Tendencias recentes na metodologia de levantamentos demograficos em pai ses em desenvolvimento

This report summarizes these advances and critically examines their applicability to the collection of demographic data in developing countries. Each of three methodologies for direct collection of data - interviews with one person, or with more than one person, or collection of information from more than one source (e.g., from both civil registers and house visits) - is weighed for its respective advantages and disadvantages. The advantages and drawbacks of four methodologies for the more rapidly accomplished indirect collection of data and the use of statistical modeling to calculate infant mortality from statistics on infant survival are also discussed. It is noted that in spite of greater inaccuracies inherent in the single interview technique, this, due to its low cost and ease of application, is the methodology most used in developing countries to derive vital statistics. For many methodologies, greater accuracy can be gained through improved questionnaires and better trained interviewers. A 29-item bibliography (1949-80) is included.
