A microstate or ministate is a sovereign state having a very small population or very small land area, and usually both. As the meaning of neither "state" nor "very small" is clear, 2010s attempts to define microstates focus on identifying political entities with unique qualitative features linked to their geographic or demographic limitations. According to a qualitative definition, microstates are: "modern protected states, i.e. sovereign states that have been able to unilaterally depute certain attributes of sovereignty to larger powers in exchange for benign protection of their political and economic viability against their geographic or demographic constraints." In line with this and most other definitions the examples of microstates include: Liechtenstein, Monaco, San Marino, Niue, Andorra and the Federated States of Micronesia.
The smallest political unit recognized as a sovereign state is Vatican City, with 842 citizens as of July 2013 and an area of only 0.44 km². However, some scholars dispute qualifying Vatican as a state arguing that it does not meet the "traditional criteria of statehood" and that the "special status of the Vatican City is probably best regarded as a means of ensuring that the Pope can freely exercise his spiritual functions, and in this respect is loosely analogous to that of the headquarters of international organisations."
Microstates are distinct from micronations, which are not recognized as sovereign states. Special territories without full sovereignty, such as the British Crown Dependencies, the Chinese Special Administrative Regions and overseas territories of Denmark, France, the Netherlands, Norway and the United Kingdom, are also not considered microstates.
In statistical mechanics, a microstate is a specific microscopic configuration of a thermodynamic system that the system may occupy with a certain probability in the course of its thermal fluctuations. In contrast, the macrostate of a system refers to its macroscopic properties, such as its temperature, pressure, volume and density. Treatments on statistical mechanics, define a macrostate as follows. A particular set of values of energy, number of particles and volume of an isolated thermodynamic system is said to specify a particular macrostate of it. In this description, microstates appear as different possible ways the system can achieve a particular macrostate.
A macrostate is characterized by a probability distribution of possible states across a certain statistical ensemble of all microstates. This distribution describes the probability of finding the system in a certain microstate. In the thermodynamic limit, the microstates visited by a macroscopic system during its fluctuations all have the same macroscopic properties.

Hackworth had arrived at the point where he frankly didn't care, and so he stared directly at these men, front-line soldiers of their various microstates, as each one primly folded his navy blue suit jacket and elbow-crawled into a coffinlike microcabin like a GI squirming under a roll of concertina wire, accompanied or not by a camp follower.
