structure means how the workforce is divided up between the three
main employment sectors - primary, secondary and tertiary. Employment
structures change over time.
in the early stage of development usually have a high percentage
of the population in primary employment. This is because most
people are engaged in agricultural activities.
a country begins to develop an industrial base there is an increase
in the secondary sector. An increase in machinery on farms means
fewer people are needed. People tend to migrate to urban areas
to get jos in factories.
a country becomes more economically developed there is a greater
demand for services such as education, health care and tourism.

machinery and robots replace people in the secondary sector hence
the decrease in secondary jobs.
