Population characteristics: population characteristics population density birth and death rates growth rates age structure spatial and temporal variations of population characteristics is central to many environmental problems and their solutions. Population change global scale: population change change over time, on a global scale two factors birth rate (b) number of births per 1000 people per year . Death rate (d) number of deaths per 1000 people per year. Population change global scale growth rate (g) birth rate (b) minus death rate (d) g = b d. If g > 0, population increases if g < 0, population decreases. Population growth and resource consumption ecological footprint the area of land that would be necessary to produce the resources used, and assimilate the wastes produced by a given population. Challenges of varying age distribution the size and age distributions of a country"s population can pose significant challenges: what kinds of challenges do countries with large populations of elderly people face?
