Demographic Facts College Students Should Know in 2026

There will be at test. (Updating a series that started in 2013.)

A young person recently asked me how I know all the things I claim to know. It’s hard to know where all this information in my head came from. You learn a lot of things by reading the news (actually reading, actual news; not watching short-form video by influencers you already agree with). You learn other things by reading research that either tells you facts of assumes you know them. It accumulates over the course of your life as a curious person who is motivated to understand the world.

But facts matter, and you need multiple ways to learn and remember them. Social statistics are flawed, of course, so we also need to know what is the best available data, and be aware of its strengths and weaknesses. With statistics, the point is to get beyond the impulse to judge numbers by whether they support our opinions. If all you know if “facts” that support your opinions, you are basically ignorant. Learn more. A common understanding matters, especially when we disagree with each other. You need real knowledge, whether I agree with you or not. And that includes demographic knowledge.

Basic knowledge supports deeper knowledge. Get some basic facts stuck in your brain, things that are not dependent on an internet search or chatbot prompt, but rather facts that you use to benchmark those things. Here is a start: some demographic facts to get you through the day without being grossly misled — or misleading others. This isn’t trivia that makes a point, or clicky statistics to shock and surprise you, but just the kind of information you need to make sense of our world. In keeping with the goal of incorporating orders of magnitude, I give credit to students if they are within 20% of the correct number. In the case of the US population — that means a number between anywhere between 274 million and 412 million!).

Feel free to add additional facts in the comments.

The numbers are rounded to reasonable units for easy memorization. All refer to the US and most recent available unless otherwise noted. Links to the sources below, along with a slide version.
