What are the reason for increasing population day by day ? And what are the measures to control this problem?
Answers
Answer:
The population of the world, now somewhat in excess of three billion persons, is growing at about two per cent a year, or faster than at any other period in man’s history. While there has been a steady increase of population growth during the past two or three centuries, it has been especially rapid during the past 20 years. To appreciate the pace of population growth we should recall that world population doubled in about 1,700 years from the time of Christ until the middle of the 17th century; it doubled again in about 200 years, doubled again in less than 100, and, if the current rate of population increase were to remain constant, would double every 35 years. Moreover, this rate is still increasing.
To be sure, the rate of increase cannot continue to grow much further. Even if the death rate were to fall to zero, at the present level of human reproduction the growth rate would not be much in excess of three and one-half per cent per year, and the time required for world population to double would not fall much below 20 years.
Although the current two per cent a year does not sound like an extraordinary rate of increase, a few simple calculations demonstrate that such a rate of increase in human population could not possibly continue for more than a few hundred years. Had this rate existed from the time of Christ to now, the world population would have increased in this period by a factor of about 7×1016; in other words, there would be about 20 million individuals in place of The rates of population growth are not the same, of course, in all parts of the world. Among the industrialized countries, Japan and most of the countries of Europe are now growing relatively slowly—doubling their populations in 50 to 100 years. Another group of industrialized countries—the United States, the Soviet Union, Australia, New Zealand, Canada, and Argentina—are doubling their populations in 30 to 40 years, approximately the world average. The pre-industrial, low-income, and less-developed areas of the world, with two thirds of the world’s population—including Asia (except Japan and the Asiatic part of the Soviet Union), the southwestern Pacific islands (principally the Philippines and Indonesia), Africa (with the exception of European minorities), the Caribbean Islands, and Latin America (with the exception of Argentina and Uruguay)—are growing at rates ranging from moderate to very fast. Annual growth rates in all these areas range from one and one-half to three and one-half per cent, doubling in 20 to 40 years.
The rates of population growth of the various countries of the world are, with few exceptions, simply the differences between their birth rates and death rates. International migration is a negligible factor in rates of growth today. Thus, one can understand the varying rates of population growth of different parts of the world by understanding what underlies their respective birth and death rates.

For a country to develop it should have a positive growth rate.
- But if the rate of growth is too high then it will cause a major problem for the country.
- With increasing population there will be less opportunity to everyone, creating chaos, food, money and day to day life commodities will not be distributed evenly among people. The economy will degrade.
- It happens mainly due to social ideology that prevails at a particular period. For example, in India, there was a spurt in the rate of growth of the population from the 1970s to the 1990s.
- Most of the people were illiterate and did not know about family planning. Many families had a minimum of 10 children at that time.
It is very important to control the birth rate otherwise country's progress would slow down to a great extent.
- There is no particular way to decrease the birth rate particularly in a democracy it is very difficult. It all depends on society level education on family planning.
- It is not something that develops in a year but takes time. Literacy is the only way possible so that individually, one can make decisions.
