User targeting during research phase

2 questions were raised here after seeing the below image online…

  1. When preparing to mood board, target, define users and embark on all manner of design research, do you shape your research on an individual, sub- group or collective group basis?

  2. Is it possible to design an outcome for the full diverse and inclusive collective that is being used to describe USA culture in online messaging? If so, What methods do you apply in your research?

This image was grabbed from a legal services website and labeled “diverse group hero” in the code to describe the firms customer targeting. On an art direction sub-note: Why is the individual wearing the green scarf not being embraced by anyone else in the photo?

iI think a legal services co might want to say the law applies to everyone/anyone. but there’s some folks missing from this list like wheelchair and kids etc.
for a mood board, your ‘target market’ should come from sales or marketing, and is broadly based on demographics or psychographics. college students usually do themselves as an easy way to get data points. You should be presenting an individual who represents the entire segment, a ‘persona’ - but this reply is pretty basic, why do you ask?

It appears to be a composite of maybe 3 groups.
