World Population Day – July 11, 2021

World Population Day on July 11 is a holiday that’s dedicated to focusing on the importance of population issues. The day was established by the United Nations as a result of the massive interest people had in Five Billion Day in 1987. Read on for more information about observing this important holiday.

When is World Population Day 2021?

World Population Day is observed annually on July 11.

History of World Population Day

Sure, you might know that there are more than seven billion people on earth right now, but how often do you stop to think about what that really means? Five Billion Day, in 1987, was meant to acknowledge the date on which the world’s population reached an estimated five billion people, which supposedly happened on July 11 of that year (hence the annual date for World Population Day). And look how much the population has increased since then! Population issues cover a lot of territories, from family planning, gender equality, and environmental impacts to human rights concerns. 

World Population Day was established in 1989 by the Governing Council of the United Nations Development Programme — UNDP. The inspiration for this holiday was the peaking public interest in the celebration of ‘Five Billion Day’ on July 11, 1987. This original date was decided to be set as ‘World Population Day’ by the United Nations General Assembly, and resolution 45/216 made this official in December 1990.

World Population Day serves to highlight the growing problems that come with a growing global population. Overpopulation is a crucial issue, especially considering that world resources are depleting at an unsustainable rate. Awareness about the effects of overpopulation on development and nature is emphasized. The increasing population also sheds light on health problems faced by women during pregnancy and childbirth, making the need for family planning, gender equality, and maternal health more important than ever.  

The issue of population is also causing strain on society: heinous crimes are happening more than ever in the areas of gender inequality and human rights, especially in developing countries. Leadership is already doing a subpar job at taking care of its citizens, and as more people come into the world, violations such as human trafficking and child labor are increasingly becoming normal.

How do we celebrate Population Day?

World Population Day is all about raising awareness of controlling the population, and the risks and consequences of a disproportionate population-to-resources ratio. The issue is discussed on social media the most, so if you have a blog or other social platform for raising awareness, raise your voice on how to take precautions and combat population issues. 

How to Observe World Population Day

  1. Educate yourself

    There is an enormous amount of information out there about population issues, so use World Population Day to do some research. A great place to start is with the United Nations Populations Fund, the lead UN agency for tackling population issues. We know there is a wide breadth of resources, so choose a few that really interest you and take a deep dive into their problems and potential solutions.

  2. Then share that information with your networks

    As we said earlier, if you live in a developed nation, you probably aren’t that affected by population issues, at least in ways that are visible in your day-to-day life. That means your friends, family, and followers probably aren’t, either. Use World Population Day to ask people to have a good long think on these issues, and what they can do to help. If you’re posting on social media, make sure to hashtag it with #worldpopulationday.

  3. Donate to organizations focused on population issues

    There are so many amazing nonprofits and NGOs out there that are doing tough work on population issues every single day, especially in the developing world. They include organizations that educate women about contraception and family planning, ones that help people lift themselves out of poverty, and ones that help refugees that have fled their homes because of environmental issues or human rights abuses. If you are able, find ways to donate your time and/or your money to these heroic organizations.

5 Amazing Population Facts

  1. The rate at which population grows

    The world population increases by about 83 million people every year.

  2. A change in pattern

    The population in Africa is growing, whereas the European population is shrinking.

  3. Monaco has the most dense population in the world

    While it is the second smallest independent state in the world, its population is a staggering 39,500, which is about 68,212 people per square mile.

  4. Life expectancy is unexpectedly increasing

    In 2000, the average global life expectancy was 67 years old. Fast forward 20 years, and it increased to 72.

  5. Millennials make up 27% of the world’s population

    About two billion people all over the world are part of this generation.

Why World Population Day is Important

  1. It touches everyone

    If you live a comfortable lifestyle in a first-world country like the United States, you probably don’t think of population issues having that much of an effect on your life. However, the more people are added to the population, the more power and food is needed to sustain all of them. It’s hard to keep up that food and power production at the rate that the population is growing, and efforts to do so are contributing greatly to climate change, which affects you no matter where you live.

  2. It asks us to look forward

    World Population Day obviously reminds us to look at the current population and population issues that influence how people live now. However, it’s really focused on the future, and what efforts it will take to slow population growth. The most important thing to think of is what the world will look like for your kids, grandkids, great-grandkids, etc. if the population continues to grow at this rate.

  3. There’s a big disparity in how population issues affect different countries

    Population issues disproportionately affect people in developing countries. For instance, did you know that people in very poor countries have a life expectancy that’s about 20 years shorter than people in rich, developed countries? How about that 1/3 of population growth is due to unplanned pregnancies, which often happen when people are lacking education and family planning services? World Population Day is a good reminder to step outside ourselves and focus on these important issues.
