Answer is 1355% increase from 1900 to 2000. prevoius poster has right numbers but forgot to move decimal to right to account for %. Remember when asked about percentage increase, if the number is doubled (76 million) that is a 100% increase. Anotherexample would be a 1000% increase would equal the amount 388 million. (38 * 100). Hope this helps.

Percentage increase = (pop. in 2000 - pop. in 1900) *100/pop in 1900
= (515 -38) x 10^ 6 *100/ 38 x 10^ 6= 1255.2% increase.
so you are not right.

1,355% increase
100 % would have been 76 million total

((515 000 000 - 38 000 000) / 38 000 000) * 100
= 1255.3 %
