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.
