Malthus observed in his theory that population was growing

Malthus observed in his theory that population was growing in geometrical progression. This means that the population was increasing exponentially, with each generation having more children than the previous one. For example, if a population starts with 100 people and grows at a rate of 2% per year, after 10 years it will have increased to 122 people, but after 20 years it will have increased to 149 people, and after 30 years it will have increased to 181 people, and so on. Malthus believed that this exponential growth in population would eventually outstrip the resources available to support it, leading to poverty, famine, and other forms of social and economic unrest.
