Abstract

The City Hall of Juiz de Fora had its Project of new property registration approved by the National Program of Support to the Administrative and Fiscal Management of the Brazilian Cities (PNAFM). This new registration is one of the necessary actions to Property Registration for the future implantation of Multiple Purposes Registration. A statistical treatment of Property Registration will make possible the generation of information that can give support to the decisions of the public administration in Juiz de Fora, also supporting the new registration that will have beginning in February of 2008. This work statistically treats the database of property registration (197,230 property units) of the city of Juiz de Fora through the study and application of multivariate analysis statistics techniques, more specifically the factor analysis and the cluster analysis. The statistical treatment will make possible such a reduction of the universe of variables, as an analysis of segmentation of the tax units in groupings of similar profiles. This reduction of the dimension of registration is capable to generate trustworthy information for the public manager. It is hoped that they assist in the future analyses of measuring the tax potential, adopting a new modeling calculation that considers the similarities of the properties.
