How many people are in the world?
How many of us ever think of that “how many people are in the world” because we all are a part of this world? The UN standard estimation holds down the total population of the world to be around 7700 million, prioritized approximation as done recently on December, 2018. The “World Population” denotes to the human population (the total number of humans currently living) of the world. The population of the world is rapidly increasing day by day.
How Many People Live In The World?
The world’s population today is approximately 7.7 billion. The minimum age average mean is around 30.1 years taking in the mean of the ages of the old and the young. Around 1.8 Billion of the people living on earth are just teenagers, specifically saying they are just 15 years of age (give or take 1 or 2 years). People somewhere in the range of 15 and 64 years of age make up 65.9% of the population, and another 7.9% are 65 or more. Life expectancy of people as calculated by statistics is around 70.5 years. This is actually a statistical average done between life expectancy of men being around 73 years, whereas for women it is around 68 years. Shrewd! The global fertility rate is around 2.52 children per woman.
History of Population Growth on earth as mentioned.
On earth, the population growth is basically a reason for its incredible habitable environment (that is what biology states). On a discovery for a better source of food for the humanity which was done by the technique of Agriculture, human population saw a rise in the number. Right now ever, the world’s population was somewhere between 1 and 15 million. Around half a hundred million of people occupied the population on earth, which was during the time of the Roman empire alone itself. As the world’s population kept on growing, illnesses plagued and wiped out huge amounts of people. For instance, between the years 500 and 800 AD, the Justinian Plague killed roughly half of the European population. During the time of the middle ages around 14the century, the population was numbered around half a billion, as recovery from diseases became easy and practices were productive. However, the Black Plague took around 100 million lives in the year 1400 AD. Two centuries had gone before the population recovered from its losses of the Black Plague.
The population saw its tuned rise to 1 billion, when it happened for the first time in the 1800s. Quite a leap. From that point forward, however, population growth accelerated very quickly.
The Most Populated Countries and Cities
The continental of Asia is home to 60% of the world’s population and hosts the top 2 most populated nations in the world, China and India. Together, these two countries hold 37% of the world’s population. To know that “how many people are in the world” or “How Many People Live in The World”, it is an important to understand that the most populated countries and cities in the world.
- China has a population of over 1.38 billion. The birth rate in China is actually over the top of around 1200 births for 1000 people, a 20% more increase on population density. Meanwhile, the death rate became significantly low which was less than 1% (7 deaths per 1000 people). The life expectancy in the country is 75.35 years. Around 73.4% of the population is between 15 and 64 years old. The fertility rate is 1.55 children per woman.
- India has a population of over 1.33 billion. This number represents 18% of the world’s population. Mumbai is regarded as one of the most densely populated in india (in the world too by some margin due to better facilities). Delhi is the second most populated and has a population of 11.5 million. In india, the birth rate is just 2% of 1000 people and the death rate is just below 1% (to be exact, 7). The life expectancy in this country is 68.89 years of age. Around 63.6% of the population is between 15 and 64 years of age. The fertility rate is 2.3 children per woman.

How to stop population growth
To start with, we have to educate people about the birth controls & other measures, they have to know that if the population keep of rising then who devastating it could be for the entire society. We need to enlighten them concerning 2 child policy. Children for every family is expected better to be around maximum of 2 and keeping it below the level always helps as much as possible because then only we can grow fast & the poverty rate will also decrease & with it you should also be familiar with that “how many people are in the world” right now. Increasing in population is also increasing the poverty because the way of earning is limited and more. People opt out for a single physical job and the employment oppurtunities get around for hundreds of peole which just 1% chance for any body out of hundred. Those out there who need job will suffer but if you have less population then this crisis will not happen & everyone will have at least one source of income.
