It provides a comprehensive overview of how the percentage of consumers in four nations changed throughout the surveyed timeframe. Overall, it is evident that the USA saw some fluctuations, eventually ending with a slight overall decline, while Western Europe and Japan saw a notable decline by the end of the trend. Additionally, the figures for China and the Middle East remained relatively stable, despite some minor oscillations in the middle of the timeframe.
Regarding USA consumers, the numbers reached a peak of nearly 10% in 2015 before falling back to 8%. Despite this growth, the figure decreased to 8% by the end of the period. In stark contrast, the proportion of Western Europe and Japan consumers experienced a dramatic slump, with figures plummeting to a record low of 2% in 2030.
In terms of consumers in China and the Middle East, a more erratic pattern can be observed. The figures show a steady rise before plateauing at approximately 3.5% for both countries in 2030.
