Human Population Dynamics

3. A conceptual formula used to estimate human impact on the environment.
8. The number of deaths of children under one year of age per 1,000 live births.
9. A model that describes how countries move from high birth/death rates to low birth/death rates as they industrialize
10. The required to offset the average number of deaths in a population to keep the population size stable
12. The number of deaths per 1,000 people in a population per year.
13. A measure of how much biologically productive land and water an individual or population requires to produce the resources it consumes and to absorb its waste.
14. The idea that human population grows exponentially while food supply grows linearly, leading to eventual "overshoot" and collapse.
15. The average number of children a woman will have during her childbearing years.
16. The shift from rural to city living, which usually correlates with lower fertility rates.

1. The maximum number of individuals of a species that an ecosystem can sustainably support without degrading the resource base.
2. A graphical illustration that shows the distribution of various age groups in a population, which helps predict future growth trends.
4. Factors that affect population growth based on its size (e.g., disease, food competition, waste buildup).
5. The number of live births per 1,000 people in a population per year.
6. The number of years it takes for a population to double in size.
7. Educational, social, and medical services that empower individuals to determine the number and spacing of their children.
11. Growth at a constant rate of increase per unit of time
