人口與社會相互影響

The size of the human population, its concentration in particular places, and its pattern of growth are influenced by the physical setting and by many aspects of culture: economics, politics, technology, history, and religion. In response to economic concerns, national governments set very different policies—some to reduce population growth, some to increase it. Some religious groups also take a strong stand on population issues. Leaders of the Roman Catholic church, for example, have long campaigned against birth control, whereas, in recent years, religious leaders of other major faiths have endorsed the use of birth control to restrict family size.

社會體系受到人口的影響

In turn, social systems are influenced by population—its size, its rate of change, and its proportions of people with different characteristics (such as age, sex, and language). Great increase in the size of a population requires greater job specialization, new government

responsibilities, new kinds of institutions, and the need to marshal a more complex distribution of resources. Population patterns, particularly when they are changing, are also influential in changing social priorities. The greater the variety of subcultures, the more diverse the provisions that have to be made for them. As the size of a social group increases, so may its influence on society. The influence may be through markets (such as young people who, as a group, buy more athletic equipment), voting power (for example, old people are less likely to vote for school bond legislation), or recognition of need by social planners (for example, more mothers who work outside the home will require child-care programs).

三大概念： 社會地位、 階層權利、 政治權力

Social Status: If you view someone as a social superior, that person will be able to have power over you because you believe that person has a higher status than you do.

Class Power: This refers to people having unequal access to resources. If you have access to something that someone else needs, that can make you more powerful than the person in need. The person with the resource thus has bargaining power over the other.

Political Power: Political power can influence the hierarchical system of power because those who can influence what laws are passed and how they are applied can exercise power over others.

社會數字劃分的標準及其三大指標

The digital division of a society is usually measured in terms of citizen/population access to ICT. Among the indicators for measuring access are (1) telephone density (teledensity); (2) personal computer (PC) deployment and penetration; and (3) number of Internet users.

Teledensity is the ratio of population to telephones (traditionally defined as fixed or wired telephone lines). This indicator of the division must be redefined as to include cellular/mobile phone users since in a number of developing countries there are more mobile phones than wired phones.

Personal computer penetration and deployment has also been used to measure access, since it is the most common way of accessing the Internet. However, recently more and more ways of accessing the Internet have been devised.

The number of Internet users is also a way of looking at the digital division. Statistics show that only about 10% of the world’s population is online. Furthermore, most of these Internet users are in the developed Western countries: the US, Canada and Europe account for about 63% of the

world’s Internet users. The Asia-Pacific’s share is about 30%. Africa and the Middle East combined account for less than 2% of the universe of Internet users.
