Question

This map shows global variations in the fertility rate in 2014. The legend gives the number of children born per woman that year. If the trend continues, how will the likely effect on the food and water supply in region 1 compare with the likely effect in region 2?

Answer 1

Explanation:

Life expectancy is the key metric for assessing population health. Broader than the narrow metric of the infant and child mortality, which focus solely at mortality at a young age, life expectancy captures the mortality along the entire life course. It tells us the average age of death in a population.

Estimates suggest that in a pre-modern, poor world, life expectancy was around 30 years in all regions of the world.

Life expectancy has increased rapidly since the Age of Enlightenment. In the early 19th century, life expectancy started to increase in the early industrialized countries while it stayed low in the rest of the world. This led to a very high inequality in how health was distributed across the world. Good health in the rich countries and persistently bad health in those countries that remained poor. Over the last decades this global inequality decreased. No country in the world has a lower life expectancy than the countries with the highest life expectancy in 1800. Many countries that not long ago were suffering from bad health are catching up rapidly.

Answer 2

Answer:

Life expectancy: It is the most important indicator of population health. Life expectancy is a broader statistic than infant and child mortality, which focuses primarily on death at a young age since it measures mortality over the whole life cycle. It provides the average death age of a population.

Explanation:

Step 1: In the pre-modern, impoverished world, life expectancy was around 30 years, according to estimates.

Step 2:

• Since the Age of Enlightenment, life expectancy has climbed considerably. Early in the nineteenth century, life expectancy began to rise in the first industrialized nations while remaining low in the rest of the globe.
• This resulted in a very unequal distribution of health throughout the globe. Good health in the wealthy nations and continuously low health in the remaining impoverished nations.
• This worldwide inequity has diminished during the last decades. No nation has a shorter life expectancy than the nations that had the greatest life expectancy in 1800.
• Many nations that suffered from poor health not so long ago are catching up quickly.
