Abstract
The System of National Accounts (SNA) is processed statistics, created from various primary statistics. Therefore, quality and quickness of SNA depends on the quality and publication dates of these statistics. Designs and publication dates of primary statistics are incompatible with SNA's specification, because, governmental administration for the statistics is in a very dispersed environment. The author proposes an estimation method for SNA that uses "atomdata" for improving its quality and timeliness.
