Population Studies: Defining Our Terms

1. Life Expectancy- is the expected (in the statistical sense) number of years of life remaining at a given age
2. Crude Birthrate-  is the nativity or childbirths per 1,000 people per year (in estimation review points)
3. Crude Death Rate- the total number of deaths per year per 1000 people
4. Rate of Natural Increase is the crude birthrate minus the crude deathrate of a population
5. Total Fertality Rate- of a population is the average number of children that would be born to a woman over her lifetime
6. Net Migration Rate- is the difference of immigrants and emigrants of an area in a period of time
7. Population Pyramid is a graphical illustration that shows the distribution of various age groups in a human population
