Test Day Part 2 and Unit 2

Today in Human Geo, we resumed our test after the fire drill on Friday limited our time. I felt that the test was fair since all questions were covered in class. After the test, we went over definitions and explanations on important words to know in Unit 2. These words are life expectancy, crude birth rate, crude death rate, developing nations, developed nations, rate of national increase, net immigration rate, immigration,  emigration, push force, pull force and total fertility rate. The only four definitions that we went over is life expectancy, crude birth rate, crude death rate and rate of national increase. Life expectancy means average number of years to be lived by a group born in the same years. Crude birth rate is number of births per 1000 of population. Crude death rate is number of deaths per 100 of population. Finally, rate of national increase is (birth rate-death rate) / 10. We also went over the first four important facts that have to do with population. There is currently 7 billion people on Earth and about 77 million per year. Also 90% of population growth is from Africa, South and East Asia and Latin America. The last fact is that women lives longer than men due to the fact that men take a riskier way of life.
