Introduction The inevitable waves transferring into a certain cycles are characteristics o f development o f any science. The growth periods are followed by decline periods, revival periods are interleaved with depression periods, accumulation o f mass data— with scientific break ins, scientific break ins — w i t h long respites and new ways o f accumulation o f primary knowledge. The present stage o f development o f domestic statistics is characterized by the extreme concentrated accumulation o f valuable and huge (on its scales) mass o f primary data, the level o f their scientific generalization and factor o f their practical use are low. The time o f further accumulation o f primary data without their proper generalization for a long time is in the past as completely senseless, without any practical significance neither now, nor hereafter. It is time for applied generalizations in domestic statistics, upon which it is possible to break into the increase o f efficiency o f use o f statistical data, to the transformation o f statistics not only into the high-power tools o f knowledge or (that can be met more often—falsification), but also into a tool o f exact identification and transformation o f present—day reality. Just today statistics must and can "say a weighty w o r d " in contrast to contradictory and false valuations o f the entourage. Taking into account a large number o f statistical publications and data, it has acquired some kind o f right to be the arbiter and to bear the authoritative judgment about it, to act not only as a tool, but also as a catalyst o f forthcoming break ins and changes, w i t h which the modern world is overflowed. For fulfilment o f this special, principal mission the modern domestic statistics should unite all the collected data in the object form and present all the accumulated information. T o unite all the data, to present all the accumulated information as a unit is that most difficult thing, which exists in any science and in any branch o f practical activity. T o unite things done in different time and for various reasons is always difficult and especially difficult in statistics, where everything was made o f small pieces, where theory and practice were developing in different ways, where all the data and knowledge, being dead materials, were becoming out o f date and loosing practical significance. The history o f statistics (as a science, and as a branche o f practical activity) abounds the certificates o f similar outcome, its archives are oversaturated by not used researches and data, which consists o f a lot o f useful information. Sometimes it is difficult to connect things created by different people and in different years not only in the whole science or in the whole branch of practical activity, but also in the activity o f a separately taken scientific collective or department. 20
