The world’s population continues to grow. There now are about 4 billion of us on earth. That could reach 6 billion by the end of the century and 11 billion in a further 75 years. Experts have long been concerned about such a growth. Where will we find the food, water, jobs, houses, school and health care for all these people?

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.

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 pregnancy. 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 grow.

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 half since 1970.

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.

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.

The advantages and disadvantages of a large population have long been a subject of discussion among economists. It has been argued that the supply of good land is limited. To feed a large population, poor land must be cultivated and the good land worked intensively. Thus, each person produces less and this means a lower average income than could be obtained with a smaller population. Other economists have argued that a large population gives more chance of development of facilities such as ports, roads and railways, which are not likely to be built unless there is a big demand.

One of the difficulties in carrying out a worldwide birth control program lies in the fact that of ficial attitudes to population growth vary from country to country depending on the level of industrial development and the availability of food and raw materials. In the developing country where a vastly expanded population is pressing hard upon the limits of food, space and natural resources, the first concern of government will be to set a limit on the birthrate, whatever the final result may be. In a highly industrialized society the problem may be more complex. A decreasing birth rate may lead to unemployment because it results in a declining market for manufactured goods.

When the pressure of population on housing declines, prices also decline and building industry grow weaker. Faced with concern such as these, the government of a developed country may well prefer to see a slowly increasing population, rather than one which is stable or in decline.
