From a UK perspective, I think Gen Alpha should start in 2016 or even in 2015
It really dawned on me this week that the last set of kids to start primary school in Autumn 2019 were those born between September 2014-August 2015. This means that they would have received some form of education (albeit very short).
Also, they could technically be the last to remember a time before the pandemic. At the same time, the last group to receive a whole year of primary school education would have been those born between September 2013-August 2014. With this in mind, should the start date of Gen Alpha be in 2015 or 2016. I’m personally leaning towards 2016.
