T. Machine-Readable Data Files (MRDF)

References to data of demographic interest that are stored in machine-readable form. All MRDFs coded under this heading are cross-referenced to specific subject categories as appropriate. Articles concerned with the availability of MRDFs are also included.

54:10894 Cartwright, Ann; Lucas, S. Survey of Abortion Patients for the Committee on the Working of the Abortion Act, 1972 [MRDF]. Pub. Order No. 33054. [1972?]. Institute for Social Studies in Medical Care [producer]: London, England; University of Essex, ESRC Data Archive [distributor]: Colchester, England. In Eng.
This data set consists of three files: a patient file containing 272 cases, a doctor consultations file with 1,031 cases, and a file of other professional consultations containing 161 cases. The purpose of the survey creating this file was "to collect data from a random sample of women living in England, Wales and Scotland and having abortions in the spring of 1972 and to find out whom they had consulted in the process, the number of consultations, any delays involved and the reasons for them, and what the women felt about the way they had been treated." Data are included on a number of attitudinal, behavioral, and background variables.

54:10895 Gates, William A.; Witt, Barbara. Creating a database for demographic research: a case study. CDE Working Paper, No. 86-30, [1986]. 9 pp. University of Wisconsin, Center for Demography and Ecology: Madison, Wisconsin. In Eng.
This study is concerned with ways in which data bases can be utilized to support demographic research. The authors "report here specifically on the development of the PUS801000 database derived from the [U.S.] Census Bureau's 1980 Public Use Microdata Sample. The original dataset consists of over 11 million records for individuals and 4 million records for households....This case study documents a variety of strategies and tools for minimizing the resources required to support the PUS801000 database. Other issues addressed include how such databases can be extended to be of much greater use to researchers. Also discussed are the special needs of researchers and the problems they encounter in being direct users of INGRES QUEL."

54:10896 Levine, Ned. The construction of a population analysis program using a microcomputer spreadsheet. Journal of the American Planning Association, Vol. 51, No. 4, 1985. 496-511 pp. Washington, D.C. In Eng.
"This article describes a population analysis program called 'HALLEY,' which uses a microcomputer spreadsheet (Lotus 1-2-3). The program calculates a life expectancy table, an age distribution model, a fertility table, and five- and ten-year population projections; the four parts work in sequence. The program is appropriate for analyzing local, regional, state, or national populations and is also useful for teaching the interrelated dynamics of population change. Data for the program are readily available. 1-2-3 can make graphs from the population program, which makes it easy for the user to visualize population changes. The ease of use of such programs can be beneficial in planning analysis, allowing planners, administrators, and the public to examine population models in detail and to test the assumptions on which they are based."

54:10897 United States. Bureau of the Census (Washington, D.C.); United States. Bureau of Labor Statistics (Washington, D.C.). Current Population Survey, March 1987 [MRDF]. 1987. U.S. Bureau of the Census [producer and distributor]: Washington, D.C. In Eng.
This file contains 293,248 logical records (with a record length of 408 characters) and has accompanying documentation. The file structure is hierarchical, with a sort sequence by census state code and then by Metropolitan Statistical Area (MSA) or Primary Metropolitan Statistical Area (PMSA) code. "This file, also known as the Annual Demographic File, provides the usual monthly labor force data [for the United States], but in addition, provides supplemental data on work experience, income, noncash benefits, and migration. Comprehensive information is given on the employment status, occupation, and industry of persons 14 years old and over....Data on employment and income refer to the preceding year, although demographic data refer to the time of the survey. Characteristics such as age, sex, race, household relationship, and Spanish origin are shown for each person in the household enumerated."

This file contains 40,628 records (with a record length of 90 characters) and has accompanying documentation. "The file includes the geographic code identifier and name of each governmental unit [in the United States]; corrected total population (census complete-count) as of April 1, 1980; per capita income in 1979 (census sample); July 1, 1986 population estimates; and per capita income estimates for 1985. This file includes information for all states, counties, [and] incorporated places, [as well as] functioning minor civil divisions (MCDs) in 20 specified states."

54:10899 United States. National Bureau of Standards [NBS] (Washington, D.C.); United States. Bureau of the Census (Washington, D.C.). MSA: Metropolitan Statistical Areas Data Tape (2/85 version) [MRDF]. Pub. Order No. PB85-161115. Feb 1985. U.S. National Bureau of Standards [NBS] [producer]: Washington, D.C.; U.S. National Technical Information Service [NTIS] [distributor]: Springfield, Virginia. In Eng.
This data set consists of seven files containing various numbers of records of fixed, 132-character, logical record length. The files reflect the revised definitions of the U.S. metropolitan statistical areas announced in June 1983 by the Office of Management and Budget. According to these revisions, 257 Metropolitan Statistical Areas (MSAs), 23 Consolidated Metropolitan Statistical Areas (CMSAs), and 78 Primary Metropolitan Statistical Areas (PMSAs) are identified. "This tape contains computer files documenting titles, components and Federal Information Processing Standards (FIPS) codes for Metropolitan Statistical Areas and related statistical areas. It includes two computer files to convert titles, components, and FIPS codes for Standard Metropolitan Statistical Areas [the previous term] to June 30, 1983 MSA definitions."
