These include the United States, Indonesia, Brazil, Pakistan, Nigeria, Bangladesh, Russia, Mexico, Japan, Ethiopia, and the Philippines.

The 80’s brought a slight stagnant rise in the population growth rate, but in the 1990’s, the rate of population growth dropped down to less than 1.5% and has been declining throughout the 2000’s. For instance, the United States includes race as self-identified data that reflects a social definition rather than a biological or anthropological one. Office for National Statistics research work on a simple method for producing population estimates by ethnic group and religion. We predict the world to be around 30% more populated by 2050 because of better healthcare allowing longer life expectancy and lower infant mortality rates. The rate of population growth was highest in 1970, around 2% growth per year, before declining in 1980.

Here's an interesting perspective on today's world population in 2016: today's world population (~7 billion) is approximately 6% of the estimated 110 billion who have ever lived. Global life expectancy has also improved in recent years, increasing the overall population life expectancy at birth to just over 70 years of age.

Others, including the US Census Bureau and World Bank, believe that the total population of the world reached 7 billion in 2012, around March or April. Annual estimates are for mid-2011 to mid-2016. The 20th century, however, is where population growth really took off, and over the past 100 years, the planet's population has more than tripled in size. Some believe that gradual increases in living standards will result in similar patterns to those in Western Europe, where birth rates are declining rapidly. This is because India’s population will grow, while China is projected to see a loss in population. Here's a timeline of the world population growth milestones: Most people agree that population increases will continue, but there are arguments about the rate of increase, and even a few people who believe population decreases are likely. Meanwhile, other countries may use different measures of ethnic groups, such as English, German, East Indian, etc. A few scientists even believe that populations will decrease. A handy guide to let you know where to find local statistics. Breaking down the global population by race is difficult primarily because of the meaning of the word “race.” Race is considered as a construct defined by society based on certain biological features that society has deemed to be significant.

Every five years since the 1970s, the population growth rate has continued to fall. According to World Population Prospects, the global population in 2050 will be around 9.77 billion people, which is 2 billion more than what the current population is today.

What will the world look like in 2050?

In 2040, this number will grow to more than 9 billion. In 2018, the world’s population growth rate was 1.12%. Particularly of interest, India is on track to overtake China's position as the most populous country by the year 2030. The projected global life expectancy is only expected to continue to improve - reaching nearly 77 years of age by the year 2050.
Of these nations, all are expected to continue to grow except Russia and Japan, which will see their populations drop by 2030 before falling again significantly by 2050.
