The population of Poland in the last 20 years has caused many years of recorded growth and decline with the population. The recorded population of Poland between 2002 and 2006 had shown a decreasing trend while between 2007 and 2012 the population had an increasing trend. [ 106 ]
The table starts counting approximately 10,000 years before present, or around 8,000 BC, during the middle Greenlandian, about 1,700 years after the end of the Younger Dryas and 1,800 years before the 8.2-kiloyear event. From the beginning of the early modern period until the 20th century, world population has been characterized by a rapid growth.

In world demographics, the world population is the total number of humans currently alive. It was estimated by the United Nations to have exceeded eight billion in mid-November 2022. It took around 300,000 years of human prehistory and history for the human population to reach a billion and only 218 more years to reach 8 billion.
The Indigenous population of the Americas in 1492 was not necessarily at a high point and may actually have already been in decline in some areas. Indigenous populations in most areas of the Americas reached a low point by the early 20th century. [20]
A falling population also lowers the rate of innovation, since change tends to come from younger workers and entrepreneurs. [10] Strain on mental health. Population decline may harm a population's mental health (or morale) if it causes permanent recession and a concomitant decline in basic services and infrastructure. [12] Deflation.
Based on this, the UN projected that the world population, 8 billion as of 2023, would peak around the year 2086 at about 10.4 billion, and then start a slow decline, assuming a continuing decrease in the global average fertility rate from 2.5 births per woman during the 2015–2020 period to 1.8 by the year 2100 (the medium-variant projection).
[3] [4] Old estimates put the global population at 9 billion by 2037–2046, 14 years after 8 billion, and 10 billion by 2054–2071, 17 years after 9 billion; however these milestones are likely to be reached far sooner.
