Inspired by astronomyblog's Panel Show gender breakdown, I have compiled a Doctor Who gender breakdown.
The numbers refer to the number of appearances of characters with each gender. For each season I only count recurring characters once; For example, in season 1 The Doctor and Rose only count once each in the season average, but in each episode they count individually.
Seasons: The size of each bar represents the percentage of that characters with that gender in that season. I also give you the actual number.
Other/diverse: This category covers characters with no discernable gender (e.g. Autons, Daleks, computers, Weeping Angels) and the very rare occasion of a character identifying with both (e.g. Lady Cassandra O'Brien.Δ17). This does not include The Master who is counted as male for appearances as The Master and female for Missy.
The gender balance in Season 1 (2005) when Doctor Who came back to TV is the closest to equal of the last 10 years and worst (full) season is Season 8, where The Doctor's nemesis returns in a female body (spoilers!)
