Document Summary
Chapter 10 applying population ecology: the human population. Demography- the study of size, composition, and distribution of human populations and the causes and consequences of changes in these characteristics. Crude birth rate (br)- the number of live births per 1,000 people in a population in a given year. Crude death rate (dr)- the number of deaths per 1,000 people in a population in a given year. Doubling times- a measure of population growth which is the time (usually in years) it takes for a population growing at a specified rate to double its size. Rule of 70- a quick way to calculate doubling time: 70/percentage growth rate = doubling time in years (ex. If the population grew by 1. 2% you would go 70/1. 2 to get 58 years double time) Fertility- the number of births that occur to an individual woman or in a population. Two types of fertility rates affect the country"s population size and growth rate:
