The 87th Academy Awards take place tonight. Here are six graphics that explain what you need to know about the award show -- from Best Picture locations and the Best Actress dress to the Best Actor's height.

1. Where to set your film if you want an Oscar


This map, created by Victor van Werkhooven, shows the settings of all of the films that won Best Picture at the Academy Awards between 1929, the year the Oscar was first awarded, and 2013.

New York’s gritty streets and Broadway stages have hosted the greatest number of Oscar winners, with 17 best pictures being set in the city. Of course, this probably reflects the huge number of movies that are set in New York overall. No Oscar winners have been set in South America, while the “Lord of the Rings: Return of the King” saved Oceania from obscurity in 2004.

2. If you win something at the Oscars, chances are you’re a middle-aged white guy


Hollywood has a diversity problem, and it is in full view in the Oscars. Niall McCarthy, a data journalist who writes for Forbes, created this infographic in partnership with Statista to track gender and racial diversity in the Oscars.

Seven of the 15 Academy Award categories have no female nominees at all -- visual effects, sound mixing, original screenplay, adapted screenplay, original score, directing and cinematography. The only fields where women dominate are costume design and production design.

Racial diversity is an even bigger problem. No non-white actors were nominated across the four acting categories. Out of 127 nominees, 118 are white and 9 are non-white, McCarthy writes, drawing on research by The Telegraph.

This lack of diversity can be traced back to the committee that selects the nominees. According to The Telegraph, the voting members of the Academy are 94 percent white, 77 percent male and have a median age of 62.

3. What to wear if you want to win the Best Actress award


Some of the dresses that the Best Actress winners have worn to the Oscars are nearly as iconic as the actresses themselves: Charlize Theron draped in shimmering Gucci in 2004, Gwyneth Paltrow in pink, spaghetti-strapped Ralph Lauren in 1999, or Audrey Hepburn in a a white Givenchy gown, cinched tight at the waist, in 1954.

In preparation for the 87th Academy Awards on Feb. 22, Mediarun Digital, a division of Big Group, designed this fascinating infographic that features 155 outfits of actresses who won the Best Actress Oscar from 46 different designers. You can see an interactive version of the feature, sortable by actress, decade, age, designer and color, here. Thanks to Mediarun for use of the image.

4. Oscars nominations and wins, charted


Data scientist Seth Kadish graphed the number of nominations and the number of Oscar wins for the films that have received 10 or more Oscar nominations – which is only 85 films in the history of the Oscars. The circles above correspond to the number of films that received a certain number of nominations and awards. Since there are 85 films in total, not all of them are labeled, but Kadish has labeled a few of the highlights.

"Titanic" remains the biggest Oscar winner of all time, with 14 Oscar nominations and 11 Oscars won. The biggest flops were “Gangs of New York,” “True Grit,” and “American Hustle,” all of which received a stunning 10 nominations but no actual awards. This year, none of the nominated films received more than 10 nominations: “Birdman” and “The Grand Budapest Hotel” each earned nine.

5. Hollywood’s top actors earn more than twice as much as the top actresses


One of the most recent surprises to come out of the Sony Pictures leak was the realization that Jennifer Lawrence and Amy Adams earned substantially less than their male co-stars for the film “American Hustle.” A leaked email between Sony executives revealed that Lawrence and Adams received a smaller percentage of back-end compensation from the film than director David O’Russell, Christian Bale, Bradley Cooper — even Jeremy Renner, who had a much smaller part in the film.

The graphic above, created by the New York Film Academy, shows the story doesn’t end there. The graph gives the earnings in millions of America’s ten highest-paid male actors and the ten highest-paid female actors in 2013. Angelina Jolie was the highest paid female actor with $33 million, roughly the same amount earned by the two lowest ranked men. The chart also suggests that age is a bigger factor for female actresses: Their median age is 34.8, while the median age for male actors is 46.5.

Part of the pay gap is undoubtedly due to women’s lower representation overall: Less than a third of speaking characters in the top 500 films between 2007 and 2012 were women, and only 10.7 percent of movies featured a balanced cast where half of the characters were female.

6. Hollywood likes its women tall, but the men are pretty average


Despite endless theories about height and the relative success of Hollywood figures, analysis of the heights of today’s top 10 grossing male actors shows the group only about 3 cm taller than average. It’s a different story for leading ladies however, with the top 10 women at the box office standing an average of 6 cm above the norm. The graphic above, courtesy of Flickograph, shows the data for 2013. Check out these particularly short box office favorites.
