We can predict a fair bit about Generation Alpha by analysing the demographics, which give us some forward forecasts: age of parents (older), cultural mix (more diverse), socioeconomics (slightly wealthier), family size (smaller), life expectancy (longer).
Then there is the research on their parents, the Millennials (or Generation Y) which gives us a sense of how they will be raised; more frequently moving and changing careers, materially endowed, technologically supplied and outsourcing aspects of parenting such as childcare.
Finally, there is the analysis of Generation Alpha themselves in their formative years, and we can learn a lot from this too; app-based play, increased screen time, shorter attention spans and digital literacy but less social formation.
