Where did people live in Year 1
and why in those places?
Essential Questions:
1. In Year 1, how was population distributed among world regions?
2. What might explain the regional distribution of population
in Year 1?
3. How does population distribution in Year 1 relate to
other topics?
- largest ancient cities (430 BCE, 100 CE)
- temperature
- latitude
The Michigan Geographic Alliance prepares lessons that
combine geography and history
for grades 6 and 7.

Our inquiry into
ancient
population
distributions started
with the “worldmapper”
website
(www.worldmapper.org).
The “worldmapper” website
led us
to data sources for Year 1.
3
We found population data for Year 1
for the regions shown on the map below,
but we will look first
at data for Year 2000 to become familiar
with the regions.

the population distribution
in the year 2000?

Here is data
for regions
in Year 1.

For each region,
place “counters”
on the world basemap
to show its
percentage
for Year 1.
Start with the highest
percentages.
(North America and
Australia & Oceania
each have less than 1% of the
world’s total population.)
7
Which regions have the 3 highest percentages?
Which regions have the 2 lowest percentages?
8
Association
Notice the location of the
3 highest percentages
in relation to
the Tropic of Cancer.
9
Why did some parts of the world
have more people in Year 1?
We will use other maps to
investigate this question.
10
First, we will use a map about large ancient cities.
We have turned on map layers that show the largest cities
in 430 BCE and in 100 CE and that show lines of latitude.
11
Notice the arrangement of these largest ancient cities.
Are they scattered evenly throughout the world?
Are they generally arranged in a line or band?
Pattern

Comparison

_____Equator____
Association
Notice the location of these largest ancient cities
in relation to latitude (especially the Tropic of Cancer).
12
Notice the location of these largest ancient cities
in relation to Population of Regions in Year 1.
13
Next, we will use a map about temperature.
We have turned on map layers about temperature
(Temperature text and Temp Activity)
and about latitude (Tropic of Cancer, Equator, Tropic of Capricorn).
14
Use the map about temperature,
and color hot, cold, and in-between temperatures.
2. Color boxes with temperatures 45 or lower blue.
1. Color boxes
with
temperatures
higher than 75
red or orange.
3. Color boxes
with temperatures
between 46 and 75
green.
15
In the map about temperature, we have turned on map layers
that show color-coded temperature categories.
Describe the general locations of cold,
mid, and hot temperatures in relation to
latitude.
Transition
16
After we find hot, cold, and in-between temperatures,
we compare them to where people lived in Year 1.
Notice which
temperatures
match the
general line of
largest ancient
cities.
Association
17
After we find hot, cold, and in-between temperatures,
we compare them to where people lived in Year 1.
Association
Notice which
temperatures
match the
locations of
regions that
had the
highest
percentages
In Year 1.
Can you think of
reasons to
explain why
colder regions
would have
fewer people in
Year 1?
18
We can also use the
GeoHistoGram.
x
Find Year 1 on the
GeoHistoGram,
and then find names
of civilizations
that had high percentages
in Year 1.
19
Assessment Options:
Use the World Regions Basemap to:
• Locate and name 3 regions that had the highest
population percentages in Year 1.
• Shade the latitude band that had that had most of
the largest cities in 430 BCE and 100 CE.
• Shade the latitude band that had “mid”
temperatures (rather than cold or hot).
• Write an explanatory paragraph to describe the
spatial association between population distribution
in the Year 1 and temperature.

Possible Extension:
Use the
Michigan Geograhic
Alliance
“Human Migration
Countdown”
clickable PDF
to see the relatively late
arrival of humans
in the Americas.
21
Why do you think there
were so few people in North
America in the Year 1?
22
Is cropland
available in the
highest
population
regions?
Another extension examines the relationship (association)
between landcover, particularly land used for cropland,
and population distribution.
23
Both South Asia
and East Asia
have areas of
cropland.
Notice the small amount of cropland (lightest yellow)
in Africa, South America, and Australia.
