Why is the Census important for congressional representation?

The Census is crucial for congressional representation because it directly impacts the distribution of congressional seats among the states. Every ten years, the Census counts the population of each state, and this data is used to determine how many representatives each state gets in the House of Representatives. States that experience population growth may gain additional seats, while states that see a decline may lose seats. This process ensures that representation in Congress reflects the current population distribution across the country, thereby maintaining a representative democracy where each person's voice is considered fairly in the legislative process.

In contrast, the other options do not accurately capture the primary purpose of the Census regarding congressional representation. While it is true that the Census can influence state budgets and provides essential data that can inform voting eligibility over time, these do not directly relate to how congressional seats are apportioned. Setting national laws is also outside the scope of the Census, as it serves primarily as a tool for understanding population dynamics rather than legislative function.
