World Human Patterns
Population Growth About years ago there were about 10 million people worldwide In 1950 the population started growing very quickly In the 1990’s the worlds population grew by around 80 million people a year It is estimated that in 2050 the population will have grown to about 9 billion people
Why the Increase? The major reason for population changes, whether in an individual country or for the whole world, is the change in birth and death rates. The birth rate is the number of live babies born in a year for every 1000 people in the total population. Death rates are number of people dying per 1000 people.
Natural Increase Uses a countries birth rate and death rate to measure a countries actual growth.
Why is the earths population Increasing? Infant mortality rate is decreasing Advanced medicine

Population Distribution and Density
Types of distribution Patterns Scattered- few people in a large area Clustered- Many people live in a small area Linear- arranged by a linear pattern, possible due to a lake or river (natural cause)
Population density A measure of how many people occupy an area of land Formula for pop.density: Population of country = people per km 2 Area in km 2
Example Population of Canada is 33 million Our area is 9,984,670 km2 Pop density = 33 million 9, 984, 670 km 2 = 3.30 people per km 2
Canada pop density = 3.79 per km 2 pop density= 1.77 per km 2 This is considered a low population density Japan pop density= 336 per km 2 England pop. Density = 116 per km 2 This is considered a high population density

Population Pyramids Shows the number of males and females within different age groups in the population. This information is displayed as an age-sex or population pyramid.
Less Developed Countries typically have a wide base and a narrow top. Represents a high birth rate and high death rate. Population pyramids of Developed Countries typically have a roughly equal distribution of population throughout the age groups.

Baby Boomers Canada's birthrate ballooned from the end of the Second World War until about 1965, thanks to improving economic conditions and a related trend over the same period toward larger families. The result was a 20-year bulge in the population known as the baby boom, a generation whose demographic influence has shaped Canada's economy and society and continues to do so as its members age and move into retirement.
Generations 2000/2001-Present - New Silent Generation or Generation Z Millennials or Generation Y Generation X Baby BoomBaby Boom
Many members of Generation Z are highly "connected," having had lifelong use of communication and media technology like the World Wide Web, instant messaging, text messaging, MP3 players, and mobile phones, earning them the nickname "digital natives".communicationWorld Wide Webinstant messagingtext messagingMP3 playersmobile phonesdigital natives
