1 Population Distribution in Year 1 Michigan Geographic Alliance Carol Gersmehl & Marty Mater

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 2 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 ( Year 2000 The “worldmapper” website led us to data sources for Year 1. Year

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. 4

Data sources: Which regions had the highest percentages in Year 2000?

6 How would you describe the population distribution in the year 2000?

Data sources: 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

Notice the location of the 3 highest percentages in relation to the Tropic of Cancer. 9 Association

10 Why did some parts of the world have more people in Year 1? We will use other maps to investigate this question.

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? Notice the location of these largest ancient cities in relation to latitude (especially the Tropic of Cancer). _ _ _ _ _Tropic of Cancer _ _ _ _ _____Equator____ _North Pole_ 12 Association Pattern Comparison

Notice the location of these largest ancient cities in relation to Population of Regions in Year 1. 13

14 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).

Use the map about temperature, and color hot, cold, and in-between temperatures Color boxes with temperatures higher than 75 red or orange. 2. Color boxes with temperatures 45 or lower blue. 3. Color boxes with temperatures between 46 and 75 green.

In the map about temperature, we have turned on map layers that show color-coded temperature categories. 16 Describe the general locations of cold, mid, and hot temperatures in relation to latitude. Transition

After we find hot, cold, and in-between temperatures, we compare them to where people lived in Year Notice which temperatures match the general line of largest ancient cities. Association

After we find hot, cold, and in-between temperatures, we compare them to where people lived in Year 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? Association

19 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.

20 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. Assessment Options: Use the World Regions Basemap to:

21 Possible Extension: Use the Michigan Geograhic Alliance “Human Migration Countdown” clickable PDF to see the relatively late arrival of humans in the Americas.

Why do you think there were so few people in North America in the Year 1? 22

23 Another extension examines the relationship (association) between landcover, particularly land used for cropland, and population distribution. Is cropland available in the highest population regions?

24 Notice the small amount of cropland (lightest yellow) in Africa, South America, and Australia. Both South Asia and East Asia have areas of cropland.
