Hi Jaguars!Hi Jaguars!

We are starting a new unit today!

2

It is under the unit heading It is under the unit heading of people’s worldof people’s world

The lessons are:– A: What is population density and

distribution?– B: Where is world population growing?– C: One country’s way of controlling

population - China– D: Why do people move from one place to

another?– E: What is it like moving to another country?– F: Quiz- showing off our work etc

Where we are headed todayWhere we are headed todayFirst of all we will define a few termsThen we will look at a couple of maps that show where there are lots of people living and where there are only a few, and try and see if there is a patterns to all thisNext we will talk about some of the reasons why some places have different amounts of peoplesThen finally, go back and look at the why the population is high or low in particular places.You will need to make notes as we go, to be able to do the homework – if you have the ones I sent you printed out, this will be far easier than have to do your own – but you really do need to make notes of some sort.

Population density and Population density and distributiondistribution

Defining a few termsDefining a few terms

Population densityPopulation density is the number of people per square kilometrePopulation distributionPopulation distribution is how spread out people are across the Earth’s surface, Places with low population density (say 1 person per square kilometre) are said to be sparsely populatedsparsely populatedPlaces with a high population density are said to be densely populateddensely populatedWhat density do you think would qualify as high?

I think we would all agree that I think we would all agree that London is densely populatedLondon is densely populated

A thematic map is one that looks at one idea, like rainfall or the borders of countries or in this case population.A choropleth map is a kind of thematic mapChoropleth map is one which divided into areas that are shaded according to the measurement of the theme being displayed. This is a population choropleth map of London.

What would be your best guess?What would be your best guess?

What do you think the dark blue might stand for, in people per square kilometre? – More than 1000,– More than 2,500– More than 5,000,– More than 10,000, – More than 20,000 – More than 50,000?

Can you work out these Can you work out these population densities?population densities?

UK has a population of 58,000,000 and an area of 245,000 km2

France has a population of 58,000,000 and an area of 545,000Brazil has a population of 162,000,000 and an area of 8,400,000Australia has a population of 18,000,000 and an area of 7,618,000USA has a population of 266,000,000 and an area of 9,100,000China has a population of 1,300,000,000 and an area of 9,326,000

World Population Density – by World Population Density – by countrycountry

From the things we have just been discussing can anyone come up with country/part of the world that has high/low

population density and give a reason why.

Can we do any better now that we have Can we do any better now that we have thought about some of the factors that thought about some of the factors that

affect the population density?affect the population density?

HomeworkHomeworkHere is the same map againWhat can you remember about it?Since we last looked at this, we have been talking about reasons for why the population density is different from one place to anotherCan you give me some reasons why a place may be sparsely populated?Densely populated?
