The world population was 7.349 billion as of 1 July 2015, according to the UN Population Prospects: 2017 Revision report. This estimate is based on the de-facto definition of population counting all residents of countries regardless of their legal status or citizenship. The global population has almost tripled during the last 65 years, but because of the declining population growth rate since 1970 it will take more than 200 years for the population to triple again. By 2100, the global population is expected to be only half as much as it is now. The world’s population is currently made up by the residents of 196 independent countries plus about 60 dependent territories. However, nearly 60 percent of the world's population (58%) live in the 10 most populated countries. Among them, the largest country by population in the world is China, which accounts for 19 percent of the total global population. China is followed by India (18%) and the United States (4%).China PopulationIndia...

HelpAge International has created the Global AgeWatch index to give voice to older people in defining the post-2015 UN sustainable development goals. This index assesses 96 countries worldwide on how well they provider their aging populations with decent, active, and healthy lives and enable policymakers to make the necessary steps to improve the well-being of older people. The welfare of older people globally is important not only because of the expected growth of this age group in the decades to come but because people do not stop developing when they reach ago 60. Older population have the same rights as younger people to live in environments that foster this development.
