Population Growth components
- Fertility —–> Birth Rate
- Death Rate
Replacement Fertility
the total fertility rate—the average number of children born per woman—at which a population exactly replaces itself from one generation to the next, without migration.
-This rate is roughly 2.1 children per woman for most countries, although it may modestly vary with mortality rates
Family planing programs
- educational, comprehensive medical or social activities which enable individuals, including minors, to determine freely the number and spacing of their children and to select the means by which this may be achieved
Demographic transition
a model that describes population change over time
Demographic Dividend
growth in an economy that is the result of a change in the age structure of a country’s population.
The change in age structure is typically brought on by a decline in fertility and mortality rates
According to World Population Prospects (2019)
The SIZE, AGE STRUCTURE and DISTRIBUTION
Definition of Size:
According to World Population Prospects (2019)
Increased, continue to increase slowly through the end of the century.
Age structure:
According to World Population Prospects (2019)
Global population growing OLDER, but still young in some countries.
Distribution:
According to World Population Prospects (2019)
Regional population RE BALANCING:
Share of EU and North America declining
Sub-Saharan Africa gaining
Size (data) - population size
The world population was 7.7 billion in 2019
- increased by 2 billion in the past 25 years
- expected to increase by 2 B by 2050
- 1.2 B after 2050 (for 50 years)
Size (data) - rate growth
population growth rate slowed to 1.1% from 2.1%(1965-1970 peak)
- expected to slow through the end of the century
Age structure (data)
- population is growing older due to increasing life expectancy and declining fertility levels
- In 2018, for the first time in history, global population 65+ outnumber children under five
