> Expecting media to keep up with the exact demographics of the USA when the rate of change is so drastic, is a pretty high bar.
They don't have to 'keep up with' it all the time though, is 'do your research' and 'maybe visit the place' for the show you're writing about 'a pretty high bar'?
(I'm not even sure I agree it's important to reflect, or at least not that it's always necessarily required, but I certainly don't think it being difficult is the reason not to, because I don't see how it is.)
If the cast were 44% Asian, there wouldn't be an issue. It's less than 10%.
In 1990 in was 20% asian, in 1980 in was 7%. The representation of the show is still realistic for one person's lifetime, in my opinion.
Indeed the creators of the show were full adults in 1980, a time when the USA was still nearly 100% white in most areas.
