number of factors that can contribute to the growth of a population and these trends can be seen in a number of species. It is generally believed‚ from an ecological perspective‚ that populations will display either an exponential of logistic growth rate. If optimal environments are consistently maintained with no biotic or abiotic limiting factors (excess food‚ excess space availability‚ optimum climactic environment‚ no predation‚ etc) then a population will grow in an exponential direction.

POPULATION GROWTH AND CONTROL Population is considered to be an important asset for any country for growth rate of any country is greatly dependent on the people living in that country. But when it starts growing without any proper proportion then it becomes a menace for that part of part of the world. The whole world is caught in the trap of overpopulation .people all over the world are distributed like pollen or germinating seeds and they are growing in number as anything. There is an uneven

The current estimate of the worldwide human population at this moment is 7‚241‚862‚395. For every person who dies during the next three days‚ somewhere around the world a baby will be born who will‚ physically speaking‚ replace that death. With that being said there are 108 deaths per minutes‚ 155‚911 deaths per day and 56‚907‚606 per year. After all of those replacement births take place‚ 684‚000 additional births will occur. Every Minute of the day there are 267 births so that means every day

Consequences of Population Growth The effects of population growth on economic development differ between the developed and developing countries. In the developed countries‚ population growth has enhanced the growth of such economies because they are wealthy‚ have abundant capital and scarcity of labour. O n the contrary the consequences of rapid population growth on the development of LDCs are not the same. Most developing countries are poor‚ capital scarce and labour abundant; and therefore population growth

I. Introduction The Philippine population in the early 1990s continued to grow at a rapid‚ although somewhat reduced rate from that which had prevailed in the preceding decades. In 1990 the Philippine population was more than 66 million‚ up from 48 million in 1980. This figure represents an annual growth rate of 2.5 percent‚ down from 2.6 percent in 1980 and from more than 3 percent in the 1960s. Even at the lower growth rate‚ the Philippine population will increase to an estimated 77 million

1994‚ the population of Pakistan was estimated to be 126 million‚ making it the ninth most populous country in the world. Its land area‚ however‚ ranks thirty-second among nations. Thus Pakistan has about 2 percent of the world’s population living on less than 0.7 percent of the world’s land. The population growth rate is among the world’s highest‚ officially estimated at 3.1 percent per year‚ but privately thought to be closer to 3.3 percent per year by many planners involved in population programs

There are many factors of population growth but we can put them into five main categories; birth rates‚ death rates‚ emigration‚ immigration and technology. Technology plays an important part in the population growth around the world. With the new technologies in medicine alone‚ the average age of a person has gone up. Not only that‚ but certain medical issues such as appendicitis where people would just die from can now be cured through surgery. Children born with defects such as a hole in there

Why there is a need to increase population in Singapore? As‚ we all know‚ Singapore is becoming an ageing population soon. So‚ a shrinking and ageing population means younger workforce‚ and a less vibrant and innovative economy. With slower business activity and employment opportunities‚ it will become more difficult to match the higher aspirations of a better educated and mobile Singaporean population. This may hollow out our population and workforce and worsen our ratio of younger to older
