The possibility of LEGO releasing minidolls based on DC characters has caused some to be concerned that LEGO will release less female minifigures based on licensed characters in the future.
I decided to do some research using BRICKSET in order to learn just how many female minifigures based on licensed characters LEGO has already released. Even if there are multiple versions of a character, I am only counting that character once.
Polybags, Juniors, sets that don't include minifigures, special combo sets and sets that haven't been released at the time of this writing have been excluded when tabulating the amount of sets containing female minifigures.
Since DC's news is what caused these concerns I'll start with them first.
DC: 8 female characters
Catwoman, Harley Quinn, Poison Ivy, Batgirl, Faora, Lois Lane, Supergirl, Wonder Woman
Female minifigures can be found in 13 out of 35 DC themed LEGO sets. Harley Quinn and Poison Ivy are tied for being in the most sets, which is 3.
MARVEL: 11 female characters
Black Widow, Gamora, Phoenix Jean Grey, Maria Hill, Mary Jane, Pepper Potts, Scarlet Witch, Spider- Woman, Storm, Nebula, Aunt May

Female minifigures can be found in 20 out of 51 HARRY POTTER themed LEGO sets. Hermione Granger has been in the most sets, which is 14.
STAR WARS: 21 female characters (I'm not familiar with the ENTIRE SW universe but I'm pretty sure I got them all and that these are all females)
Aayla Secura, Ahsoka Tano, Asajj Ventress, Aurra Sing, Barriss Offee, Boushh, Female Padawan, Hera Syndulla, Jedi Consular, Juno Eclipse, Luminara Unduli, Mon Mothma, Oola, Padme Amidala, Princess Leia, Sabine Wren, Satele Shan, Shaak Ti, Stass Allie, Sugi, Zam Wessell

THE SIMPSONS: 3 female characters

Marge Simpson appears in 2 out of 2 THE SIMPSONS themed LEGO sets.
THE LEGO MOVIE: 8 female characters (Unikitty doesn't count)
Cardio Carrie, Executive Ellen, Fabu Fan, Ice Cream Jo, Ma Cop, Rootbeer Belle, Sharon Shoehorn, Wyldstyle
Female minifigures appear in 12 out of 21 THE LEGO MOVIE themed LEGO sets. Wyldstyle is in 6.
SPEED RACER: Trixie is the only female minifigure appearing in 1 out of 4 SPEED RACER themed LEGO sets.
TOY STORY: Jessie is the only female character, appearing in 3 out of the 9 TS themed LEGO sets.
So there you have it. If my math is correct, altogether LEGO has released 80 different licensed female characters in minifigure form.
I have excluded Scooby Doo and Jurassic World because BRICKSET doesn't have the characters in their database yet.
I'm pretty certain that my facts are correct but I'm sure someone will tell me if I'm wrong somewhere. Hope this wasn't too hard to read. :}
