Here’s is a list of “less heard” voices, or “voices that don’t get their fair share of attention” on Remembrance Day:
On Remembrance Day there are some voices that are “less heard than they should be.”
These are voices that don’t get their fair share of attention, and aren’t “represented” in the media as much as they should be represented.
In other words, they are “under-represented.”
Speaking precisely, this means that “the proportion of attention that they are getting” is less than (or “under”) “their proportion of the population.”
This website attempts to correct those disproportions by providing some of the under-represented voices with more of the attention they deserve (according to their proportion of the population).
