From this plot, we can know that the population grow faster and faster as it gets larger during this decade. And we can know that the percentage increase in population is unstable and increasing. According to the following calculation, we can know the Kazakhstan’s population of change percents is 8%.

23.94-23.83=0.11; 2^0.11=1.08; 1.08-1=0.08=8%
