[Collection of obstetrical data in international cooperation]

Authors deal with the question of collecting obstetrical data within the framework of international co-operation. They mention that data collecting by individual obstetrical institutes is not suitable for getting reliable data on the degree of development of major geographical regions or countries in the field of obstetrical provision. Instead of this the authors suggest to acquire obstetrical-geographic data of central statistical institutes of the individual countries and to evaluate them in a centralized way.
