INPUT VARIABLES (CONTINUED):

Initial Fertility: Average number of births per woman over her lifetime at the start of the simulation.
Fertility Change: If this is set to "On" the fertility changes from the value set by "Initial Fertility" to the level set by "Final Fertility" over the time period set by "Development Time". If this is set to "Off" the fertility remains at the level set by "Initial Fertility".
Final Fertility: If "Fertility Change" is on, the fertility changes to this value during the time set by "Development Time".
Development Time: Controls the time period over which the fertility rate (if "Fertility Change" is set to "On") and the level of economic development (if "Economic Dev." is set to "Increasing") change.
