Normally breeding is substantially more. The list includes independent countries This is a list of sovereign states, containing 203 entries, giving an overview of states around the world with information on the status and recognition of their sovereignty.

Figures used in this chart are based on the most recent estimate or projection by the national census authority where available and usually rounded off. Where national data is unavailable, figures are based on the July 1, 2009 estimate by the Population Division of the United Nations Department of Economic and Social Affairs The United Nations Department of Economic and Social Affairs is part of the United Nations Secretariat and is responsible for the follow-up to the major United Nations Summits and Conferences, as well as services to the Economic and Social Council and the Second and Third Committees of the United Nations General Assembly.[3] Because the compiled figures are not collected at the same time in every country, or at the same level of accuracy Statistics is the formal science of making effective use of numerical data relating to groups of individuals or experiments. It deals with all aspects of this, including not only the collection, analysis and interpretation of such data, but also the planning of the collection of data, in terms of the design of surveys and experiments, the resulting numerical comparisons may result in misleading conclusions. Further, the addition of all countries may not equal the world total.
Sovereign states are listed in bold text and dependent territories in italic. States listed that do not have general recognition are in bold and italic.
