The provided line graph aims to demonstrate information about the total proportion of income produced by the top 1 percent of the population between the years 1975 and 2015 in seven different nations: the United States, Canada, Italy, Germany, the United Kingdom, France, and Japan.
As is evident from the chart, most of the countries tend to increase their income over a 40-year timeframe. The United States is the country that increased sharply through the years and strengthened its major position, while France, Japan, and Italy are the three regions that rose gradually over the years.
According to the line graph, the United States rose slightly from 7 to 8% in the first 10-year period, before a huge jump to around 13% in 1985. After that, it tended to fluctuate in the next 10 years and peak at around 18% in 2015. In addition, Canada and Germany are two countries that shared a similar trend, which grew slightly in the first 20 years, then increased sharply to both 13%, approximately. The Uninted Kingdom’s proportion began at 10% in 1990 and finished at around 13% after a massive reduction in 2010.
Furthermore, France, Italy, and Japan are three regions that exchanged comparable trends, while three countries tended to reduce around 1-2% in the first decade, then fluctuated and rose moderately in the remaining period, which all made up for under 10% at the end of 2015.
