Question

Which factor has had the least effect on the rate of growth of population of the world?

Answer 1

Answer:

fertility

Explanation:

Over the last half century, the global fertility rate has fallen sharply.14 In the 1950 to 1955 period, the average woman was expected to have about five children over the course of her lifetime. By 2010-2015, the global average was about 2.5 children per woman.15 According to the United Nations Population Division, worldwide fertility rates are expected to continue to drop in the decades to come, gradually moving toward 2.1 children per woman, which is traditionally viewed as the “replacement level” needed to maintain a stable population in countries with low mortality rates among the young.16

As a result of declining fertility rates, global population growth is slowing. Over the four decades from 1970 to 2010, the number of people on Earth grew nearly 90%. From 2010 to 2050, the world’s population is expected to rise 35%, from roughly 7 billion to more than 9 billion.

Among the world’s major religious groups, Muslims have the highest Total Fertility Rate as of 2010-2015, a global average of 3.1 children per woman. This is one of the main reasons why the Muslim population is expected to grow not only in absolute numbers but also in relative terms – as a percentage of all the people in the world – in the decades to come.
