7. Populatin Dependency

Population Dependency

When a country has a high number of children, it is said to have a youthful population, but when a country has a high number of elderly people, it has an ageing population. both of these situations can give rise to a number of problems.

Dependency ratio: the ratio between those of working age and those of non-working age. This is calculated as:

% pop aged 0 -14 + % pop aged 65+

% of population aged 15-65

x 100

The ratio for an MEDC usually lies between 50 and 75. The ratio for an LEDC is typically higher. Mexico, with a youthful population structure, has a dependency ratio of 104. The higher the ratio, the greater the number of dependents that have to be provided for from the taxes on the workforce.
