2020 World Population Data Sheet

In 2020, the world’s 7.8 billion inhabitants have experienced how population density in urban areas, household size, and population aging contribute to our vulnerability to pandemics as we grappled with the novel coronavirus and the disease it causes, COVID-19. Looking ahead, the United States’ population is projected to increase between 2020 and 2050, but at a much slower pace than recent decades. China’s population is projected to decrease by 2050, while Benin and Niger may see a population increase of 150% or more.
