What factors determine the growth rate of a population? The two main factors affecting population growth are the birth rate (b) and death rate (d) . Population growth may also be affected by people coming into the population from somewhere else (immigration, i) or leaving the population for another area (emigration, e).
What are the 3 types of population growth?
- An exponential growth pattern (J curve) occurs in an ideal, unlimited environment.
- A logistic growth pattern (S curve) occurs when environmental pressures slow the rate of growth.
What are the five causes of population growth?

Definition. The growth rate of a value (GDP, turnover, wages, etc.) measures its change from one period to another (month, quarter, year) . It is very generally expressed as a percentage.
To calculate the growth rate, take the current value and subtract that from the previous value. Next, divide this difference by the previous value and multiply by 100 to get a percentage representation of the rate of growth.
There are three factors that influence population change: birth rate, death rate, and migration . Though one or two of these factors can influence a population in a particular area, all three impact population change.
There are two main models used to describe how population size changes over time: exponential growth and logistic growth .
Over the past 100 years, the study of environmental influences on human physical growth and development has focused on the influences of social and economic factors; family and household characteristics; urbanization/modernization; nutrition; and features of the physical environment such as altitude, temperature and ...
Genes involved in human growth consist of major growth genes and minor growth genes. Major growth genes have fundamental effects on human growth, and their mutations cause growth failure (or overgrowth) which are recognizable as single gene disorders .

Definition: The annual average rate of change of population size, for a given country, territory, or geographic area, during a specified period . It expresses the ratio between the annual increase in the population size and the total population for that year, usually multiplied by 100.
