Snap Shot Demographics

I found some quick statistics and demographics on the Philippines that can help paint a picture of the country. This is from Index Mundi's profile on the Philippines for 2011:

Children under the age of 5 years underweight
20.7% (2003) 

Obesity - adult prevalence rate
4.3% (2003)

My own quick observations from the stats above:

I think the contrast between underweight children under the age of 5 years old (20.7%) and the obesity rate in adults (4.3%) is rather interesting. Particularly in contrast to America where the obesity rates in both children and adults are rather high. Is it the Filipino diet and/or poverty that keeps the rate of children underweight high? How does the growing influence of American fast food and availability affect child nutrition after the age of 5 years old?

It's also interesting to see that 49% of the population lives in an urban center. Poor rural families are gradually moving into the urban city where resources are more readily available. What kind of resources are needed in rural areas? What kind of infrastructure is needed to provide for the sufficient needs of rural farm communities?

I also thought the age structure statistics was interesting. I would have expected high percentages of seniors over the age of 65 years old. Was there ever a baby boom in the Philippines like there was in the U.S. after WWII?
