"Population, when unchecked, goes on doubling itself every 25 years or increases in a geometrical ratio"

This quote by Thomas Malthus is describing the exponential development of a population when it is not managed. He is suggesting that if a population is not checked, it will double itself every 25 years, or boost in a geometrical ratio. This implies that the population will grow at a progressively quicker rate, as each generation includes more people than the last. This can be seen in the population growth of lots of countries over the previous couple of centuries.

Malthus was concerned about the potential effects of untreated population development, such as a lack of resources and a failure to offer the population. He argued that population development should be managed in order to avoid these problems from taking place. This is why many nations have actually carried out policies to control population growth, such as birth control and household planning.

Malthus' quote is a suggestion of the significance of managing population growth in order to make sure that resources are available for everybody. It is likewise a caution of the possible effects of untreated population growth, and the need to do something about it to prevent it.
