While I understand the reasoning behind it to some degree, I must say that I find breaking down 'diversity' on a single scale to be a problem. It conflates a number of very different core issues, both from a continuity, political, and thematic perspective. While prejudice may indeed be applied globally without regard for actual classification differences, we cannot treat a proper representation of actual diversity the same way - simplification plays into the hands of those who wish to ignore the issue, as noted by the 'Saba as a female character approach' Star Wars doesn't have a single demographic slider, it has several. I count at least four. 1. Gender: Males vs. Females vs. Neuters This is probably the simplest to understand, since it most closely parallels the reader experience of human life and life on earth in gender. Star Wars, as a universe, is structured so that, in the overwhelming majority of cases, species are divided into two genders not simply biologically, but mentally as well, with hermaphroditic species such as Hutts generally adopting one gender or the other in society. There are very few, if any, truly neuter character options, even droids are programmed with gendered personalities. This slider also has the most obvious target value: 50:50. Since almost all species in Star Wars follow K-selected life strategies (small number of offspring, parental care, long life span), skewed gender ratios are uncommon, though not entirely absent. Species that did display strong behavioral differences of this nature would have different target values, but for the most part this can be assumed to even out on the galaxy wide scale and we can hope for a 1 to 1 experience. However, it should be noted that misogynistic tendencies have been documented from an in-universe perspective and certain cultural constructs, most obviously the Imperial military but expanding to a degree to all military units in general, have embedded prejudice. 2. Species: Humans vs. Near-Humans vs. Humanoids vs. True Aliens This gets complicated fast, but this is both the most significant, most complex, and most important form of diversity present in Star Wars. It is also, very critically, the one that involves the greatest internal differences in characters and one where real choices regarding viewpoints must be made. Non-human characters are just that not human. This goes beyond the physical to real differences in inherent psychology that change the way these beings think and as a result act. While this has not always been well portrayed, that's bad writing, not a diversity issue, and hardly unique to Star Wars. The take home message though is that certain types of aliens simply are not suited to center stage viewpoint roles because they are well, too alien. Portraying a Hutt, to pick an obvious example, as a viewpoint character would be an immense writing challenge especially considering that even the most 'mature' of Star Wars EU materials are aimed in part at teenagers. Such realities bleed into the demographics - the manifesto above makes a point that appearance shouldn't matter in the Galactic Alliance, and that's true, but mindset does matter, and, the further one gets from a human physical structure the less likely that the mindset is going to match with the norms of a universe created largely by a single species with a single physical setup. Form does, to a degree, dictate function. A hive species can't properly set up shop within a human city without redesigning everything around it, inherently ghettoizing itself no matter what society might want. What this means is that the target numbers for a diverse society of humans and aliens in Star Wars do not need to reflect the total diversity of aliens on every planet around every star in the galaxy, but only those species that are sufficiently adjusted to, and have chosen to try and, live amongst a mixed interstellar society. There will be many species that are simply too xenophobic, hostile, or otherwise alien to ever leave their home planets and have a peaceful existence (several references to the Unknown Regions have made this point explicitly in regards to the dangers of that region, there was no thousands of years of Republic to convince the Vagaari and their ilk to stay home or be destroyed). By the way, this undoubtedly includes some nasty human cultures, so we're not playing favorites or anything. That said, we really don't know what the targets are for the galaxy's demographics. My personal preference, reflected my own Star Wars writing is about 50:15:15:20, but that's little more than a guess. Some sort of concrete decision-making in this regard from LFL would be very helpful. 3. 