Population and Settlement Review

Today in class we reviewed for our upcoming test on population and settlement. I feel this review was helpful for preparing me. First thing to go over while studying is about the world population. The most important facts would be that the worlds current population is 7.6 billion people, the first billion was reached in 1804, and 90% of the population growth rate is from developing countries such as Africa, South and Central America, East Asia, and Latin America. The next slides most important fact is Crude Birth rate is the number of births per 1,000 of a population, the Crude Death rate is the number of deaths per 1,000 of a population, and the Rate of Natural Increase(RNI) is produced from subtracting the death rate from the birth rate. If there are more deaths than births, the RNI would be negative, if there are more births the RNI would be positive. The Net Migration Rate is the difference between people entering and exiting a country . Immigration is the number of people entering a country and emigration is the number of people exiting a country. Then we discussed Push Factors and Pull Factors. A push factor makes somebody want to leave a country and a pull factor is what brings a person to a country. To keep a countries population the same, there needs to be a birthrate if 2.1 children per woman. If this rate is lower, the population will drop. If this number is higher, the population will grow. The final topic was Gross Domestic Product(GDP). The GDP divided by the number of people gives the GDP per capita.
