The pie charts compare the age structure of the populations of Brazil and Germany in 2000 and present projections for 2050. The populations are divided into three categories: youths aged 0-14, adults aged 15-64, and seniors aged 65 and over.
Overall, adults accounted for the largest proportion of the population in both countries in 2000 and are expected to remain the dominant group in 2050. However, both nations are projected to experience population ageing, with declining shares of young people and rising proportions of seniors. Germany, in particular, is predicted to have a significantly older population than Brazil.
In Brazil, adults made up the majority of the population in 2000, and although this proportion is expected to fall slightly by about 5% by 2050, it will still represent the largest group. Over the same period, the percentage of young people is projected to decrease markedly by approximately 23%. In contrast, the proportion of seniors is expected to increase moderately by around 8%.
A more substantial demographic shift is anticipated in Germany. The proportion of adults is forecast to decline by roughly 15% between 2000 and 2050. Meanwhile, the share of seniors is predicted to rise considerably, increasing by about 18% and forming a much larger segment of the population. By comparison, the youth population is expected to remain relatively stable, experiencing only a slight decrease of around 1%.
