"Population, when unchecked, increases in a geometrical ratio"

This quote by Thomas Malthus is referring to the exponential growth of a population when it is not regulated. He is recommending that if the population is not kept in check, it will increase at a fast rate. This is due to the truth that the population will double in size with each generation, producing a geometric ratio. This implies that the population will grow at a quicker rate than the resources available to sustain it. This can result in a number of problems, such as overcrowding, food lacks, and an absence of resources. Malthus was concerned about the potential repercussions of unchecked population development and thought that it needs to be controlled in order to prevent these issues. He proposed a number of solutions, such as encouraging late marital relationship and reducing fertility rates, in order to keep the population in check.
