There is a specification of a minimum number of inhabitants for statehood.

The lack of a permanent population is enough to affect the existence
of a state. 

Non-existence of fixed boundaries is enough to affect the existence of a state. 

It is necessary for an entity to have exactly defined or undisputed boundaries to be a state at the time when it comes into existence.

For the existence of a state, it is enough that this territory has a sufficient consistency, even though its boundaries may not have been precisely defined or delimited.
