I have been trying to work on this - thank you for asking the question! - but it's a broad topic. Are you looking for information about a particular country, or in a particular area of life? I can broadly say "it's gotten much better" but that doesn't apply everywhere, and I can say "there's better communication with the internet so people know more about us" but that doesn't tell you about job discrimination. Your question is broad enough to be an entire book, I wonder if you can narrow it down per rule 3, "Ask Clear and Specific Questions, with Time and Place in Mind."
