Total Fertility Rate(TFR shows the average number of children born to a woman during her lifetime (woman aged 15-49.) What are the different measures of mortality? 1. Crude death rate, 2. age-specific death rate, 3. expectation of life at birth (life expectancy), 4. infant mortality rate What is the best single measure of mortality/health levels in a population? Life table (life expectancy) What does the term net-migration refer to? Net migration = immigration-emigration What does the rate of natural increase measure? Natural increase= birth-death -measuring the population change excluding the effects of migration What is the difference between the rate of growth and the rate of natural increase? -The rate of growth is a measure of total population growth including the influence of migration-the rate of natural increase does not include migration.
