Population dynamics is the type of mathematics used to model and study the size and age composition of populations as dynamical systems.Population dynamics is a branch of mathematical biology, and uses mathematical techniques such as differential equations to model behaviour.
Human Dynamics as a branch of statistical physics: Its main goal is to understand human behavior using methods originally developed in statistical physics.
Successive dispersals of Homo erectus greatest extent (yellow), Homo neanderthalensis greatest extent (ochre) during Out of Africa and Homo sapiens (red, Out of Africa II), with the numbers of years since they appeared before present.
Estimates of world population by their nature are an aspect of modernity, possible only since the Age of Discovery.Early estimates for the population of the world [10] date to the 17th century: William Petty, in 1682, estimated the world population at 320 million (current estimates ranging close to twice this number); by the late 18th century, estimates ranged close to one billion (consistent ...
Sapiens: A Brief History of Humankind (Hebrew: קיצור תולדות האנושות, Qitzur Toldot ha-Enoshut) is a book by Yuval Noah Harari, based on a series of lectures he taught at The Hebrew University of Jerusalem.
Population decline, also known as depopulation, is a reduction in a human population size. Throughout history, Earth's total human population has continued to grow; however, current projections suggest that this long-term trend of steady population growth may be coming to an end.
Log-log graph depicting estimates of the world population from 10,000 BCE to 2000 CE. Prehistoric demography, palaeodemography or archaeological demography is the study of human and hominid demography in prehistory.
Human overpopulation (or human population overshoot) is the idea that human populations may become too large to be sustained by their environment or resources in the long term.
