The World Family Map presents information on undernourishment for countries’ entire population rather than for
families with children specifically because the available data are limited. As it is, the data on undernourishment come
from the Food and Agriculture Organization (FAO) of the United Nations and the World Bank. 40 The FAO defines
undernourishment as “a state, lasting for at least one year, of inability to acquire enough food, defined as a level of food
intake insufficient to meet dietary energy requirements.
