Resources relative to the population, e.g. food, clean water, air
Threats relative to the population, e.g. presence of predators, disease, or environmental dangers
Reproductive effectiveness: how many offspring does each couple have, and do the offspring correctly fabricated (not too many genetic mutations) so they are survivable.
Presence of another species that wants the population to survive. For example, ants sometimes keep aphids as a source of food. Perhaps more close to home, humans keep a population of cows as a food source.

Population change refers to any increase or decrease in the size of a population, whereas population growth specifically refers to the overall increase in the population size over a given period, often expressed as a percentage. Population change can be influenced by factors such as births, deaths, immigration, and emigration, while population growth focuses on the net increase in population size resulting from these factors.
The natural growth rate refers to the rate of population growth excluding any factors such as migration. The overall growth rate, on the other hand, takes into account all factors affecting population change, including births, deaths, and migration.
As of 2011, the population of Cumnor in England was around 2,500. However, this number may have changed since then due to population growth or other factors.
Population growth is constrained by factors such as limited resources (food, water, land), disease, natural disasters, war, and access to healthcare. Additionally, social and cultural factors, government policies, and family planning practices can also influence population growth rates.
Economical Factors and Cultural Factors
The basic needs like food, shelter are some of the factors that affect the population's growth regardless of the size.
Zero population growth is a sign of a low birthrate. Other factors that affect population growth include a stagnant Death Rate and a low mortality age.
Location, amount of people, town.

competition for resources, predation, disease, and parasitism. These factors tend to have a stronger effect on population growth as population density increases.

The density dependent factor refers to the factors that affect the size or growth of a given population density. The factors also affect the mortality rate and the Birth Rate of a population. Some of the density dependent factors are disease, parasitism, availability of food and migration.

Economic factors, education and political stability are all some of the factors that affect population growth. Areas suffering from wars or famine, for example, will experience low population growth.
