What percent of world population is farmers?

Subsidising farming may encourage people to remain on the land and obtain some income. This might be relevant to a third world country with many peasant farmers, but it may also be a consideration to more developed countries such as Poland. This has a very high unemployment rate, much farmland and retains a large rural population growing food for their own use. Price controls may be used to assist poor citizens. Many countries have used this method of welfare support as it delivers cheap food to the poorest without the need to assess people to give them financial aid.
