A setting of systematic disparities and restrictions; typically exists in the future or in fictional places.
It’s difficult to concretely categorize the settings of novels/movies as dystopias, because how each citizen of that society is affected by society as a whole is unique. Take the citizens of Panem (the fictional setting for The Hunger Games), for example. If you asked a Capitol resident whether or not they lived in a dystopian society, the answer would be “no”. Everyone they come into contact with seems to be well taken care of, and all seem to be living comfortable lives. However, if you ask a citizen of the districts, their answer would be much different. Because of this reason, I use the term “systematic disparity” to describe a dystopia – not everyone must be suffering in order for their society to be considered a dystopia. Another aspect that is often associated with a dystopia is the use of futuristic technology in order to reinforce the society’s status quo. It is because of this aspect that dystopias are often combined with the science fiction genre, creating dystopian science fiction. Dystopias often exist in the future, so it would make sense for new technology to have been developed in the time between now and the story’s time period.
To me, what differentiates between the genres of “dystopian literature” and “dystopian science fiction” is how prevalent that futuristic technology is in the story. Science fiction focuses on the technology and its use, while standard dystopian fiction may include it but not make it an important factor. Star Wars, for example, isn’t often touted as a dystopia, yet it shares many elements of a regular dystopia. This leads me to classify it as dystopian science fiction.
Replace these Storm Troopers with Peacekeepers and the Alliance’s logo with Panem’s and you could easily mistake this for a Hunger Games screencap http://www.starwarsnewsnet.com/2015/04/star-wars-celebration-anaheim-the-force-awakens-gets-a-new-trailer.html
Combining dystopia with the YA genre results in more relatable storylines. The YA genre is so popular because it isn’t limited to one age group; people of all ages can relate and enjoy the stories told in an easy-to-read YA format. Everyone over the typical age cap of the YA genre can relate to these YA storylines because they were young adults at one point in their lives as well. By utilizing universal experiences and feelings (whether it’s a first love, sibling relations, or competitions with others), YA dystopias make their more outlandish settings and problems more common and relatable. Because of this, they can reach a larger audience and have a bigger impact on the world. Utopian literature/media is made better because of its close association to the YA genre.
