This section presents a series of 23 manuals and guides of demographic methods and techniques issued by the United Nations over a long period of time. These manuals and guides fall into six clusters. For each cluster the opening page contains a short introduction and a hyperlinked list of manuals. The pages for each manual include a short introduction, chapter-level table of contents hyperlinked to respective files in pdf format and links to thematically related manuals.
The manuals on this site are concerned with formal descriptive, analytical and projection methods with an emphasis on techniques adapted to or specially designed for the countries with insufficient, unreliable or untimely data. The behavioural aspects or their socio-economic determinants are outside the scope of this series.
