We were trying to explain the Census to our 7-year-old son. They want to make sure they count everybody, we said, so they send a questionnaire to every home. We have to fill it out and send it back.
"So they want to know everyone in our family?" he asked. We said yes. "Cheddar too?" Cheddar is our dog. No, the Census does not ask about pets... but shouldn't it?
Just the day before, I had gone to see a new doctor. They sent me an online form to complete in advance, and they wanted to know if I lived with any pets. On an individual level, there was a clear medical interest in pets. The data would also be invaluable on the larger scale of the Census.
