Below is a brief summary of revisions for countries experiencing more than a 500,000 change from the previously estimated 2010 population.

  • Albania’s population in 2010 is estimated to be 672 thousand (18 percent) lower than in the previous update.  This is due to higher estimates of migration during the 1990s and early 2000s based on a reassessment of trends in census and survey data.
  • Bangladesh’s population in 2010 is estimated to be 1.9 million (1 percent) lower than in the previous update due primarily to a reassessment of international migration levels in the 1980s and to a lesser extent in the 1990s.
  • Iran’s population in 2010 is estimated to be 9.9 million (15 percent) higher than in the previous update.  This change is due to revisions in international migration estimates of Iranian nationals and of Afghan and Iraqi refugees.
  • Laos’ population in 2010 is estimated to be 626 thousand (9 percent) lower than in the previous update.  This decrease is due primarily to lower fertility estimates based on the 2005 census results and increased out-migration based on destination country statistics.
  • Malaysia’s population in 2010 is estimated to be 2.1 million (8 percent) higher than in the previous update due to increased levels of both fertility and international migration.  Estimates of fertility were revised to match trends in vital statistics.  Migration estimates were updated to match trends in economic and refugee migration, as well as effects from the 2004 tsunami.
  • Pakistan’s population in 2010 is estimated to be 7.1 million (4 percent) higher than in the previous update due to the inclusion of the disputed areas of Azad Kashmir and Gilgit-Baltistan.
  • Saudi Arabia’s population in 2010 is estimated to be 2.5 million (9 percent) lower than in the previous update primarily as a result of revisions to fertility.  Fertility estimates decreased based on information from the 2004 census.
  • Senegal’s population in 2010 is estimated to be 1.7 million (13 percent) lower than in the previous update.  The change is attributable to a revision in non-refugee migration based on increased destination country data and intercensal change in Senegal from 1988 to 2002.
  • Spain’s population in 2010 is estimated to be 6.0 million (15 percent) higher than in the previous update.  This is due primarily to higher estimates of net immigration.  In addition, estimates of fertility increased and mortality decreased based on recent vital statistics.
  • Sudan’s population in 2010 is estimated to be 2.0 million (5 percent) higher than in the previous update.  This change is due to an increase in fertility based on recent surveys and a census.  Furthermore, recent data on refugees and economic migrants resulted in a reduction in net out-migration.
  • United Kingdom’s population in 2010 is estimated to be 1.1 million (2 percent) higher than in the previous update.  This is due primarily to higher estimates of net immigration based on recent data.  Also, mortality is reduced following incorporation of recent vital statistics.
  • Zambia’s population in 2010 is estimated to be 1.4 million (12 percent) higher than in the previous update.  This is due to lower estimates of both the non-AIDS and with-AIDS mortality based on a reassessment of trends in survey data.  We also increased our fertility estimates based on recent surveys and the 2000 census.

This release also contains minor revisions to age-specific fertility rates for these 6 countries.

  • Anguilla
  • Bermuda
  • Saint Pierre and Miquelon
  • Thailand
  • U.S. Virgin Islands
  • Montserrat
