But, I was wondering. Where do these percentages come from? Let's review some math.
A percentage is mathematically described as the part over the whole times 100. In this specific example it is the number of people that responded divided by the total number of people in the state times 100.
But wait, the purpose of the census is to count the total number of people in the state. How can the percent be calculated if the total number of people isn't even known?
One equation with two unknowns cannot be solved.
