I'm assuming the question is actually thus:
"The top 20 undeveloped nations with the largest (absolute) population growth will account for what percentage of the total world population increase by 2025?"
One of the big problems is that "undeveloped" is very vague and subjective. I'm going to answer as if "undeveloped" means any country OTHER than the fully developed ones; which means all counties other than the following:
By excluding those countries, you should then look at tables containing both the current population of countries, and the population growth rate of countries.
As a benchmark, total population as of now (2011) is just reaching 7 Billion. Estimated world population in 2025 is just over 8 Billion. Thus, we expect 1 Billion increase in the next 15 years (about 1.17% yearly rate).
In absolute terms, here are the top 25 countries, ranked by total population increase (numbers in parenthesis are population growth from 2010 to 2025, in millions):
If we exclude the United States from the above list (as a "developed" country), the top 20 list then accounts for 825 million, or about 80% of the total expected growth.
