Noun

Groups that are and have been confined to a lower status in society due to the unfair structures created by society. Such a group is denied involvement in mainstream economic, political, cultural and social activities, resulting in inequitable outcomes.  

Use “structurally marginalized” communities and/or populations to be very clear that this a result of unfair and unjust systems. 

Instead of using terms like “disadvantaged”, “underprivileged” and/or “vulnerable” to describe communities that have been structurally marginalized, consider using “disinvested” and/or “under-resourced”.
