Japan had a poll to rank the popularity of the characters in Fire Emblem: Awakening. These rankings are part of the Infobox Character template. For some reason, posters on GameFAQS like to bring the rankings up a lot.

You can find the poll results here.

Keep in mind when viewing the Infobox rankings that they were split into seperate rankings for male characters and female characters. So when you see Chrom and Lucina both sharing the ranking of #1, that it means that they were #1 in their respective gender rankings.
