio varies significantly for African Americans, rural whites and African Americans and Hispanic women.
