• Population distribution


  One way to understand the distribution of people across the world is to reform the world map, not based on area but according to population
• Small countries with high population density

  • Bangladesh
  • Taiwan
  • Netherlands
• Large countries with small population

  • Canada
  • Mongolia
  • Australia
  • Russia
• Population density


  The number of people (population) divided by land area, measured in square kilometers (km²)
• Metro Manila is the world's most densely populated city (42,857 per sq. k)
• Bangladesh is the most densely-populated large country in the world, with 1,252 people per square kilometer
• South Korea is the second most densely-populated country at 528 people per square kilometer
• Population growth


  The increasing number of people living on our planet over the last 12,000 years
• The world population today is 1,860-times the size of what it was 12 millennia ago when the world population was around 4 million
• Around the year 1800 the world population was only around 1 billion people
• On average the population grew very slowly over this long time from 10,000 BCE to 1700 (by 0.04% annually)
• The world population was around 1 billion in the year 1800 and increased 7-fold since then
• Around 108 billion people have ever lived on our planet; today's population size makes up 6.5% of the total number of people ever born
• Two hundred years ago the world population was just over one billion. Since then the number of people on the planet grew more than 7-fold to 7.7 billion in 2019
• Most people always lived in Asia: Today it is 60% two hundred years ago it was 68%
• The world region that saw the fastest population growth over last two centuries was North America. The population grew 31-fold
• Latin America saw the second largest increase (28-fold)
• Over the same period the population Europe of increased 3-fold, in Africa 14-fold, and in Asia 6-fold
• Top five most populous countries


  • China (1.42 billion)
  • India (1.37 billion)
  • United States (329 million)
  • Indonesia (269 million)
  • Brazil (212 million)
• China has been the world's most populous country for several centuries, but it's expected that India will overtake China within the next decade
• Future population growth


  The annual population growth rate of the global population, which peaked around half a century ago and has been declining since then
• Peak population growth was reached in 1968 with an annual growth of 2.1%
• Since then the increase of the world population has slowed and today grows by just over 1% per year
• By the end of the century – when global population growth will have fallen to 0.1% according to the UN's projection
• Global migration


  A situation in which people go to live in foreign countries, especially in order to find work
• Most global migration is from developing countries to developed ones
• In 2017, over a billion people migrated: 244 million went abroad and 763 million moved within their home country
• United States is the top recipient of international migrants, having 49,777,00 in the year 2017
• In terms of migrant share in the total population, UAE's migrants are 88.4% of its total population
• Migrants tend to head to global cities. Dubai and Brussels have the highest number of foreign-born population at 83% and 62% respectively
• Sao Paulo in Brazil, Moscow in Russia and Cape Town in South Africa are all cited as cities with a growing international population
• In the Philippines: Naga and Davao are cities with a growing international population
• While Nigerians head into China, many Chinese are heading to the Middle East and Africa
• Some cities, such as those in China, have seen rapid expansion in recent years, in part because of a huge increase in migration
