Slum clearance is a way of getting rid of neighborhoods that have become rundown and unsafe. This can happen for a variety of reasons, like people moving away, poverty, or too much crime in the area. In the United States, the government sometimes steps in to clean up these neighborhoods. They might get rid of old buildings that don't meet safety standards, build new roads, or put in things like parks or community centers. The hope is that by doing this, it will make the area better and safer for people to live in.
