Ratio of women:men using the service. Say there are 10 women and 30 men on the service, and each woman matches with 3 men. 30 matches total. Assuming equal distribution, the men have 1 match each. You can also then have a more extreme distribution. 3 of those men could have 10 matches and the other 27 have zero. Median man has zero matches, 80th percentile ("top 20%") has zero matches.
