Allow the CIA World Factbook to provide it:
Bangladesh
There are 150 million people in this land, living in an area the size of Iowa. Miraculously, if you want to call it that, 59% of the 133,000 square km of this land is arable. However, since they have allowed their population to get so damn big, they are supporting 2000 people per sq km of arable land.
This is 10 times as many as in the US and over twice that of its nearly equally screwed up fraternal twin Pakistan.
If you back-work the fertility rate of 29 live births per 1000 population, you get 4.4 million new arrivals per year, of which 60 per thousand die for whatever reason, so 265 thousand of these little ones are not making it. If they are saying 900 because of malnutrition, I can assure you that the reality is probably a lot worse than that. In the US it is 5 or 6 per thousand, and in Norway it is 3.5. There are about 4.2 million live births in the US every year, so there are more births in Pakistan, about the size of Iowa, than in the entire US.
This is yet another one of those places where 1/3 of the population right now is under 14, so the population is about to explode again.
I really like these population distribution graphs, because you can really tell what is going on in a country. In Bangladesh, there was a "baby bust" about 10 years ago, which caused a temporary decline in the number of births.
They have more than made up for lost time since then, though.
Amazingly, the life expectancy is over 60.
So, I would have to say that any food aid or anything else given to these characters is going to result directly in more people, because reproduction is what they do best.
