The2008 rate of growth has almost halved sinceits peak of 2.2% per year, which was

Europe (mainly due tolow fertility rates)and Southern Africa (due tothe high number ofHIV-related deaths). Within thenext decade, Japan and

some countries in WesternEurope are also expectedto encounter negativepopulation growth dueto sub-replacementfertility rates.

In 2006, the UnitedNations stated that the rateof population growth isdiminishing due tothe demographic transition.If this trend continues, the

rate of growth may diminishto zero, concurrent with aworld population plateau of9.2 billion, in 2050.
