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?
- Falling Mortality Rate. The primary (and perhaps most obvious) cause of population growth is an imbalance between births and deaths. …
- Underutilized Contraception. …
- Lack of Female Education. …
- Ecological Degradation. …
- Increased Conflicts. …
- Higher Risk of Disasters and Pandemics.
What are the 6 factors that affect population size?
- Economic development. …
- Education. …
- Quality of children. …
- Welfare payments/State pensions. …
- Social and cultural factors. …
- Availability of family planning. …
- Female labour market participation. …
- Death rates – Level of medical provision.
What are the five factors that affect population?
Population growth is based on four fundamental factors:
birth rate, death rate, immigration and emigration
.
- Heredity. Heredity is the transmission of physical characteristics from parents to children through their genes. …
- Environment. …
- Sex. …
- Exercise and Health. …
- Hormones. …
- Nutrition. …
- Familial Influence. …
- Geographical Influences.
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

Things that influence economic growth in production like:
natural resources, human capital, capital goods, entrepreneurship. GROSS DOMESTIC PRODUCT
. The total value of the goods and service that are produced in that country in one year.
- Natural Resources. The discovery of more natural resources like oil, or mineral deposits may boost economic growth as this shifts or increases the country’s Production Possibility Curve. …
- Physical Capital or Infrastructure. …
- Population or Labor. …
- Human Capital. …
- Technology. …
- Law.
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.
- Growth in cells.
- Growth in plants.
- Growth in animals.
