Population Rates

Today in class, we discussed crude birth rate, crude death rate, immigration and emigration. Crude birth rate is the number of births per 1000 population, and crude death rate is the number of deaths per 1000 population. When you subtract the crude death rate from the crude birth rate, you get the rate of natural increase, or RNI, which is the annual natural growth rate of a nation in percentage form. Then we got into net migration rate, which is the difference between the number of people leaving a countermand the number of people coming in to that same country during a year. An excess of people coming into a nation is net immigration, written as a positive number. An excess of people leaving a nation is net emigration, written as a negative number. People have push forces and pull forces for immigrating and emigrating. Push forces include civil war, environmental degradation, unemployment/ underemployment, and religious of ethnic persecution. Pull forces include better economic o...

Population Pyramids

Today we discussed population pyramids, a way to measure population while taking aspects like age and gender into consideration. In a population pyramid, men are on the left, women are on the right, the youngest are on the bottom and the oldest are on the top. The ages are separated into 5-year increments and grouped into pre-reproductive (0-14), reproductive (15-44) and post-reproductive (45-100+). We can predict future population trends by looking at the base of the pyramid. A large base points toward population increase, and a small base points toward a population decrease. Pre-industrialized countries tend to have larger populations because of the lack of availability of birth control, while developed countries tend to have steady population numbers or population decrease as people put off having children for later years or simply never have children. Pre-industrialized countries also usually don't have highways, great schools, or airports. This is because most of the state...

Life Expectancy

In class, we discussed life expectancy in different nations. We learnt that Monaco, a very wealthy island, has the highest life expectancy in the world. This is probably due to rich people being able to afford medicine and treatments for sickness, and are less prone to sickness in the first place because of their being able to afford clean conditions. The USA was around #45, which makes sense. Countries in war and with poor infrastructure, like Chad, were near the bottom. We also explored how women almost always have a higher life expectancy compared to men, which could be due to more men in the military, and more men doing dangerous jobs. This is most likely due to women getting turned down for more 'masculine' and therefore dangerous jobs, such as labor. Gender roles seem to take a role in this, because if men weren't taught that dangerous jobs were manly, and if women weren't taught that they were too fragile and weak to do anything dangerous, these numbers would pr...
