Populations Population Dynamics: Factors Affecting Population Size Population change 2 ways populations increase births immigrations 2 ways populations decrease deaths emigrations Equation for calculating population change Calculate Population Change 1. Use the data below to calculate population change Births = 202,667 Deaths = 198, 590 Immigrations = 57,033 Emigrations = 37, 291 2. Use the data below to calculate population change Births = 355,077 Deaths = 109,855 Immigrations = 57,563 Emigrations = 7,595 3. 4. Growth rate = 5. Change in number of individuals 6. Time period Exponential Growth Population doubles every generation 2 assumptions 1) increasing birth rate 2) decreasing death rate In nature, obstacles to exponential growth Limits on Population Growth There is no indefinite population growth no real population can grow at its intrinsic rate of increase because there are limiting factors
