The graph below shows the proportions of workers in three different sectors in South Korea between 1981 and 2011. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The given graph illustrates the percentage of employees in three main fields, namely services, agriculture and industry in South Korean from 1981 to 2011 Overall, it is apparent that the employment share of services saw an upward trend over the course of 20 years and the opposite was true for agricultural workers, whereas the figure for industry remained relatively consistent in the same period. Moreover, the gaps widened from sector to sector toward the end of the period in question. Looking at the graph more closely, one can see that services sector started at the highest proportion among the three in question at approximately 40% then gradually went up before surged to 60%. It then peaked at roughly 70%, which accounted for almost three fourths of the graph. Started at the second highest position, agricultural employment then rapidly dropped to 20% after the first 10 years and slightly decreased by 5% before hit the lowest point at less than 10%, 7 times smaller than services in comparison. Last but not least was industry with a relatively consistent figure from 1981 to 2011. Having such a gradual rise in 1991, it then fell to around 30% in 2006 and continually reduced to less than it previous recorded percent and eventually finished at a second place.
