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.
the main things that effect population growth is weather that species finds a mate wether there is enough food and wether they have safe homes

The dramatic economic and population growth of Russia in the 18th century was the result of Russian leaders trying isolate Russia from Western European culture. The fight for conservation ended with Napoleon's invasions.
They did. Be resourceful, look it up yourself, don't be lazy like the rest of your generation.
The intrinsic growth rate of a population is the maximal rate at which the populatiom would grow under ideal conditions (i.e., unlimited resources, no competition, no predation, and no envionmental stress). In all real situations however, the population growth rate is kept in check by extrinsic factors.
it the availability of resources affects population growth BC if there are not enough resource, then more people will die and less will have children.
Economical Factors and Cultural Factors
biotic 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.
Booty
Location, amount of people, town.
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.
birth rate
The basic needs like food, shelter are some of the factors that affect the population's growth regardless of the size.
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.
