Population
1. The world's population continues to grow. There now are about 5 billion of us on earth. The figure could reach 6 billion by the end of the century and 11 billion in another 75 years. Experts have long been concerned about such a growth. Where will we find the food, water, jobs, houses, schools and health care for all these people?
2. A major new study shows that the situation may be changing. A large and rapid drop in the world's birth rate has taken place during the past 10 years. Families generally are smaller now than they were a few years ago. It is happening in both developing and industrial nations.
3. Researchers said they found a number of reasons for this. More men and women are waiting longer to get married and are using birth control devices and methods to prevent or delay pregnancy①. More women are going to school or working at jobs away from home instead of having children. And more governments, especially in developing nations, now support family planning programs to reduce population growth.
4. China is one of the nations that have made great progress in reducing its population growth. China has already cut its rate of population growth by about one half since 1970.
5. Each Chinese family is now urged to have no more than one child. And the hope is to reach a zero population growth with the total number of births equaling the total number of deaths, by the year 2000.
6. Several nations in Europe already have fewer births than deaths. Experts said that these nations could face a serious shortage of workers in the future. And the persons who are working could face much higher taxes to help support the growing number of retired people.

Human Wants
Human wants seem endless. When a starving man gets a meal, he begins to think about an overcoat; when an executive gets a new sports car, visions of country clubs and pleasure beats dance into view.
The many wants of mankind might be regarded as making up several levels. When there is money enough to satisfy one level of wants, another level appears. The first and most basic level of wants involves food. Once this want is satisfied, a second level of wants appears clothing and some sort of shelter. By the end of World War II these wants were satisfied for a great majority of Americans. Then a third level appeared. It included such items as automobiles and new houses.
By 1957 or 1958 this third level of wants was fairly well satisfied. Then in the late 1950s a fourth level of wants appeared: the "life-enriching" level. While the other levels involve physical satisfaction－the feeding, comfort, safety, and transportation of the human body－this level stresses mental needs for recognition, achievement, and happiness. It includes a variety of goods and services, many of which could be called "luxury" items. Among them are vacation trips, the best medical and dental① care, and entertainment. Also included here are fancy foods and the latest styles in clothing.
On the fourth level, a greater percentage of consumer spending goes to services, while on the first three levels more is spent on goods. Will consumers raise their sights to a fifth level of wants as their income increases, or will they continue to demand luxuries and personal services on the fourth level?
