The very high and steadily increasing world population is a problem in many ways: environmental impact, poverty, and armed conflict are just a few of many adverse effects of a population arguably growing past Earth's comfortable carrying capacity.
As shown in UN projections, the 2015 population of 7.35 billion is slated to grow to 8.1 billion in 2025. This represents a growth of between 75 (in 2025) and 83 (in 2016) million people per year. It is based on 18.6 (2015-2020) and 17.5 (2020-2025) births/year/1000 people and 7.8 (2015-2020) and 7.9 (2020-2025) deaths/year/1000 people.
While population growth is problematic, it is a bit like aging: the alternative is very likely worse! In this question we ask:
Will the world population grow every year from 2016-2025?
A negative resolution would require either a significant decrease in the birth rate, or significant increase in the death rate. The latter could occur due to a global pandemic, war, or other calamity causing tens of millions of additional deaths in a year. A lower birth rate is also conceivable, e.g. if the Zika virus were to significantly decrease or forestall pregnancies worldwide. Population numbers to be taken from UN data.
