Which level is this? Is it GCSE core, additional, further additional, AS or A2? I would check on the internet for the exam paper and the corresponding mark scheme which could give you some pointers.

Population growth could be negative to signify population decrease from the year before.

Hi there, firstly what you do is work out the net death rate, so do 9.7-9.3 which gives you a death rate of 0.4 per thousand. Now work out how many people died during the year, so (60200000/1000)*0.4=24080. (You divide the population by 1000 as the death rate is per thousand). Now do the whole population - the number of people who died. 60200000-24080 which gives 60175920
