Question

name: binnajj moaizs period 5 ch 2·kı 2·pg 5 - 6 chapter 2 - key issue #2.2: why is population increasing? > natural increase in history - p.52 1. the worlds population began to grow slowly around 8,000 b.c.e. why? 2. fill in the chart with the data given on page 52 of your textbook. then calculate the \a total increase of\ by subtracting the \to\ from the \from\. lastly, to find the \% of increase\ by following the formula given below.

time frame	# of years	increase from (in billions)	increase to (in billions)	a total increase of	% of increase
1974 - 1987	13 years
1987 - 1999	12 years
1999 - 2011	12 years
2011 - 2022	11 years

% of increase formula population growth (pg) % of increase = \\(\frac{to - from}{from}\\) then divide by 100 (or move the decimal twice) note: your math teachers have taught this concept but the wording is as follows: % of increase = \\(\frac{actual - original}{original}\\) then ÷ by 100 3. define natural increase rate (nr) - (include the meaning of the term
atural\) 4. more than __ percent of the natural increase is ________ in ________ countries. lets include the stats for the % of the worlds population growth. asia, sub - saharan africa, latin america, north america, europe (including russia) 5. define doubling time. 6. at the current rate of 0.9 percent per year, world population would ________ in about years. meaning by the year ________ the world population would reach around __ billion. do you think this will actually happen? why or why not? 7. pause & reflect 2.2.1. which region other than sub - saharan africa appears to have the highest natural increase rate?

Explanation:

Step1: Answer question 1

Around 8,000 B.C.E., the world's population began to grow slowly due to the development of agriculture. Agriculture provided a more stable food - source, allowing for more reliable sustenance and supporting a larger population.

Step2: Fill in the table (example for 1974 - 1987)

Suppose the "increase from" is 4 billion and "increase to" is 5 billion.
A total increase of: $5 - 4=1$ billion.
% of increase: $\frac{5 - 4}{4}\times100 = 25\%$

Step3: Define Natural Increase Rate (NR)

The natural increase rate is the difference between the birth rate and the death rate in a population. The term "natural" implies that it does not take into account migration (immigration and emigration) factors. It represents the growth of a population due solely to the excess of births over deaths.

Step4: General knowledge about population growth regions

More than 80 percent of the natural increase is in developing countries. In terms of world's population growth percentages: Asia has a significant portion, sub - Saharan Africa has a high percentage, Latin America has a moderate percentage, North America has a relatively low percentage, and Europe (including Russia) has a low percentage.

Step5: Define doubling time

Doubling time is the number of years it takes for a population to double in size, assuming a constant rate of population growth.

Step6: Calculate doubling time and future population

The formula for doubling time $T_d=\frac{70}{r}$, where $r$ is the growth rate. Given $r = 0.9\%$, $T_d=\frac{70}{0.9}\approx78$ years. If the current population trends continue, by adding 78 years to the current year, we can estimate when the population would double. Whether it will actually happen depends on factors like changes in birth and death rates, resource availability, and policy changes.

Step7: Identify high - growth region

Among regions other than sub - Saharan Africa, South Asia often appears to have a relatively high natural increase rate due to high birth rates and improving survival rates.

Answer:

1. Due to the development of agriculture providing a stable food source.
2. (Fill in the table according to textbook data and calculations as shown in Step2)
3. The natural increase rate is the difference between the birth rate and the death rate, not accounting for migration. "Natural" means excluding migration factors.
4. 80; developing; (Percentages for regions: high for Asia and sub - Saharan Africa, moderate for Latin America, low for North America and Europe)
5. The number of years it takes for a population to double in size at a constant growth rate.
6. Double; 78; (Estimated year based on current year + 78); (Estimated doubled population); (Opinion on whether it will happen with reasons)
7. South Asia.
