In developed countries, the labor
productivity of any commercial agriculture is
high, so only a very small percentage of the
population is involved with agriculture even
when agriculture is a major industry and export.
These countries focus more on manufacturing
and service industry. Agriculture or the primary
sectors of the economy have sizeable
contributions in the GDP of developing nations.
