2025 civics test · Question 21 · System of Government

How many U.S. senators are there?

Official answer

  • One hundred (100)

What this means

There are 100 U.S. senators.

Every state gets exactly two senators, no matter how large or small its population. There are 50 states, so 50 × 2 = 100. Wyoming, with under 600,000 people, has the same two votes in the Senate as California, with nearly 40 million.

This was a deliberate compromise when the Constitution was written: the Senate gives every state equal weight, while the House of Representatives is based on population. Together they form the two chambers of Congress.

Answer: one hundred (100).

Why this is on the test

The number 100 comes from a rule written into the Constitution (two senators per state regardless of size), which is the point the question is really testing.
