1. SUMMARY
Demography is the study about how human
population changed over time by births, deaths, migration and so on. From old
time, expanding of population is important. Expanding of population lead to many
competitions such as competition for resources. Demography relies on large date
sets that are usually derived from censuses and statistics of registration that
include the number of birth, death, marriage and so on. But in many countries,
acquisition of reliable demographic data is very difficult because this can be
associated with taxation.
In
demography, fertility is the ability that female can produce progeny.
Replacement level is the number of children that have to bear to maintain the
existing population. Here are some factors for greater longevity.:
Race, Ability to delay gratification, Lager social networks, Job satisfaction. Today, the most of world population growth
occurred in less developed countries. Every year, growing of the world’s
population is about 80 million. The more foods exist, the more people born. If
world’s human population increased, many problems occurred. For example, there
are little surplus food, Child poverty, Increase of crime rata and so on.

Reason of low birthrate in Korea is financial difficult, I agree with you. In Korea, salaries do not rise but prices continue to rise. So I think it is a problem to raise children. It is the desire of parents to want to do well for their child. You will want to send the school and do everything you want. However, because of economic difficulties, it is difficult to satisfy all the needs. To solve this problem, I think it is necessary for the government to make efforts. In fact, this solution is the most primitive and the most difficult. It is the ideal way for the government to support the costs of childbearing and afterwards, but in reality it will take a lot of time for the law to be enacted and budgeted, and there may be more corruption in between. However, if this proposal is realized, people will not be afraid to give birth and I think that the birth rate will also increase.
