What is demography?
In short, demography is a statistical study of human.
Population analysis can be applied to a society or a particular group of people, based on criteria such as education, nationality, religion, and ethnicity.
Demography is generally regarded as a field of sociology.

Population studies also cover research on changes in population, such as population size, distribution and configuration, birth, death, migration and social mobility.
The central focus on demography is to establish a reliable to measure the overall population count, birth rate, marriage and mortality.
these measurements today have a very big problem.
The records of birth and death, the most reliable data, are traced back to 200 years ago.
Even if data Most of exists, there is a variation in the subject matter, and the recording process is difficult to interpret.
Evaluation of demographic trends requires reliable and long-term data.

#My opinion
I found a lot of questions about demographic statistics this time.
Many incidents of accidents, such as war and infections, often happen around the world.
The number of deaths from this war or illness tells people about newspapers and TV.
How do you measure measurement?
And is that number accurate?
We also believe that we live in a relatively safe era compared to the past.
With the advancement of medical technology, the average life expectancy has also risen greatly.
I think that demographics will play an important role in controlling and manipulating these large numbers of people.
I agree with your opinion.
ReplyDeleteThere are many problems in measuring the total population.
Therefore, it is important to use reliable figures.
It was interesting to explain why population measurement is difficult.
Demographic statistics is useful.
ReplyDeleteBut it is not accurate.
So, when we use those data, we could do with being careful.
I do not have an accurate knowledge of how to measure the number of deaths caused by war or illness.
ReplyDeleteHowever, I think that the number of dead bodies detected in the case of war will be measured, and that deaths due to illness will be measured using hospital records.
Since the press has to deliver accurate information, the numbers mentioned in the newspaper or TV are expected to be accurate.
