Question

According to the presentation by Hans Rosling and Gap Minder, why should we "not panic" about the world's population? In other words, what are the current trends in global population (how many, who, where, etc) and what should we anticipated for the future? According to the presentation, why is this potentially better than most people envision? In your discussion include enough specific detail (examples, statistics, etc) to highlight your understanding of the data on population trends and demography.

Answer 1

According to Hans Rosling and Gapminder presentation,In developed countries a ratio near 2 parents to 2 children most exist and developing nation getting closer.As a result a equalising health outcomes,low child morality and family planning , family sizes go down and population growth slows in a predictable way.

Population is a dynamic field.There have been significant change s in birth rate and the population projections of countries and continent s in recent years.Global population is still growing by more than 80 million a year.

World population is around 7,771,825,400.China is the most populated country with 1,439,323,700.showing map of population growth rate.

Projections has usually assumed that fertility rates will have declined by 2020 and the population will be stable or will decrease.

Envision:-present growth rate has slowed .The excess almost all be in the developing world where the young largely outcomes the old.If population growth were to continue beyond 2050 one can't be other than exceeding glooming above the prospects.

Population tends and demography :-Around the world population are aging.This is relatively new demographic phenomenon because most of human history population were young and lives were short.two demographic trends.People today are living longer than before aging is declining in birth rate with lower birth rate younger generation are smaller related to older generation.Thus raising the average age of the population.examples for demographic trends are population,age,gender,caste etc
