This is a list of countries and dependent territories ranked by population density, measured by the number of human inhabitants per square kilometer, and also sortable by total area and by population.
The list includes sovereign states and self-governing dependent territories based upon the ISO standard ISO 3166-1. The list also includes but does not rank unrecognized but de facto independent countries. All 193 member states of the United Nations plus the Vatican City are given a rank number. The figures in the following table are based on areas including internal bodies of water such as bays, lakes, reservoirs and rivers.
The list does not include entities not on ISO 3166-1, except for states with limited recognition. Thus constituent countries that are not included on ISO 3166-1, and other entities not on ISO 3166-1 like the European Union, are not included.
Figures used in this article are mainly based on the latest censuses and official estimates or projections. Where these are unavailable, projections provided by the Population Division of the United Nations Department of Economic and Social Affairs are used.
