(US Census Bureau) This rapid growth in population means little to most people living in this today’s world but it’s a phenomenon that should be a concern to all. It took from the start of human history to the industrial revolution around 1945 for the population to grow to 2 billion. If we then look at the figures after 1945 then we would realize

suggests that demographic dynamics is the change in population in terms of size composition‚ age structure‚ and urbanization. This includes the causes and consequences of migration‚ fertility and mortality. These dynamics are different from the past since each and every country experiences changes in terms of living condition‚ number of people born and people who died in that particular time. This essay will discuss the current size of the population‚ how does it effect the economic development‚ the

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

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
