Population Density Calculations
NAME:
Period:
Given the following Information, Calculate the Arithmetic and Physiological Population Densities.
FORMULAS: ARITHMETIC PD&gt; population / land = ARITH PD
PHYSIOLOGICAL&gt; population / arable land = PHYSIO PD
(to find the arable land percentage, multiply the total land by the percent, ie:
10 % = .1) (percent as a decimal)
***Remember: if working with millions and thousands, and you just divide the base numbers
(37.5 / 1050) without all the zeros, to move the decimal point over to the right 3 places!!!
1.
Country Total population:
37.5 million
Country total land area (sq/mi): 1056.6 (thousands sq mi) (1,056,600)
Country % arable land:
9%
APD: (population)___________ / (area)____________ =____________________ people per sq/mi
PPD: (population)___________ / (arable land)____________= _____________________ people
per sq/mi
(arable land %:
area
x percent
2.
Country Total population:
133.5 million
Country total land area (sq/mi): 51.7 (thousand sq mi)
Country % arable land:
73%
APD: (population)___________ / (area)____________ =__________________ people per sq/mi
PPD: (population)___________ / (arable land)____________= ___________________ people
per sq/mi
(arable land %:
area
x percent
3.
Country Total population:
16 million
Country total land area (sq/mi): 13.1 (thousands sq mi)
Country % arable land:
25%
APD: (population)___________ / (area)____________ =___________________ people per sq/mi
PPD: (population)___________ / (arable land)____________= ___________________ people
per sq/mi
(arable land %:
area
x percent
4.
Country Total population:
43.1 million
Country total land area (sq/mi): 401 (thousand sq mi)
Country % arable land:
4%
APD: (population)___________ / (area)____________ =___________________ people per sq/mi
PPD: (population)___________ / (arable land)____________= ____________________ people
per sq/mi
(arable land %:
area
x percent
a. CHALLENGE: Can you visually represent the data from country 4??? (Draw a map of
some kind?)
b. Now look at the PPT data chart, which country does each statistic represent.
