Below is a brief summary of revisions for countries experiencing more than a 500,000 change from the previously estimated 2013 population.
The estimated population of Burundi in 2013 is 10.1 million, which is 828 thousand (7.6 percent) lower than our previous estimate. This decrease is due to higher estimates of mortality and lower estimates of net migration, especially since 2003.
The estimated population of Cameroon in 2013 is 22.5 million, which is almost 2 million (9.7 percent) higher than our previous estimate. This increase is due primarily to higher estimated fertility, especially since 2003.
The estimated population of Mexico in 2013 is 118.8 million, which is 2.6 million (2.2 percent) larger than our previous estimate. The higher estimate is due primarily to lowered estimates of emigration from Mexico since 2000.
The estimated population of Sweden in 2013 is 9.6 million, 528 thousand (5.8 percent) higher than our previous estimate. The increase is due to higher estimates of immigration since 2000 and higher estimates of fertility since 2003.
