I was scrolling through the contest page on Codeforces and it seems that div 3 contests tend to get more registrants than div 2 contests. It seemed odd. Has anyone looked into this?

What exactly is the difference between Div 3 and Div 2? The help page only mentions Div 1 and 2.

(Sorry I'm new here)

    Div 3 is rated for people below 1600 ratings

    Div 2 is rated for people below 2100 ratings

    You can read about their introduction here: https://codeforces.me/blog/entry/59228

    Also MikeMirzayanov I think the 'help' page on the codeforces bar alongside calendar needs updating, the FAQ from 10 years ago is fairly out of date.

Not surprising though. The number of greens and greys on cf are ever increasing and lately even starting div 2 problems have been quite novel, which is a good thing, but might discourage absolute beginners.

    I would have guessed there would be some people who prefer to do only div 3 instead of both div 3 and div 2 but this would be compensated by the blues and purples in div 2.

Always known trick. Division 3 inflated so, people who are eligible for Div 3 usually are scared to join Div 2 so they join Div 3. Those people, the moment they reach expert, they usually decrease in rating again and usually keep stuck for a while in that due to the difference in inflation between Div 2 and Div 3.
