World Population Day is observed every year on the 11th of July to bring to the public’s attention the issue of the growing global population. With world resources depleting at an unsustainable rate, overpopulation can be potentially disastrous. When we speak of overpopulation, we refer to a situation where the Earth cannot recoup the resources used by the world’s population every year. Consequently, this and overconsumption are at the root of everything–from our economy to other primary issues such as climate change, social unrest, etc.

Accordingly, Real Research, the online survey app, launched a survey on World Population Day. This survey explores how population determines the economy of a nation. If overpopulation persists as an issue? And, if yes, what is the primary impact of overpopulation? etc. Here are the results.


  • 38.75% said overpopulation causes the depletion of natural resources.
  • 51.1% believe improved education is one of the effective ways to solve overpopulation.
  • 49.93% of respondents fall under the classification of low income.
