Socioeconomic status
Socioeconomic status (SES) plays a significant role with education and learning, thus I think it should play a critical role in learner analysis. It can impact other demographic characteristics in this list including, Internet connectivity, access to technology, employment status, educational/grade level, etc. Numerous studies have correlated low SES levels with lower learning performance, low self-efficacy, stress, underrepresented backgrounds, and learning disabilities.
We're seeing a significant disparity in SES when it comes to STEM fields. In fact, one article/study I've seen cites low SES status as the biggest barrier to STEM.
