This graph shows the change in the proportion of population aged 60 and above in 3 different countries; Korea, Spain, and USA. The data was collected for 100 years from the year 1950 to 2050. Each lines on the graph represents the different countries, blue line for Korea, light blue line for Spain, and red line for USA.
At the start of this data collection, USA had the largest number of people who are 60 and over. Spain was in the second place and Korea was after Spain.
However, over the years, the ranking has changed. Spain surpassed USA in between 1990 and 2010, and both of the countries showed the slow growth from that period. Korea lost its number from 1950 to 1970 but increased after1990, and in 2030, the population grew sharply and became the country with the largest number in 2050, leaving spain in the second place and USA in the third place.
