The map below shows the world
hunger problem by showing the prevalence of
undernourishment in each country. Prevalence of
undernourishment is measured by the share of a
country's total population that is
undernourished. The higher the prevalence, the
more widespread the problem. To help analyse and
monitor progress, five prevalence categroies
have been established and are shown to the right
of this text.
The 5 prevalence categories used in the
