What query expression should I do for less than 20% American? Also, those with less than 40,000 dollars median income?

I'm somewhat confused with how to do query expressions. Would for both of these, would I use 'AND' or 'OR' in the query expression to combine them? Thanks!

You need to "AND' otherwise it will allow those who only qualify with one of those in your selection.

What data do you have? In case you have fields with counts per ethnic group, you will have to determine the percentage (Americans / sum of all ethnic group > 0.2) sand test against it, and as stated by Megan use the AND operator to filter on income.

Wouldn't it be a less than symbol instead of a greater than symbol? Simply due to the fact that that I want to exclude features with less than 20%?

Very true indeed. Good catch!
