How often is the Census conducted for apportionment?

• A. Every ten years
• B. Every year
• C. Every two years
• D. Every twenty years

Answer: (A)

The main idea here is how often the population count that determines representation is conducted. The Constitution mandates a national census every ten years to tally the population and decide how many seats in the House each state should have. This decennial census yields the official totals used for apportionment, with congressional districts and seat allocation updated within that ten-year cycle. Other data-collection efforts by the Census Bureau happen more often for different purposes, but the counts used specifically for apportionment occur every ten years. So, the correct frequency is every ten years.
