Does using a masking layer to exclude dots from certain areas delete those dots? Or does it place them elsewhere?

I am creating a dot density map and want to exclude certain areas (like the airport). If I use a masking layer, will that delete the dots that would fall in that area, or will it simply not place them in that area?

See this link:Is there a way to convert from polygon to points based on population of the polygon similar to dot d... If this solution helpful.

You can create polygon feature  for all areas that you want to dot density to be.

Thank you for your response! Do those dots not get represented then? Or are they simply placed elsewhere?

they aren't shuffled elsewhere if that is what you mean.  run a test and compare an area before and after masking to see what happens
