Learning Targets
“I Can …”
-Define population density and contrast it to
population distribution and population range.
-Calculate the population density of an area.
-Explain how a high population density impacts
its members and their habitat.
Calculating Population Density
How are populations arranged within
a given space?
Population Range
• The area inhabited by a population
Population Distribution
• How individuals in a population are spaced
out across the range of the population
Population Density
• The number of individuals per unit area
• Your team is working for the fire department.
Your task is to analyze Room 4203 at MiltonUnion High School and calculate the
population density. The Fire Code states that
MUHS classrooms have a maximum capacity
of 0.40 students per square meter.
What you will do today…
• Measure the length and width of the
classroom to calculate its area.
• Determine the population density of the
classroom based on that area and the number
of people in the room.
• Change the size of the room to see how
population density is affected.
• Predict the population density of the class by
using the formula below:
POPULATION DENSITY= # OF PEOPLE/AREA
• Predict what will happen to population
density as you decrease the size of the room.
• Predict what kind of behaviors will occur as
you decrease the size of the room.
Experiment
1. Use a meter stick to measure the length and
width of the classroom.
2. Calculate the area of the classroom in square
meters.
3. Count the number of people in the
classroom.
4. Calculate the population density of your
classroom.
POPULATION DENSITY= # OF PEOPLE/AREA

Conclusion
What is your overall recommendation to the fire
department? In other words, does the
classroom meet fire code? What number of
people in the room would exceed the fire code?
Conclusion
1. Most people in the United States live in
urban areas. One hundred and sixty five
million people live on about 91,605,000
square meters of land. Calculate the average
population density in this area.
2. List two problems that are greater in urban
areas than in other parts of the United
States.
