Developed and Developing Countries
According to the Human Development Index , there are 35 countries that are "highly developed“ in the world. The total population of these developed countries is 14.6% of world population. This means that 85.4% of the world's population lives in developing countries. [1]

4. World Population Growth
The world population had double in half of a century from about 3 billion in 1950s to 6 billions in Since then, world population has increasing by 1 billion people every years. Current projections show the increase in population to reach 9.2 billion by 2050, and 12 billion by [2]

Roughly 9 in 10 children (1.6 billion total children) under the age of 15 currently reside in developing parts of the world.

8. Developed vs Developing Countries
Population Growth
Developed vs Developing Countries
The majority of the growth is occurring in developing countries, most of which is occurring in poor urban areas. The population growth in developing countries will be almost 20 times that of developed countries by 2050.

Population Increase Developing Nations
Increase in Growth is due to:
Longer life expectancy
Fertility rate remains high in developing nations
Poverty
Limited access to health care, contraception, and education
Social, cultural, and lack of women’s rights
Region like sub-Sahara Africa, Middle East, and Southeast Asia lack major access to family planning services. [5]

For a population to replace itself, the fertility rate have to be 2.1 children per woman.

13. Population Growth
World Population Growth Rate by Percentage
Although world population growth rate is declining, population growth will continue to increase because nearly 1/3 of the world’s population is under 15 years of age and therefore has not yet reached childbearing age. Since this demographic group is so large in absolute numbers, even if each woman has fewer children than in the past, there will still be a significant increase in global population over the next several decades. [7]

14. Between 2011 and 2100 Population Growth
Future Growth in Developed and Developing Countries
Between 2011 and 2100
High-fertility countries –
Most of sub-Sahara Africa- population is projected to triple
Going from 1.2 billion to 4.2 billion
This projection assumed that a wider availability of family planning will continue to be implemented. If high fertility countries do not achieve this reduction- those population may increase by 4 to 5 fold.
Intermediate-fertility countries –
US, Mexico, India- will increase by 26%
Low-fertility countries –
Most of Europe, China, and Australia, Japan, will decline by about 20%[8]

Developed Countries – U.S.
The U.S. population’s current growth rate is 1.1% per year making it the fastest-growing industrialized country in the world. It will be more than half a billion (520 million) people within the next 40 years (2050). The main population growth is coming from immigrations and lower income families.[9]

17. U.S. Population Growth vs Resources
Although the U.S. population is only 4% of the world total population, it consumes 25% of the total resources, as well as producing more carbon dioxide and waste per capita than any other nations. Any population changes in the U.S. have a powerful impact in global resources. [10]

U.S. Population Growth
If U.S. Population Keep Increase…
For every 1 person that is added to the US population, 1 acre of land is lost due to urbanization and highway construction alone.
Food prices will increase 3 to 5 time the current price. Right now, about 15% of US income is spent on food compare to 50%-60% in developing countries. That 15% is expected to increase to 40% to 50% by 2050.
Only 0.6 acres of farmland will be available per person, as oppose to 1.2 acres per person to maintain the current US diet.
The US will cease from exporting food by 2025 to support domestic needs.
Since food exports earn $40 billion for the US annually, this will result in even greater trade deficit.
With the US being the world's largest food exporter, the survival of millions of people around the world will be in question.
Current available resources (land, water, energy) will be exhausted within the next years. [11]

19. Population Growth vs Resources
The rate of population growth has a strong correlation with the effectiveness of the dominant fuel source at any given point in history. As the chart below shows, wood was the dominant fuel until coal came on the scene in the 1600s. The population growth rate increased modestly with the proliferation of coal. But the real exponential growth began with the discovery and exploitation of crude oil. Crude oil production is peaking and the world is in the early stages of a transition from fossil fuels to renewable sources of energy. [12]
Figure 1.13

20. Population Growth vs Resources
Much of what we consume is not renewable. As our population increases, we are exponentially bumping up against the limits of earth’s ability to provide for us.
According to the Millennium Assessment, 60 percent of earth's ecosystems are currently being used at a rate exceeding their capacity to provide goods and services. [12]
Figure 1.14

21. Population Growth vs Resources
China, Brazil, and India’s energy consumption is growing quickly as they move toward American patterns of consumption. The trend is strong and steady, with no signs of slowing down.[13]

22. Population Growth
More Food Yet More Hunger – Green Revolution
Increase in food production does not end hunger. If the poor don't have the money to buy or get access food, increase in production is not going to help them.
From : The total food available per person in the world rose by 11 percent over those two decades, while the estimated number of hungry people fell from 942 million to 786 million, a 16 percent drop.
However, if you eliminate China from the analysis, the number of hungry people in the rest of the world actually increased by more than 11 percent, from 536 to 597 million. In South America, for example, while per capita food supplies rose almost 8 percent, the number of hungry people also went up, by 19 percent.
In south Asia, there was 9 percent more food per
person by 1990, but there were also 9 percent
more hungry people. Nor was it increased
population that made for more hungry people.
The total food available per person actually
increased. What made greater number of
people in hunger was the failure to address
unequal access to food and food-producing resources.[13]

23. Population Growth
Conclusion
Population growth must stop!
Developing Countries:
Reduce in resource consumption
Implement family planning, contraceptives, and education
Equal access to food and water
Population growth decreases as hunger and poverty decrease
Developed Countries:
US must control population growth
Reduction in resources consumption and population control must occur simultaneously if we ever expect to make it.
