The line chart displays the proportion of income held by the top 1% earners in seven developed countries over their economic income throughout the 40-year period starting from 1975 and ending in 2015. It is apparent that the United States, whose line is blue, had the highest percentage in the last year, while France gained the least in the same year.
Beginning with the group of lowest data in 1975, Japan was the country where the economic share of wealthy people accounted for approximately 7.5%, and Italy’s figure was inconsiderably higher than Japan’s. Besides, the middle group, which included the US, Canada, and France, was not much higher when all values were around 8%. After 15 years of development, most of the data fluctuated a lot but seemed to remain unchanged, especially in Germany, with the numbers in 1990 at 10%, the same as the first phase of the interview. Noticeably, the US rapidly increased from 8% to 12.8% and discriminated entirely from the other countries.
In the last 25 years, every country has generally illustrated an upward trend. Additionally, after gaining the highest score in 1995, the United States escalated the percentages sharply until it finished with 18% in 2015. On the other hand, the UK’s proportions collapsed in the following years, subsequently reached a peak in 2010 at 15%, and then ended up with the same value. Canada and Germany followed the UK with similar figures in the final year while the remaining three countries, except the US, remained at the bottom of the table.
