Let's break down the changes in employment and education for 16-17-year-olds over the years. It's quite a transformation. Back in the late '90s, the employment rate for this age group was at 48.1%. Jump to 2017-19, and that rate took a nosedive, plummeting to 25.4%.

So what are they doing instead of a Saturday job? Well the full-time education rate for 16-17-year-olds has only gone up by 15 percentage points during this time. So, it's not that everyone's spending all their time in school or college. They’re just less likely to be juggling work and studies compared to the past, choosing instead to focus on their education.

And for those who do decide to work while studying, the hours have shifted (though not dramatically). For those in school, weekly working hours dropped from 9.1 to 8.0 per week between the late '90s and 2017-19. If you're in college, it went from 11.8 to 10.5 hours per week. What's interesting is that most of the jobs for these young workers fall into three categories: waiters/waitresses, kitchen/catering assistants, and sales/retail assistants. They make up 52% of the workforce in this age group. Compare that to 39% for this age group two decades ago.
