World population expected to hit 8 billion on Nov. 15

The world's human population is expected to reach 8 billion on Tuesday, according to a United Nations report released earlier this year.

The United Nations will host events on Tuesday to mark "milestone in human development" that is the "Day of Eight Billion," according to NEXSTAR. The population cleared 7 billion just 12 years ago and is expected to reach 9 billion in another 15 years.

"This is an occasion to celebrate our diversity, recognize our common humanity, and marvel at advancements in health that have extended lifespans and dramatically reduced maternal and child mortality rates," U.N. Secretary-General Antonio Guterres said in July, per the outlet. "At the same time, it is a reminder of our shared responsibility to care for our planet and a moment to reflect on where we still fall short of our commitments to one another."

The milestone will come as international representatives meet for the COP27 climate summit and float a draft agreement to establish an international climate damage fund that would compensate poorer countries, often some of the most densely populated, for climate-related damages. Many details, including funding sources and damage amounts, remain undetermined and the plan is likely to stall in the international community, barring extensive revisions.

Approximately 70% of births occur in low-income and lower-middle-income nations, NEXSTAR observed. Those countries will account for 90% of global population growth in the 15-year period leading up to the projected 9 billion figure. Many such countries would be beneficiaries under the draft U.N. plan.

Guterres previously warned that the growing population would bring global challenges and called on the international community to band together to address the issues that the milestone would present.

"Unless we bridge the yawning chasm between the global haves and have-nots, we are setting ourselves up for an 8-billion-strong world filled with tensions and mistrust, crisis, and conflict," he wrote last week in USA Today.
