1_What I learned with 14th week Wikipedia link.

#What is Demography.
 Demography is the study about dynamics of human population. A demographic analysis is a sophisticated tool that can explain many social phenomena. Thus, the sociologist should prioritize the demographic indicators for possible explanations.

#Demographic Indicators: Fertility & Fecundity.
 Demographers focus on specific indicators of change, the most important two of which are fertility(called also fecundity) and mortality.

-Fertility
 Fertility, in demography, refers to the ability of females to produce healthy offspring in abundance. Another important demographic concept relating to fertility is replacement level. Replacement level fertility refers to the number of children that a woman has to have to replace the existing population. Sub-replacement fertility is a fertility rate that is not sufficiently high to replace the existing population.
-Fecundity
 Fecundity is the potential reproductive capacity of a female.

Some of more common demographic, which are used in relation to fecundity and/or fertility include:
  • crude birth rate
  • general fertility rate
  • total fertility rate
  • gross reproduction rate
  • net reproduction rate

#Effects of Overpopulation

 Many supporters of population control argued that the famine was not the only problem for overpopulation. Critics point out the ultimate lack of energy resources as well as the importance of serious communicable diseases in dense populations and war over scarce resources.
 Many critics argue that if there is on other action, simply feeding the world's population will only aggravate the problem. Natural growth will continue to grow to unsustainable level, and it will lead to a direct epidemic of disease, deforestation.

2_ Mention & Question about this week study.

 I've never thought about population problem. However, this week link has become an opportunity to seriously think about population problem. In summary, I only deal with overpopulation, but there is the underpopulation in Korea. I think this problem is due to the poor welfare of our country. 

 Korea's companies often ask about the planning of marriage and planning about having children when women are interviewed for a job. This is because the idea of giving birth to a child is rife with damage to the company.

 I wonder classmates' opinion. What do you think about Korea's underpopulation?
