"This chapter explores both the potential and limitations of the micro-computer as a research tool for unobtrusive data collection in the area of population and family planning....To provide concrete examples of the computer's potential usefulness as well as its limitations, two research projects undertaken [in the United States] by the author and colleagues will be discussed....Each program offers different applications of how the computer can be used to: (1) evaluate programs; (2) collect descriptive data about users' values, decisions, and previous behaviors regarding sexual issues, and (3) develop and test cognitive and behavior models. Each application also offers examples of the limitations of the computer in terms of external validity issues (i.e., how representative are samples of persons who use the computer voluntarily), the need to check the validity of responses typed by computer users, and ethical issues involved in using the computer to collect data."

"A new tool for epidemiological, demographic, and genetic research--the Canadian Birth Data Base--is being developed at Statistics Canada. Over a million live birth and stillbirth records for the period 1987-89 received from all provincial and territorial offices of vital statistics are being processed in a form suitable for linkage with other files. Maternal, child health, occupational, and environmental concerns...could be investigated. Associations between socio-economic indicators (e.g., parental income, education, and occupation) and unfavourable birth outcomes could also be studied in the future....It is planned to update the data base annually....This paper describes some of the reasons why such a file is required, the work in progress for its creation, and some of its potential statistical uses."

"Several [computer] programmes are described with demographic input data yielding demographic charts, life tables, projections etc....This paper presents some of the software developed at the University of Alberta with illustrations....The programmes...are for the construction of population pyramid, life tables and for making population projections." Copies of these programs are available from the author on request.

"This document describes an alternative format for data from the [1976] First Malaysian Family Life Survey (MFLS-1) wherein different card types have been split out into separate subfiles. Users of MFLS-1 data may find this multiple-subfile format easier to use [and more comparable to the 1988 MFLS-2] than the original single-file hierarchical format....In addition, this document describes the repunched and revised MFLS-1 male migration history data...and describes four new files containing data not included on the original public release MFLS-1 tape....The four new data files contain some recall test questions and updated infant feeding and amenorrhea information for women with children under age three."

"Public Use Microdata Samples (PUMS) contain records representing 5% or 1% samples of the housing units in Puerto Rico and the persons in them. Selected group quarters persons are also included. The file contains individual weights for each person and housing unit which, when applied to the individual records, expand the sample to the total population....Both the 5% and 1% samples have the same subject content and vary only in geographic composition of the Public Use Microdata Area (PUMA)." The population data concern language ability, age, children ever born, citizenship, educational status, employment, income, literacy, marital status, migration, occupation, and place of birth.

This is an introductory users guide to Supermap, which is a database management system as well as a mapping program. "Supermap is a system which is used with many different databases. While this document is mainly concerned with the Australian Censuses of Population and Housing for 1981 and 1986 (called CDATA86) it can also be used with the Australian Agricultural censuses (ADDS), the Australian Municipal Information System (AMIS), the population censuses of the U.S.A., New Zealand, Hong Kong and many others. Every data base presents information in a slightly different format so there are minor differences, mostly to do with retrieving data, from each database."
