•The third most populous nation in the world, after China and India, the United States is the only major industrialized nation in which large population increases are projected.
•As of December 2, 2015, the United States has a total resident population of 322,267,564, making it the third most populous country in the world.
•It is very urbanized, with 81% residing in cities and suburbs as of 2014.
•In the 1800s the average woman had 7.04 children, by the 1900s this number had decreased to 3.56.Since the early 1970s the birth rate has been below the replacement rate of 2.1 with 1.86 children per woman in 2014.
•Foreign born immigration has caused the US population to continue its rapid increase with the foreign born population doubling from almost 20 million in 1990 to over 40 million in 2010, representing one third of the population increase.

Population GrowthThe worlds population is growing rapidly The population of the world is growing at an
exponential rate- its growing faster and faster.There are two things that affect the population size of the world:
When the birth rate is higher than the death rate, more people are being born than are dying, so the population growsThis is called Natural increaseWhen the death rate is higher than the birth rate it is called the natural decrease.
Birth rate- the number of live babies born per thousand of the population per year.Death rate-the number of deaths per thousand of the population per year.
Countries go through five stages of population growthThese are shown by the Demographic transition model (DTM)
Poorer, less developed countries are in the earlier stages of the DTM, whilst richer more developed countries are in the later stages.
Population growth and structureStage 1
• Birth rate is high because there's no use of contraception, and people have lots of children because many infants die.
• Death rate is high due to poor healthcare.
• Population growth rate is zero.• Population structure- life expectancy is
low, so the population is made up of mainly young people.Stage 2
• Birth rate is high because there's no use of contraception, Also the economy is based on agriculture so people have lots of children to work on farms.
• Death rate falls due to improved healthcare.
• Population growth rate is very high.• Population structure- life expectancy has
increased but there are still more young people than older people.
Stage 3• Birth rate is rapidly falling due to the
emancipation of women and better education.
• The use of contraception increases and more women work instead of having children.
• The economy also changes to manufacturing, so fewer children are needed to work on farms.
• Death rate falls due to more medical advances.
• Population growth rate is high• Population structure- more people are
living to be olderStage 4• Birth rate is low- people move to urban
areas , their wealth improves and they want more possessions. This means there is less money available for having children.
• Death rate is low and fluctuating.• Population growth rate is zero.• Population structure- life expectancy is
high, so even more people are living to be older.

Population Movements• Migration is the
movement of people from one area to another.
• When people move into an area its called emigration.
• When people leave an area its called emigration.
Migration happens because of push and pull factors
Push factors are the things about a persons place of origin that make them decide to move.
Pull factors are things about a persons destination that attracts them to it.
Example Push factors
• Not being able to find a job.
• Poor living conditions.
• Natural disasters
• Job opportunities
• Better standards of living

Immigration and emigration
Migration has positive and negative impactsPositive impacts Negative impacts
Source country • Reduced demand on services e.g. schools and hospitals
• Money is sent back to the source country by emigrants
• Labour shortage- its mostly people of working age that emigrate.
• Skills shortage – sometimes it’s the more highly educated people that emigrate.
• Ageing population- there's a high proportion of older people left
Receiving country
• Increased labour force- young people immigrate to find work.
• Migrant workers pay taxes that help to fund services
• Locals and immigrants compete for jobs- this can lead to tension and conflict.
• Increased demand for services e.g overcrowding in schools and hospitals
• Not all the money by immigrants is spent in the destination country- some is sent to their country of origin.
