Highlights

Scales of analysis are essential in human geography as they help in observing, thinking about data, and drawing conclusions.

There are four primary scales of analysis: global, regional, national, and local, each offering a different scope for studying geographical data.

The global scale considers data across the entire planet, making it the largest scale of analysis.

The regional scale focuses on large sections of the planet, such as regions like Afro-Eurasia or North America.

The national scale looks at data within a single country, such as France or Algeria.

The local scale is the smallest, examining data within a province, state, city, or even a neighborhood.

Different scales of analysis reveal different spatial patterns, emphasizing the importance of thinking spatially in human geography.

A map's scale of analysis can be tricky to define; for example, a world map with colored regions is at a regional scale, not a global one.

Analyzing data at different scales tells different stories, revealing patterns that might not be visible at another scale.

Globalization has made the global scale of analysis increasingly important, as the world becomes more connected through communication and transportation technologies.

Life expectancy data from 1950 to 2021 shows that people are living longer globally, with significant variations at regional and national scales.

At a regional scale, life expectancy differs significantly between regions, such as North America and Sub-Saharan Africa.

At a national scale, life expectancy can vary even between neighboring countries, as seen in East Asia and Southeast Asia.

At a local scale, life expectancy differences are observed within countries, such as between states in the United States.

Understanding why these spatial patterns exist at different scales is a key challenge for human geographers, who consider factors like wealth, urbanization, and development.

Transcripts

scales of analysis what in the fresh

heck are they and what do they reveal

maybe that's what this video is all

about so if you're ready to get them

brain cows milked well let's get to it

first of all let's define scales of

analysis analysis means observing and

thinking about data and then drawing

conclusions about it and then scale

indicates how large or small that data

set is in order to put it another way

how much or how little are you gonna get

thinky thinky about okay so when we're

in human geography as we are scales of

analysis indicate how much of the world

we're studying and there are basically

four scales of analysis you need to know

first there's the global scale which

considers data across the entire honking

planet and it's the largest of all the

scales and then there's the regional

scale which Zooms in on large chunks of

the planet known as regions like

afro-eurasia or North America Etc and

then there's the national scale which

considers data across a single country

like France or Algeria and then the

smallest scale is the local scale which

considers data within a province or a

state or a single City or even down to a

neighborhood okay now that's relatively

simple to understand right this map is

showing you a global scale this one a

regional scale this one a national scale

and this one a local scale that the AP

Human Geography overlords aren't going

to make things that easy so pay

attention here because you're often

going to have to define the scale of a

map on your exam and I cannot tell you

how many students think that they're

answering correctly when in fact they

are dead or wrong and they're going to

fail their test and drop out of school

and go live in a van down by the river

so look if you had to tell me what scale

we're looking at here then I hope you're

going to say Global because that is

correct well let's take that same map in

color in some regions and now what scale

are we looking at well if you still said

we're at a global scale then you're

wrong and if you listen very carefully

you can hear the AP Human Geography

overlords clinking their glasses and

giggling over your demise no even though

the map shows us the whole world the

scale of analysis here is regional which

is what these shapes here indicate or

one more example this is a map of East

Asia and Southeast Asia which in case

you don't know are names of regions so

what scale of analysis are we looking at

here Regional no not Regional look

they've got different countries colored

in and so the scale of analysis here is

National so be careful when you're

defining the scale of a map because it

can be tricky okay but let's be honest

who cares about different scales of

analysis you care my budding and

pubescent geographer and I'll tell you

why analyzing Geographic data at

different scales reveals different

spatial patterns and never forget that

thinking spatially is the Beating Heart

of the discipline of human geography

what I mean is different skills of

analysis reveal different patterns and

data or to say it another way different

scales tell different stories and let me

explain suppose we want to understand

how long people are living today which

is to say their life expectancy at

various scales so here you can see a map

of the world so the scale of the map is

anyone anyone yes it's Global but look

at all those countries colored in so the

scale of analysis is National dang

straight it's National but we want to

start by considering this data at the

global scale which is to say how does

life expectancy look across the whole

world and to be clear the global scale

of analysis has become increasingly

important in the last century because of

the increasing effects of globalization

and that just means that the world and

its people are becoming increasingly

connected through communication

Technologies like the internet and

transportation Technologies like

commercial airplanes Etc so compare this

global map depicting life expectancy

from 1950 to the this one from 2021 now

even though the scale of analysis is

National we can see that at a global

scale life expectancy has increased

basically everywhere but at a regional

scale here in North America we can see

that people are living a pretty long

life compared to another region say

sub-Saharan Africa where they live

significantly shorter lives and now

we're starting to get into the Intrigue

of various scales of analysis like oh do

you feel it we saw that at a global

scale people everywhere in the world are

living pretty much longer than they did

in 1950 but the spatial puzzle here is

this why do people living in this region

live longer than they did in 1950 while

people living in this region live much

much longer but I had a national scale

here in East Asia and Southeast Asia we

see that the spatial arrangement of life

expectancy varies considerably as well

in China they're just crushing it and

living about 78 years on average whereas

right next door in Myanmar their life

expectancy is about 13 years less again

why in the world would that be like

they're right next to each other and

then at a local scale we can see even

more spatial differences on this map

we'll Define local as by state and this

tells us that not everyone's life

expectancy in the United States is the

same in the western states like

California and Washington are living

longer than folks in southern states

like Alabama and Mississippi and then

you can get even localer and look at the

same data at a county level and see that

there are some places in Alabama where

they're living longer than people in

California county so the real question

that human geographers wrestle with at

these various scales is why these

spatial patterns exist like what

explains why these people live longer

than these people perhaps it correlates

with the relative wealth of the various

places or Urban versus rural areas or

the level of development or whatever but

the point is different scales of

analysis tell different stories all
