New York city.
NYC! There are probably tons of single women in NYC regardless of age. In NYC you probably have virtually an unlimited amount of meetups with literally any hobby or interest. By all means, I am not saying it is easy at all, but there most certainly are 100 of thousands of singles. I oftentimes wish I lived in a bigger city and still wonder if I should move because I feel like I have few dating options in my area since I am in my 30's. It is very difficult to find social events to go to where there are many people around my age. I feel trapped and hopeless about this. I feel like I will have virtually no choices in potential partners at this point and it is quite depressing.
