Consider carefully when deciding whether to identify people by race. Often, it is an irrelevant factor and drawing unnecessary attention to someone’s race or ethnicity can be interpreted as bigotry. There are, per AP Style, occasions when race is pertinent:
In stories that involve significant, groundbreaking or historic events, such as being elected U.S. president, being named to the U.S. Supreme Court or other notable occurrences. Barack Obama was the first Black U.S. president. Sonia Sotomayor is the first Hispanic justice of the U.S. Supreme Court. Jeremy Lin is the first American-born NBA player of Chinese or Taiwanese descent.
