Excerpted from the original article, by Carl Haub, on the Population Reference Bureau’s Behind the Numbers blog:

Taiwan’s government has just announced that the country’s total fertility rate (or TFR, the average number of children a woman would bear in her lifetime if the birth rate of a particular year were to remain unchanged) in 2010 was the lowest in its history at 0.91 children per woman. It’s the lowest rate any country has ever reported in history. The announcement itself is a bit of a projection since births have been officially reported only through November 2010. The country’s TFR had declined to 1.1 in 2005 and had remained there through 2009.
