Answer 1

Hint:
Population growth or population change reflects the change in the number of residents of any area during a specific period. This change can also be negative as possible to be positive. It can be expressed in the context of the full number or as a percentage. Population change in any area is an important indicator of economic development, social uplift and the historical and cultural background of the region.

Complete answer:
The population of the Middle East region is increasing at a rate of 2 percent per year, sub-Sahara is the second largest rate in the world after Africa.

Population growth is an increase in the number of individuals. The amount of global human population growth is approximately 83 million annually or 1.1% per year. The world population has become 7.8 billion in 1800. In 2020 it is expected to go further, and the estimation has put a total population of 8.6 billion by 9.8 billion mid-2050 and 11.2 billion, up to 2100. Life level in many countries with rapid population increases, while life-level in many countries of population growth are of high level.

"Population growth rate" is the rate on which the number of a person grows in a certain time period, which is expressed as a fraction of the initial population. In particular, the population growth rate refers to the change in population in the time period, which is often expressed as a percentage of the number of individuals in the population at the beginning of that period.

Population growth rate varies by the world, with the highest growth rate in sub-Saharan Africa and the lowest in Europe. For example, from 1950 to 2010, sub-Saharan Africa increased by four times, about 186 million to 856 million. On the other hand, only 35% increase in Europe, increased from 54 in millions to 2010 in 2010 in 1950. As a result of these different population growth, sub-Saharan Africa has changed from 12.4% to 2010 to 2010 by the world population in 1950. While in Europe, there was a decline of 22% to 11% in the same time period.

Hence, the correct answer is option B.

Note:
In some countries the population is getting reduced, especially in Eastern Europe, mainly due to low breeding rate, high mortality and emigration. In Southern Africa, the number of deaths related to AIDS is slower due to higher. Some Western Europe countries may also decrease in population. Japan's population began to lower in 2005.
