This line chart shows the information about population growth from 1978 to 2009. To begin with, we can see that there are categories in comparison which are total growth, natural increase and net international migration. According to the graph, the population growth due to natural increase had started from 200 and kept almost constant during the time period. Last but not the least, the population growth due to net international migration had fluctuated during this period. In conclusion, it seems that net international migration has more effects to the total population growth.
