Indagine sul Pregiudizio Regionale ed Etnico, Italia, 1994

Summary

The 1994 Survey on Regional and Ethnic Prejudice in Italy was designed to assess the attitudes of Italians toward recent immigrants from Africa and Eastern Europe, and to measure the current state of relations between Northern and Southern Italians. It also included many items on politics and society. The study was conducted in a key period of Italian history after the collapse of political parties in the postwar system.

Data Collection Notes

  1. The underlying data is exactly the same in the English and Italian versions. The only difference between them are that eight variables are named differently. These variables are listed in the processing notes at the beginning of each ICPSR codebook. Otherwise all variable and value labels, formats, missing value designations should be equivalent after translation.

  2. ICPSR has written processing notes that can be found at the beginning of each ICPSR codebook. Through the use of Google translate ICPSR has translated the notes from English into Italian for dataset 2 (Italian Version). The remainder of Italian language used in the data files (variable and value labels), question text, and appendices in the P.I. codebook for dataset 2 has come from the Principal Investigators. In these instances, ICPSR did not alter or confirm the equivalency between Italian and English.

  3. The survey asked respondents to describe their current or last job (A13), their father's (A16) and mother's (A17) occupation when s(he) was 14, and their spouse's occupation (A18) (if married). The Principal Investigators classified these open-ended responses into 93 categories. However, out of a desire to protect respondent confidentiality, due to low counts in some occupational codes, value labels were not provided by the Principal Investigators for these variables. But they did categorize these 93 codes down into eight categories. This second level of categorization created the variables in English/Italian as (ROCC/PROFINT), (FOCC/PROFPAT), (MOCC/PROFMAT), and (SPOC/PROFCON).

    The Principal Investigators later decided to provide pages from a book authored by one of them that contains the description of these 93 occupational codes. This document, in Italian only, is available as a restricted-use file. Any interested researcher wanting to obtain this file will need to apply for access to it through ICPSR's restricted-data access system.

Study Purpose

Purpose of this study was to:

  • assess the attitudes of Italians toward recent immigrants from Africa and Eastern Europe;
  • measure the current state of relations between Northern and Southern Italians.

Study Design

The survey was a nationwide telephone survey carried out under the auspices of the Faculty of Sociology at the University of Trent, Italy, with technical assistance from the Survey Research Center of the University of California, Berkeley.

This was one of a series of studies focusing primarily on racial attitudes, politics, and prejudice carried out under the lead of Paul M. Sniderman of Stanford University and Thomas Piazza of the University of California, Berkeley. These studies were designed to incorporate several experiments into computer-assisted surveys. The computer randomly asked certain questions of some respondents and not others, or questions were asked of everyone but in a different way. Explanation of which variables and how they were effected are detailed at the beginning of several sections in the P.I. Codebook.

Sample

This study utilized a stratified random sample of all telephone numbers in Italy. The database of current residential telephone numbers was divided into separate strata for each of the 20 regions, and each region was divided into 5 strata based on the population of the town or city. Within each of the resulting strata, a random sample of 1/2,250 of the telephone numbers was drawn. This procedure was carried out by the Milano List Service. The resulting sample contained about 12,200 telephone numbers.

The sample received from Milano List Service was divided into random subsamples, to be used as needed to obtain approximately 2,500 interviews. The first subsample of 3,052 telephone numbers was created by systematic random sampling: after a random start, every fourth telephone number in the large sample was selected. This systematic sampling ensured that the stratification by region and size of place would be preserved in the main subsample used for interviewing. A second subsample of 3,052 telephone numbers was drawn from the large sample in the same way; this subsample was then put into a random order, to be used as need for the fieldwork.

Within each selected home, one person aged 18-69 was selected at random for interviewing. Each eligible adult was first listed, and then a computer-generated random number was applied to the list to designate one of the persons as the respondent. No substitutions were allowed, and repeated callbacks were made in order to complete the interview with the selected person.

Mode of Data Collection

Description of Variables

Each data file contains 182 total variables. Outside of those sections for administrative and demographic variables almost all of the remaining variables are patterned after Likert-type response options (4- or 5-category agreement, willingness, importance, or happiness scales).

Response Rates

Of 6,007 selected telephone numbers, 4,558 were deemed eligible Italian households after several calls. Of the eligible households, 2,001 (43.9 percent) resulted in a completed telephone interview. Please see Appendix C of the P.I. Codebook for additional details regarding the response rate.

Version History

2022-08-22 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Created online analysis version with question text.

Weight

A person-level sampling weight (SAMPWT) is provided, which adjusts for differences in the probablility of selection due to the number of eligible persons in each selected household. The relative sampling weight is the number of eligibles (up to a maximum of 5). A post-stratification weight (PSWT) adjusts further for gender by region, to match the 1991 Census. Please see Appendix B of the P.I. Codebook for additional details on the creation of the weights variables.
