Data visualization of the population in countries around the world based on World Population Prospects data. "India's population will surpass China's in 2023. Earth's population will be 8.5 billion in 2030 and 9.7 billion by 2050. As fertility rates continue to decline in most developed countries, nearly all population growth in the next 20 years will happen in low and lower-middle-income countries, most of which are in sub-Saharan Africa."
