the world population passed the six-billion mark. By February 2020, the official world population had jumped over the seven-billion mark to an estimated 7.76 billion, according to Worldometers, a world statics website operated by an international team of developers, researchers, and volunteers....
Our projection strategy advances urban-population research by producing urban-size projections—for agglomerations around the world—that correctly obey empirically observed distribution laws. Although our method is very simple and omits various aspects of urbanization, it nonetheless yields valuable insight ...

Because world population growth is marked by differing trends in the more developed and developing regions, the successful solution of future social and demographic problems will depend, in all likelihood, on whether population growth is considered in isolation or as a problem which is inextricably in...

Over the last 20 years many urban areas have experienced dramatic growth, as a result of rapid population growth and as the world's economy has been transformed by a combination of rapid technological and political change. Around 3 billion people—virtually half of the world's total population-...
Population projectionsFertilityDemographic transitionAge structureContraceptionPast, current and projected future population growth is outlined. Barring a calamitous pandemic, a further increase in the world's population from 7 to between 8.8 and 10 billion by mid-century is unavoidable. This increase is...

Species’ vulnerability to extinction is strongly impacted by their geographical range size. Formulating effective conservation strategies therefore requires a better understanding of how the ranges of the world’s species have changed in the past, and h
population, with approximately 3 billion people (38% of the world’s current population) affected under an intermediate emissions scenario and 5 billion people (66% of the world population) under a high emissions scenario by the century’s end (or 35-61% using projections of future population)...
