National electronic information space (national electronic space) is a complex object, which consists of a distributed information resources of different categories, including the personal data, management systems, regulations, procedures and infrastructures, as well as the interaction (relationship) between them. This complexity makes it necessary to apply object-oriented approach and the principle of decomposition to internet management problem. This study identifies and segments base components of the architectural model of the national electronic space; models segment of personal data of the e-space and identifies its management systems and functionality blocks for the "population" domain of e-government; models individual information segment on national e-space, identifies functionary schemes for “population” domain of e-government; proposes  solutions for the architecture of field-based(and inter-agency) information systems and for the models of e-services in the "population" domain of thee-government.
