These animations visualize the dramatic
change in the age structures of China, Europe and the United States of
America between 1950 and 2050. In that 100-year period the population in
all three countries/regions will transform from young age composition to
an aging age structure. The process is particularly significant in China
and Europe. Surprisingly, the process of population aging is much less
dramatic in the United States of America than in China or Europe - both
due to higher fertility and a large number of (young) immigrants.
