Employment Structure: The economy is divided into sectors. Since 1999 there have been major changes in Nigeria's industrial structure. Employment in agriculture (primary sector) has fallen due to the increasing use of farm machinery and better pay and conditions in other sectors of the economy. Industrialisation and economic growth (secondary sector) under a stable government have increased employment in oil production, manufacturing and industries such as construction, motor manufacturing, sugar refining, paper and pharmaceuticals. The growth of communications, retail and finance has increased employment I the tertiary sector. this means that Nigeria now has a more balanced economy, with an evener balance between the different sectors.
