First billion humans earth reached in 1804. Second billion in 1927 (after 123 years). For third billion earth population needed only 33 years - 1960. Fourth billion was reached in 1974 and only 14 years were needed. For 5th billion we needed only 13 years (1987). And 6th billion was the fastest, only 12 years needed, reached in 1999. Same intervall we needed for seventh billion (2011). And we are growing to 8th billion (probably in 2024). This table gives you quick overview:

Since middle of the 20th century world population growth exponential. Africa population don't show any slowing tender, that is big load for this continent. Long-term global population growth is difficult to predict. According to official estimates by UN, world population will reach 11 billions at the beginning of the 22th century and they predict that it will stabilise by then. Let's hope that Earth can feed this huge population..
