Hello, thank you for taking the time to post your question!
It depends on the full context of what you’re looking at! If this refers to human population, typically you would think of the opposite ends here as being concentrated and disperse. So highly concentrated would mean that there is a large amount of people per square mile and highly disperse would mean that people are more spread out.
Hopefully that gets you moving in the right direction! Feel free to reach out if you have any questions beyond that :)
