GLOBAL PATTERN OF POPULATION
Growth Rates and Population 2
Average fertility rate globally in 2019 is 2.51 compared to 1970 were it was 4.92 Median age globally in 1970 was 22, 2019 is 29.9 Population in the world is currently growing at a rate of around 1.14% per year. Annual growth rate reached its peak in the late 1960s, when it was a t 2% and above. The rate of increase. Has therefore almost halved since its peak of 2.19%, which was reached in 1963. The annual growth rate is currently declining and is projected to continue to decline in the coming years. Currently, it is estimated that it will become less than 1% by 2020 and less than 0.5% by 2050. This means that world population will continue to grow in the 21st century, but at a slower rate compared to the recent past. World population has doubled (100%) increase) in 40 years from 1959 (3 billion) to 1999 (6 billion). It is now estimated that it will take a further 43 years to increase by another 50%, to become 9 billion by 2042. The population growth rate is the rate at which the number of individuals in a population increases in a given time period, expressed as a fraction of the initial population. (2.1 is the replacement value) Global rates of population growth in the past and present have been influenced by technological developments, such as the industrial revolution, changing societal values such as the use of contraception and the role of women, economic changes, such as the cost of living, the expansion of globalisation in newly industrialising countries and also the influence of urbanisation.
Writing
Global population is not evenly distributed Presently that Asia is the region of the world that has the greatest number of people, China, India and Pakistan Distortion in the map of Africa- Particular countries of Africa are also experiencing enormous population growth Asia will continue to have the greatest number of people; however, the rate of increase is declining. Africa is the continent that will continue to experience the greatest growth rate in population. Europe as a continent will continue to experience a decrease in population, which means their population growth rate is 2.1 (natural increase) you will be the same, if dip below 2.1 population will decline.
Comparison of Agricultural revolution to industrial
Population growth was steady between the agricultural revolution (roughly 11,000 years ago) and 4000 years ago. Over the past 200 years (industrial revolution) the global population has grown exponentially.
Growth Rates and Population
The speed in which the growth takes place is influenced by the growth rate. To understand the growth of the global world population it is necessary to consider the annual growth rate. Since the 1960s the annual growth rate has halved, and it will continue to decline in the coming years. Presently on a world scale it is 1.07%, this results in 82 million people per year. World population will continue to grow in the 21st century but at a much slower rate compared to the recent past. The latest world population projections indicate that world population will reach 10 billion persons in the year 2055 and 11 billion in the year 2088.
Population changes throughout history
The year 1 A.D. - Population is estimated to sit between 200 and 600 million, growth rates was 0.05% (Demographic transition model stage 1) 1800- The world population reached 1 billion, this was influenced by the growth of modern society linked to the industrial revolution. The area of greatest growth was in fact Europe. 1930- The second billion (took 130 years to reach) 1960- the third billion (took 30 years to reach) 1974- the fourth billion (took 15 years to reach) 1987- the fifth billion (took 13 years) 1999- the sixth billion (took 12 years) 2012- the seventh billion (took 13 years)
