Which is NOT an example of demographic information that can help bring value to your buyer persona research?

A buyer persona in HubSpot is built from details that help target groups and categorize contacts based on meaningful differences in needs, goals, behavior patterns, and demographics. HubSpot’s persona guidance explicitly includes demographics as part of persona creation, which makes factors like age, location, and income useful when they affect messaging, offers, and channel strategy. An unrelated physical measurement does not usually change how content is personalized or how a segment is targeted in HubSpot. That is why the non-marketing demographic outlier does not add practical value to persona research. HubSpot Knowledge Base+1
