Hey there,
does the sentence "over the last 7 years, the US-population has grown by 7%" mean that the US-population grew by 4% every year over the last 7 years? Otherwise it doesn't make sense in my opinion to calculate the number of 7 years old children by 4.67m * 1.04.
As I understood the sentence, comparing the US-population now and 7 years ago, today there are 4% more people. Therefore, we would calculate the annual growth by 4% / 7 years being 0.57% population growth per year and leading to a number of 7 year old children of 4.67 * 1.0057 = 4.7m.
Would appreciate if you could clear up my confusion!
Cheers
