Question 27 asks, why is a census, excuse me, key word here is census.
00:10
Why is a census? why is a census not always useful? so a census would give us really complete information.
00:17
A census means we're going to survey every single member of a population.
00:22
We do that in the united states every 10 years.
00:24
We try to get a hold of every single individual in the united states and ask them questions.
00:28
But why is that? not always the best thing to do.
00:33
So it's hard, right? let's be able to be a list specific reasons why you can't, why it's not always the best choice, why you would want to do samples instead of a census.
00:45
Okay.
00:46
So one is that it could take a lot of time.
00:48
It takes us well over a year probably to run the census every 10 years...
