World Population and Growth

There are approximately 7,266,153,848 inhabitants on the planet Earth to date. The world’s population fluctuates around that number every second of the day due fatalities as well as infant births. Currently, world population is growing at a rate of 1.14% per year. And the average population change is estimated at 80 million per year. World population growth rate has already reached its’ peak in the 1960’s when it was at 2% and above. The annual growth rate of world population is currently declining and is seen to further decline in the coming years. It is currently estimated that annual growth rate will be less than 1% by 2020 and cut in half at 0.5% by 2050.

Asia continues to top population growth by region, with China and India accounting for more than half of Asia’s total population. Asia also houses 60% of the entire global population. Total fertility rate is one indicator which measures annual population growth of a country. China has a low fertility rate per woman (1.6) due to its strict “one-child” policy, but the relaxing of the “one-child policy makes it difficult to predict. In India the total fertility rate has fallen from 5.5 in 1970, to 2.4 at present time. India is also projected to pass China in population size in 15 years, making it the world’s most populous country.

By the year 2050, Africa  is projected to increase in population to 2.4 billion from 1.1 billion today, making it the region with the largest population growth. Latin America/South America has a significantly lower birth rate, especially in countries like Brazil and Mexico, meaning this region has slow population growth. The region’s population is projected to increase from 618 million today to 773 million in 2050. North America has a rather low total fertility rate (Canada at 1.6 and the United States at 1.9). In Europe, its’ population of 740 million is projected to decrease to 726 million by 2050. This is due to women in Europe averaging only 1.6 children compared to 2.3 in 1970. The low fertility rate in the region has also created unprecedented aging- only 16% of the population is below the age 15. In the Oceania region of Australia and New Zealand, it is expected to experience continued growth from higher birth rates and immigration. Australia’s population of 24 million is expected to increase to 36 million by 2050; New Zealand’s population will increase from 4.3 million to 5.5 million.
