There's no way to tell for certain who the most popular character is. The best way to get an impression of who is popular is from fan feedback, which seems to primarily accessed through the internet. It is - fan feedback - the reason why Tali is a romance option in the first place. Bioware originally considered Tali as a romance option in ME1 but decided not to reasoning that no one would like a completely suited girl with "chicken" feet, weird legs, and three fingers. They were surprised about how popular Tali was, especially among the male crowd, and decided to make her an option in ME2, to much praise.
The feedback option while playing ME2 while connected to live probably helps Bioware collect data on who is popular too as well. If I had to say, the data gained from that would have Miranda, Tali, and Jack as the most popular romance options, in that order.
