The word race has two main meanings:

1. A competition where people, animals, or vehicles try to reach a goal faster than others. In a foot race, runners sprint toward the finish line. In a bike race, cyclists pedal as fast as they can. Horse races, car races, and swimming races all test speed and endurance. When you race someone to the playground, you're both running to get there first. The winner of a race is whoever completes the course in the shortest time.
2. A group of people who share certain physical characteristics, like skin color, facial features, or hair texture. For centuries, people have been categorized into races like Black, White, Asian, and others. While these categories can seem obvious, scientists have shown that race is more of a social idea than a biological fact: there's actually more genetic variation within racial groups than between them. Still, race matters enormously in people's lives because of how societies have treated people differently based on it. The way someone experiences the world, the opportunities they receive, and how others perceive them can all be affected by their race. Understanding race means recognizing both that these categories aren't based on deep biological differences and that they've shaped history and continue to affect people's lives in real ways.