'Race': Intra-species Diversity in Humans While humans are not the only species in Star Wars with internal ethnic divisions, they are really the only one were it matters to a great degree, largely because of out-of-universe concerns. Race apparently means little to nothing within the Star Wars universe, for while there is cultural prejudice among humans, it appears to be organized largely by planet and to ignore any physical traits. Character race then, becomes a reflection of the expectations of the readers and creators, based in the real-world cultural context. This is very different from species, as mentioned above, since differences between species involve real differences in both mental state and physical capability (ex. Wookiee-level strength), while 'race' is a cosmetic construct bound up with human history and prejudice. Star Wars is a universe created by an America and written and produced largely by Americans, despite its global appeal. This is very important regarding its treatment of race. Firstly, the US is an ethnically diverse country, and this creates an expectation of diversity. If Star Wars was being published in Beijing, everyone would be Han Chinese and no one would care. Second, the US has a long and troubled history of ethnic conflict and prejudice, but that is skewed towards a single axis, Black vs. White, that no longer represents the demographics of a changing nation even if it still dominates the chatter. Third, the United States is undergoing a period of dramatic demographic change that continues to this day, making 'US equivalent diversity' a moving target which it is not clear how Star Wars, a property that dates to the mid-1970s should address. Fourth, in the United States, ethnicity is not distributed evenly over space, even though in the color-blind universe of Star Wars they presumably are. This creates mismatches between demographics and experiences, and as a result the experience and perspective of just about every individual in America, including our authors and the readers, does not match the demographic reality of the country as a whole. So what's the target? Here's the US by Race in 2010: White: 78.1%, Black: 13.1%, American Indian 1.2%, Asian 5.0%, Pacific Islander 0.2%, Two or more races 2.3%, Other 4.8%. Hispanic or Latino 16.7%, White, non-Hispanic 63.4% (Hispanic is a self-defined category, according to the US census, so the demographics of that grouping and vis-a-vis the white population are a mess). Now, here's US race in 1980: White, non-Hispanic 79.6%, Black 11.5%, American Indian 0.6%, Asian 1.5%, Other 0.3%, Hispanic 6.4% (in 1980, Hispanic was not seperated from racial identity as a category, yeah, it makes comparisons more complicated). Those are some pretty big differences, and it creates something of a catch-22 in-universe, follow changing demographic trends and you impact continuity, ignore them and you ignore representing diversity accurately. Take Asians as an example: the difference between being 1 out of every 100 humans and 1 out of every 20 humans is massive. So what do you do? I'm really not sure myself, probably following current trends is best, but that means older materials have to be evaluated differently than new ones, but that we should also keep in mind, as readers, that older authors grew up and lived in a different, less demographically diverse (and less integrated as well) United States. 4. Life-Type: Organic vs. Machine This essentially, is the droids issue. It's very complicated. By rights, within the Star Wars universe, droids should out-number organic sentients by a significant margin, though one varying drastically depending on technology level and degree of industrialization from one location to the next. However, we know that organic beings dominate the galaxy absolutely, to the point that free droid societies, when and if they come into being, are viewed as aberrations and indeed, dangerous threats to be exterminated. Even more significantly, droids exist on a vast continuum of both intelligence and capability. The most common droids are often the least intelligent (ie. the ubiquitous ASPs), and many models, such as power droids, aren't really capable of anything beyond specialized interaction with the humanoid world around them regardless of how many cognition upgrades they receive. There's also some key in-universe factors limiting the viability of droids as main characters. First, its Star Wars, almost every story involves martial conflict in some fashion. However, the universe has gone to great lengths to prove that, in the martial arena, droids simply don't measure up to organics. While the accuracy of this is ultimately debatable, this is a storytelling necessity, otherwise you're reduced to infighting among machine armies and the occasional Terminator-style anti-machine resistance. These are not the stories Star Wars is designed to tell, so droids have been pushed to the side. Secondly, the question of the 'rights' of sentient machines are muddled. Droids are, after all, not-quite all in the same way that organic beings are, in Star Wars this is made explicit via the Force, and a code of ethics that applies to organic beings that share certain commonalities, such as death via the destruction of the body, doesn't really apply to droids. Effectively immortal, vaguely understood combinations of hardware, software, and experience shouldn't be held to the same ethical standards as flesh and blood, but who knows what those standards are. It would be the central premise of a very ambitious science-fiction series to grapple with such issues and their implications (please see Ian M. Bank's Culture universe for an example), and Star Wars is not that series. As a result of the above, the proper abundance of droid characters in truly significant roles is a matter of considerable debate, and I don't see any real reason why author preference shouldn't win out. Okay, that was a lot to digest and I'll stop now before going further. The take home message is this: diversity issues in Star Wars are a lot more complicated than simply an over-abundance of White Male Humans, and I do not see the universe being well served by boiling the matter down to white men versus everything else. Too many white male humans is the symptom, its not the disease.
