Die Story zum Datensatz:

The STATLAB Census covers 1296 member families of the Kaiser Foundation Health Plan (a prepaid medical care program) living in the San Francisco Bay Area during the years 1961 - 1972. These families were participating members of the Child Health and Development Study conceived and directed by Jacob Yerushalmy, for many years Professor of Biostatistics in the School of Public Health, University of California, Berkeley.

On her first visit to the Oakland hospital of the Health Plan after pregnancy was diagnosed, each woman was interviewed intensively on a wide range of medical and socioeconomic matters relating both to herself and to her husband. In addition, various physical and physiological measures were made. When her child was born, further data about her and her newborn baby were recorded. Approximately 10 years later the child and mother were called in for follow-up testing, interviewing, and measurement. In some instances, the husband was also interviewed and measured.

The 1296 families of the STATLAB Census are divided into two equal subpopulations: 648 families consisting of a mother, father, and female child; and 648 families of a mother, father, and male child. The children were all born in the Kaiser Foundation Hospital, Oakland, California, between 1 April 1961 and 15 April 1963. The Census does not cover any other children who may also have existed in these families.

Of the multitude of available data, 32 variables have been selected for the Census. The following 36 Census pages list each of these 32 variables for each of the 1296 families. The first 18 pages cover the families with girls; the second 18 pages cover the families with boys. Within each of these two sets of pages the families are listed in order of mother's age, with the youngest mothers first and the oldest last.

Legende

The 32 variables pertaining to each STATLAB family are grouped by CHILD, MOTHER, FATHER, FAMILY. Certain of the data were collected at the time of birth (1961 - 1963) and certain other data at the time of test (1971 - 1972), thus resulting in seven clusters of data. The description and codes (where relevant) for each of the variables for each of the seven clusters, starting at the left of the printout, are as follows.

CODE

The Census pages consist of printouts numbered in consecutive dice numbers, i.e., the Census pages are numbered 11, 12, 13, 14, 15, 16, 21, 22, ... , 65, 66). Similarly the 36 families listed on each page are designated in consecutive dice numbers from 11 to 66. The identification number (ID no.) for any given family consists of two pairs of dice numbers, the first pair indicating page and the second pair indicating family on the page. To select a family purely at random from the population of 1296, it is necessary to throw the pair of dice twice. If, for example, the first throw gives a red 2 und a green 6, this selects page 26. If the second throw gives a red 5 and a green 4, this selects family 54 on that page. Thus the ID number for this family is 26-54.
