Explanation

In 2017 the UN predicted a decline of global population growth rate from +1.0% in 2020 to +0.5% in 2050 and to +0.1% in 2100.

If the world’s population continues at its current rate of growth, approximately how long would it take to double in 64 years

Explanation

 The current average population increase is estimated at 81 million people per year.

Explanation

The dependency ratio is the ratio of the young and old to working-aged people

انحصار کا تناسب نوجوان اور بوڑھے کے درمیان کام کرنے والے عمر کے لوگوں کا تناسب ہے۔

Explanation

Explanation

Equation for Rate of Natural Increase (RNI)

(Birthrate/1,000) – (Death Rate/1000) = (BR-DR)/1000 = RNI %

Explanation

Both the crude birthrate (CBR) and the crude death rate (CDR)

the number of births or deaths which occur in a given year per 1000 population

Explanation

List of Demographic Transition all five Model Stages

Stage 1: High Population Growth Potential.

This is a state of high birth and death rates culminating in low population growth overall.

Stage 2: Population Explosion.

With a consistently high birth rate and decreasing death rate, population grows rapidly.

Stage 3: Population Growth Starts to Level Off.

                As the birth rate falls and the death rate remains low, the population continues to increase. LIKE CHINA

Stage 4: Stationary Population.

                Traditionally considered to be the final stage, this is one of demographic stabilization, in which both birth and death rates are low. This means that the overall population stays fairly low.

Stage 5: Further Changes in Birth Rates.

This final, contested stage may predict higher or lower fertility levels depending on which theorist you ask.

Explanation

The annual number of live births per 1,000 people is called the Crude Birth rate

ہر ایک ہزار افراد کی سالانہ پیدائش کی شرح کو خام پیدائش کی شرح کہا جاتا ہے۔

the annual number of deaths per 1,000 people is called the Crude death rate

ہر ایک ہزار افراد کی سالانہ اموات کو خام اموات کی شرح کہا جاتا ہے۔
