1、summary

 Demography is the study of population dynamics, covering the size, structure, and distribution of populations and their changes due to births, deaths, migration, and aging. By analyzing demographic indicators, sociologists can explain many social phenomena, such as the effect of population growth in European countries on hostilities before World War I. The discipline originated in the 18th century and relies on census and registration statistics. Important indicators include birth rate, death rate and migration trend, and fertility is significantly influenced by education level and development level. Demography explains social structures and patterns through detailed analysis and data.

2、Interesting place

The interesting thing about demography is that it reveals the hidden factors behind social phenomena. For example, by analyzing birth and death rates, it is possible to predict future demographic changes and their impact on the economy and society. It can also help us understand how migration trends are changing the face of cities and countries. Demography also demonstrates the profound effects of education, economic development, and health on population structure, such as the fact that high levels of education usually lead to lower fertility rates. In addition, demographic data helps formulate policies to address real-world issues such as aging, labor shortages and urban planning, demonstrating the critical role of data in social development.

3、problem 

How can population policies reduce poverty and promote social equity?

1. Summary Scientific method is a method of acquiring knowledge, a systematic mode of thinking and a means of research, which is used to solve problems, explore laws and test theories. The key processes include observing phenomena, constructing hypotheses, planning experiments, collecting data, analyzing results, and summarizing conclusions. The scientific method focuses on proof and repeatability, using experiments and observations to test hypotheses during research, and adjusting or confirming theories based on data. 2. Mention of new, interesting The debate between postmodernism and modernism has been going on for a long time, and they have done a lot of research to carry out this debate. Although this problem has been solved with the efforts of scientists, it also shows that the development of anything is not static, and only continuous exploration can make better progress. 3.

  summarize The scientific method is not a single recipe. It requires intelligence, creativity and imagination. In this sense it is not a blind standard or procedure, but more a way of thinking that encourages us to remain open and critical, constantly challenging and validating existing theories.

About the points I learned 1. The scientific method is based on careful observation and rigorous skepticism. This means that scientists should not readily accept any ideas or assumptions, but should always question and think critically about observational data. 2.Scientific inquiry is not merely the pursuit of truth, but the process of shedding inhibited skepticism and establishing reliable beliefs.

 Summary: Social stratification is a multidimensional concept encompassing the impact of factors such as wealth, income, race, education, and occupation on individuals' social status. In modern Western societies, social stratification is typically divided into upper class, middle class, and lower class, with each class further subdivided into smaller categories. Social stratification is not only about quantitative inequalities but also involves beliefs and attitudes toward social status. Within complex social structures, there exist various stratification phenomena, with the most privileged individuals and families enjoying disproportionate access to income, power, and other social resources. Social mobility refers to the movement of individuals, social groups, or populations between or within layers of the stratification system. Open stratification systems allow for mobility between individuals, whereas closed systems have minimal mobility, with social status often remaining uncha
