Birth rate
According to the CIA's "The World Factbook", the country with the highest birth rate is Niger at 6.49 children born per woman and the country with the lowest birth rate is Taiwan, at 1.13 children born per woman.
Sex-selective abortion
The estimates for birth sex ratios, and thus derived sex-selective abortion, are a subject of dispute as well. For example, United States' CIA projects the birth sex ratio for Switzerland to be 106, while the Switzerland's Federal Statistical Office that tracks actual live births of boys and girls every year, reports the latest birth sex ratio for Switzerland as 107. Other variations are more significant; for example, CIA projects the birth sex ratio for Pakistan to be 105, United Nations FPA office claims the birth sex ratio for Pakistan to be 110, while the government of Pakistan claims its average birth sex ratio is 111.
