Why there are so few girls closer to my age online on here compared to 2021?

I remember in 2021 on here I used to chat with so many girls around my age. I was 20 and I had a nice time here chatting with girls in the 18-27 age range. A lot of them were nice and sweet and I liked chatting with them. But nowadays I barely see any girls around my age here. A lot of females here are over a decade older than me nowadays and I am 21 now. Many of those girls with whom I used to chat don't come online at all. Only one 19 yr old girl chats with me here and that only happens in weekends and the other ones who chats with me are a 24 and a 26 yr old girl but they barely come online. I miss 2021.
