Already since the late 1970s China has a larger
population age 25 to 69 than all countries of Europe combined; and
India's population aged 25-69 surpassed all of Europe's in that age
group in the late 1990s.
With 1.5 billion population age 25 to 69 all other
countries combined have "only" about twice the population in that
age group than China.
By the middle of the 21st century China,
all of Europe, India, and the United States of America combined
will have less than 2.4 billion people age 25 to 69, while the rest
of the world will have more than 2.7 billion.
