The world at 7 billionhttp://www.youtube.com/prbnet

• Increasing World population trend –

6 billion in 1999 to 7 billion in 2011.

• 6th and 7th billion were each added in record time—only 12 years.

• World Population projected to reach 9 billion by 2050

• Most population growth is concentrated in the world's poorest countries within the poorest regions.

Demographic Transitions

the shifts in birth and death rates

the transition took place differently in the developed countries

and developing countries.

The transition describes two trends:

the decline in birth rates, and the

decline in death rates as public health initiatives and

modern medicine increased life expectancy.

Strategies needed to Stop short of 9 Billion

What steps can be taken now to check the rapidly growing world population?The steps can be grouped into three categories—1. Rights- more than 40% of pregnancies worldwide are

unintended. There is a significant correlation between lower rates of childbearing and a higher presence of gender equality in the society.

2. Education-On average, educated women have fewer children.

3. Policy-Policymakers, while maintaining human rights, should frame policies that make people realize the costs of an increasing population.

1) Which of the two countries, India or China adds more people to its population annually? Calculate numbers added by applying the rate of natural increase to the population of the country.

2) What proportion of the world's people live in Africa, Asia, North America, Latin America, Europe and Oceania? Draw a bar chart showing the regional distributions of the world's population for this year, 2025 and 2050.

3) Choose four countries whose populations are growing at a 1.0 percent rate of natural increase or less.

4) Study the Demographic Transition Model. Why do Countries in Stage 1 have little to no population growth? Stage 2, has high birth rates and falling death rates, leading to population growth. What cause’s a country’s death rate to decrease?

Your turn now- Assignment 1

Use the 2011_population_data_sheet to answer the questions. 2011population-data-sheet

Assignment 2- support your answers with statistical data & graphs

1) Research and explain the relationship between women’s education level and fertility rates. Why is women’s education important in controlling the birth rate in developing countries?

2) World Hunger is on the rise. Hunger in a world of plenty? According to you what are the reasons for this growing problem. What are the ways in which the world can combat this challenge?

3) What do think we could do as a global society to help slow population growth in developing countries?

4) Why is gender equality important to control rapid population growth?
