[Dino and Coop singing]

00:13

What would the world look like without humans? [A busy street]

00:16

Well there would definitely be some upsides,

00:19

There would literally be more more fish in the sea. [Lots of fish]

00:21

Bigger rainforests.

00:23

More thriving wildlife. [Elephants]

00:25

No pollution.

00:26

No global warming.

00:27

No Kardashians. [Stop sign appears over a picture of the Kardashians]

00:29

But on the downside, the Earth wouldn't have...

00:31

Mount Rushmore!

00:32

So that's a fair trade off, right? [Picture of Mount Rushmore]

00:38

Well whether or not planet Earth would have been better off without us, we're here to

00:42

stay. For a while at least.

00:44

And that means we're here to be studied – by sociologists, psychologists, and even geographers. [Scientists watching people in cells]

00:50

That's right, because geography includes the study of the population that [Coop pointing at a blackboard]

00:53

lives in a particular location.

00:56

Population studies include the number of people in a location, majors towns and [Dino pointing at a blackboard]

01:00

cities, and specific data about the people that live there, like their age, gender and

01:05

type of home they have.

01:06

This information is collected by the U.S. Census Bureau through phone calls, surveys

01:10

and door-to-door visits,

01:11

if one of them approaches you with a questionnaire while you're having lunch at subway,

01:15

You should report them, they're not supposed to do that [Man about to eat his sandwich looks angry]

01:19

If a geographer were to look at population data about Alaska, they might find that as of 2012

01:24

the population was 731,449.

01:27

Alaska is the largest state in the U.S by land area, and only 1.2 people live in each [Man appears with a woolly hat]

01:33

square mile. Which means people can really blast their music without worrying about complaints [Guy in winter dress with his thumbs up next to a speaker wall]

01:38

Anyway a geographer could then compare Alaska to Hawaii, which had a population of 1,392,313

01:46

in 2012.

01:47

With a much smaller area composed of small islands, Hawaii has a wopping 211.8 people

01:55

per square mile. [Lots of people crowded together on a tiny island]

01:58

Still not downtown Manhattan but still more crowded than Alaska.

02:00

Washington, DC is the smallest of the three by size at only 68 square miles, but had a

02:06

2012 population of 632,323, which means that 9299 people live in each square mile of DC. [A huge crowd with people packed together]

02:17

And roughly 8000 of those are lobbyists." [Lobbyist holding sweets]

02:21

By analyzing population data, geographers can gain insight into how the physical geography,

02:26

climate and economy might impact changes in population.

02:30

For example, if the change in climate began to cause a particular area to have more

02:34

hurricanes than before, you could understand why the population might shrink as people [Guy with a briefcase is blown away]

02:39

to more comfortable safer and less blustery locations. [Guy sits down on the couch with his hair messy because of the wind]

02:43

Or the opening up a brand new gigantic factory which might encourage people to move nearby in order [Factory workers]

02:48

to get a job there.

02:49

There are plenty of other reasons related to climate, geography or economy – that

02:53

might cause individuals to move to or from a particular area. [Guy freezing in the snow wants to move to Florida]

02:56

Usually though it's not because thousands of people are trying to move closer to the Cold Stone creamery. [Big crowd appears outside the Cold Stone]

03:01

Although it's almost worth it. [Guy says he was he here first]
