This site allows modelling of future world populations.

The main motivation for creating this site is to  demonstrate that a peak population of 9 billion by 2050 and then falling away is very unlikely.

It will likely be much higher !!....possibly 20-25 billion

The difficulty comes from Africa where continuing high birth rates may result in continuing population increase to 2200. The other continents will all likely have falling populations by 2100.

  Site provides the following options :

| World |     Compare world populations projections. Precalculated for a range of scenarios.
| Continent | Compare continent population projections. Precalculated for a range of scenarios.
| Region | Region population projections. Allows user input of projection parameters
| Country | Country population projections. Allows user input of projection parameters
| Discussion | Details data sources .... methodology etc.
| Contact me | E-mail comments...improvements...etc regarding the site.
  Primary data source UN excel data sheets (1950-2010)
   All data projections (2010-2200) are the responsibility of this site. They are not in any way to be attributed to the UN.
