If the aim is to compare the figures reached in the two periods, the best mechanism is to calculate the growth in percentage(%). In order to do so, the formula showed in the photo has to be applied to each of the 3 variables analyzed, always placing the newest value in the position <em>V Present </em>and the oldest one in <em>V Past. </em>
Population % growth = ((132,000-120,000)/120,000 )*100= + 10%
Nº of workers % growth = ((86,250-84,000)/84,000)*100= +2.67%
GDP % growth =((6,220,800,000-5,760,000,000)5,760,000,000)/*100= + 8 %
