When states with larger population are given larger number of representatives in congress this is called?

This is called "proportional representation." In the United States, the number of representatives each state has in Congress is determined by its population, as measured by the decennial census. This system aims to ensure that larger states have a greater voice in the legislative process, reflecting their higher number of constituents. As a result, states with smaller populations have fewer representatives, leading to a balance in representation based on population size.
