INTRODUCTION AND ACKNOWLEDGMENTS
The first version of PRODEMOG, published in 1989(*), and successive versions presented
partially in scientific meetings and educational activities, utilized BASIC for the programming.
PRODEMOG 3.0, which retains many newly integrated and improved programs from the
original package, is now configured in Visual Basic, thereby becoming easier and faster
to use in the environment Windows. Some of the basic research necessary for the
development of this version, has been partially financed by the National Research Council
(C.N.R) and the Ministry of Scientific Research, Italy.
The following researchers and colleagues (listed in alphabetic order) collaborated with me
in the revision and verification of the programs: Patrizia Accordi, Riccardo Aldinucci,
Giovanna Barcaro, Mario Berti, Enrico Bonci, Giovanna Campisi, Alessandro Chini,
Leonardo Ferri, Luigi Fontani, Maurizio Garosi, Cesare Giachetti, Flavio Giannetti, Riccardo
Giannetti, Matteo Juliani. To all, and to the students who participated in seminars and courses given on this subject, a sincere thanks.
Particular thanks to Andrea Menchiari who provided indispensable help in the preparation of
many programs. A special acknowledgement is due to Linda Mesh for the translation of the
manuscript from Italian to English.
The planning of PRODEMOG 3.0 in Visual Basic was realized and revised by a group of five
young experts, who worked with great diligence and total professionalism.
The actual complexity of scientific research requires a process of teamwork where there
is the amalgamation of related abilities and yet differing professional specializations. The
cover design, with the work of Mr. J. J. Sempe`, whom I thank for his permission for
reproduction, is a symbolic rendition of the idea behind this process: the planning, the
execution, the formation and finally, the thanks. All of these are criterion that we try to
respect as we wait for the critique. The current version of PRODEMOG 3.0 lacks certain
characteristics, such as a specific text editor, which we hope to include in a future version.
Any questions, notice of bugs discovered and suggestions are welcome.

(*) Petrioli, L. (1989), "Demographic software. PRODEMOG", Institute of Statistics, Faculty
of Economic Sciences and Banking, University of Siena, Italy. This version united in an
organized form various programs prepared by the same author for a training course for
experts regarding the collection and elaboration of data, held in 1987 at the Department
of Demography, University of Kinshasa, Democratic Republic of Congo (formerly Zaire).
The use of BASIC was a fundamental achievement in the realization of demographic
software, due to the simplicity of the language and by the computer-friendly program operation.
PRODEMOG 3.0, which is dedicated to the
solution of various demographic problems, has the
Main use: education and research application;
User skill: subject intermediate level:
Computer: medium skill level.
The evaluation of the parameters of the functions utilized for their adaptation to observed distributions relative either
to life tables or to age-specific fertility rates, was determined with iterative and other methods such as least squares, passage
of theoretic function between characteristic points, and computation of the areas of the observed data.
The same procedure has often been applied for mortality and for population projection studies. Especially for the fertility function, it is possible to follow on the computer desktop the stages which explain the iterative process in a dynamic way; that is, the movements of the theoretical curve as it tries to approach the observed data.
Each program in this version of PRODEMOG contains several sample files for demonstration purposes, but
additional files can be created by organizing data into the layout structure, being careful to follow the necessary
spacing for the heading, labeling, and listing of data.
The Archives is composed of a collection of data files, some of which represent a broad collection of demographic data such as life-tables, fertility rates (2513 distributions) and censuses (111 surveys), for more than one hundred countries.
For mortality, there are three data files which contain 624 life-tables each, for females, males and unisex, respectively.
At the end of the manual, a codification of various countries of the world is listed, followed by a glossary of the main concepts, terms and symbols used in PRODEMOG.
