“The Principles of Population”

Theory of Population & Food

•Population grows geometrically (2,4,8,16,32).•Food grows arithmetically (1,2,3,4,5,6).•If population not kept in check famine & disease would result.•SOL did not fall in 19th C but his ideas were more relevant in the population explosion of the 20th C

Applied the Law of Diminishing Returns to

Land

•Best land taken up first, then next best, then inferior….•At each stage the amount of food is less than before.

Iron Law of Wages

An increase in wage above subsistence level

= increase in population= increase in supply of labour

=decrease in wage
