Roman Catholic AnswerThe Vatican-Annuario reported in March 2012 that the worldwide Cahtolic population reached 1.196 billion, which means that Catholics as a percentage of the global population "remained stable at around 17.5 percent." See the report at the link below.
The current human population of earth is ~6.7 billion. It is highly likely that 666 billion will never be reached (the earth simply could not support such a population). If by population we mean to take into account ALL life....it is an impossible number to calculate. If there was intended to be a decimal place in there for 6.66billion - The US and UN census information both agree that it was hit in 2005. An exact date would be highly debateable - as is the accuracy of these estimates.
The world population reached the high mark of 5 billion people in the year of 1974 but it keeps on increasing everyday since more people are being born.
