No. You have appropriately answered this question. You can cutoff some unwanted points if you think it might be too much, but according to me it is perfect. They are relevant because you have used the statistics wherever it is needed and the information from reliable resources. You can use it even for studying for your exams. As well, I have noted another point that you have used advanced vocabulary for this. The text has beautifully covered all the points needed for, as an answer.
HOPE IT HELPS YOU!!!!
ALL THE BEST!!!!!!!!!!!!!!!! :)
