“This student, like many others, isn’t just responding to an immediate economic calculation. He’s also caught in an invisible (and increasingly visible) demographic force: America is running out of people his age. Even if colleges fixed their cost and value proposition tomorrow — even if tuition dropped and job prospects improved — there would still be fewer students like him to fill seats. We are hitting peak 18-year-old, and the decline is just beginning.”
I believe peak supply of people in that age group. I.e for the up coming future there will be less and less students since there are just fewer kids
I believe the correct word to use is fewer in this case, since students are a finite countable thing. Sorry.
