The depicted line graph presents information on employment patterns across five different sectors between 1930 and 2010 in the U.S.A.
A glance at the graph reveals that most labor departments grew throughout the years, while the agricultural sector dropped.
It is explicitly observed that the agricultural industry, namely farming, fishing, and foresting, was prominent in the former half of the data. From 1930 to 1970, the employment rate was more than 60%. Starting from the latter year, it noticeably plunged, going from 30% in 1990 to plummeting under 10% in 2010.
However, it can be clearly observed that as the agricultural sector suffered, the other sectors flourished in the later years. The industrial and technical departments both similarly started incredibly slow and finally managed to reach over 20% in 1980 and 1990, respectively. While employment in the technical force grew gradually, the industrial force had a slightly steeper growth. Employee numbers in the sales and office department fluctuated in the earlier years and then experienced a slow increase. Other types of services had their highest point in 1940 with roughly 17%, but fell and stagnated.
