AP HUMAN GEOGRAPHY Population Density Calculations NAME: Period: Given the following Information, Calculate the Arithmetic and Physiological Population Densities. FORMULAS: ARITHMETIC PD> population / land = ARITH PD PHYSIOLOGICAL> 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. o 1o 2o 3o 4-
