The quality and reliability of official demographic data are also affected by public trust in the government, government commitment to full and accurate enumeration, confidentiality and protection against misuse of census data, and census agencies' independence from political influence. Because the five-year age group is the cohort unit and five-year period data are used, interpolations to obtain annual data or single age structure may not reflect actual events or age composition. Population estimates are from demographic modeling and so are susceptible to biases and errors from shortcomings in the model and in the data. The cohort component method - a standard method for estimating and projecting population - requires fertility, mortality, and net migration data, often collected from sample surveys, which can be small or limited in coverage. Limitations and Exceptions: Current population estimates for developing countries that lack recent census data and pre- and post-census estimates for countries with census data are provided by the United Nations Population Division and other agencies. These territories share a relatively small area and a high urbanization level, with an economically specialized city population drawing also on rural resources outside the area, illustrating the difference between high population density and overpopulation. Several of the most densely populated territories in the world are city-states, microstates, or dependencies. Considering that over half of the Earth's land mass consists of areas inhospitable to human inhabitation, such as deserts and high mountains, and that population tends to cluster around seaports and fresh water sources, a simple number of population density by itself does not give any meaningful measurement of human population density. Population density is a measure of the intensity of land-use, and can be calculated for a block, city, county, state, country, continent or the entire world. Errors and undercounting occur even in high-income countries in developing countries errors may be substantial because of limits in the transport, communications, and other resources required conducting and analyzing a full census. Estimates for the years before and after the census are interpolations or extrapolations based on demographic models.

Land area is a country's total area, excluding area under inland water bodies, national claims to continental shelf, and exclusive economic zones.
