Dataset: Generations and Gender Survey Norway Wave 1

Abstract

The Generations and Gender Survey (GGS) provides micro-level data with the aim of significantly improving the knowledge base for social science and policymaking in Europe and developed countries elsewhere.  
In Europe 2020, the European Union develops a strategy "to help us come out stronger from the crisis and turn the EU into a smart, sustainable and inclusive economy delivering high levels of employment, productivity and social cohesion". The economic crisis affects not only day-to-day decisions, but also fundamental choices at all stages of people's lives:  marriage and childbearing, the combination of employment and caring responsibilities for the young and the old, retirement, housing, and ageing well. The GGS has been developed to provide scientists with high-quality data to contribute scientifically grounded answers to these key policy questions. Survey content focuses on intergenerational and gender relations between people, expressed in care arrangements and the organization of paid and unpaid work. Key feature of the survey are:  
- Cross-national comparability. In each country data is collected on the basis of a common international questionnaire and guidelines about the methodology. Data processing includes central harmonization of national datasets.  
- A broad age range. It includes respondents between the ages of 18 and 80.
- A longitudinal design. It has a panel design, collecting information on the same persons at three-year intervals.  
- A large sample size. It has an average of 9,000 respondents per country at Wave 1.
- A theory-driven and multidisciplinary questionnaire. It provides data for policy relevant research by demographers, economists, sociologists, social policy researchers, social psychologists and epidemiologists. The questionnaire is inspired by the theory of planned behavior.
- Possibility to combine the survey data with macro data provided by the GGP Contextual Database. This combination enables analyses of individuals and families in their cultural, economic, political, social and policy contexts.

Guide To Codebook

In the field “Study Description”, users can find metadata about surveys. This includes the distributors, keywords, abstract, and guidelines on the bibliographic citation.  
Country specific metadata include information on survey producers, methodology and processing. This information was provided by the GGP-country teams, based on a metadata grid with pre-structured questions. Links to relevant references (e.g., working papers and questionnaires) are also provided.  

The field “Data Files Description” provides metadata about the data file, such as file contents, missing values, as well as changes across different GGS versions.

The field "Variable Description" provides information on each variable, such as question text, descriptions of country specific categories and variables, universe (i.e., subset of respondents to whom the question was asked), country specific deviations to GGS routing, descriptions of the ways in which consolidated and derived variables are calculated. Variables are ordered according to the sections of the GGS codebook.

PLEASE NOTICE THAT WE DOCUMENT ONLY VARIABLES HAVING VALID CASES.  
VARIABLES HAVING ALL SYSTEM MISSING CASES ARE NOT DOCUMENTED.  
This is the reason why the total no. of variables in the documentation is smaller than the total number of variables in the SPSS and STATA files.

Type of Research Instrument

Structured questionnaire in Norwegian.

Characteristics of Data Collection Situation

1. Interviewers
1.1 Total number of interviewers: 223.
1.2 Number of interviewers in the field: 1-223.
1.3 Network organization: Centralized.
1.4 Working arrangement of interviewers: Part-time.
1.5 Payment of interviewers: Per hour.

2. Interviewer training:  
2.1 General interviewing: Yes, general interview techniques, CATI and general knowledge on surveys carried out by Statistics Norway survey department.
2.2 Survey specific: Outline of the purpose of the study, the questionnaire, handling of sensitive questions and contact strategies.
2.3 Length: One day specific training for the interview. All recruited interviewers were experienced and trained interviewers of Statistics Norway survey department.
2.4 Control of performance: No.
2.5 Interviewer survey: No.

3. Contact protocols
3.1 Advance letter: Yes, each individual selected in the sample received an advanced letter introducing the survey and announcing the telephone call of an interviewer and the reason for his/her call, the survey subject, the agencies involved in the survey, the size of the survey. The letter included also information about the use of additional register data to facilitate the data collection and to reduce the interview time. The selected individuals were also invited to take contact if he/she had questions respective to the survey (free telephone number or by e-mail) or data privacy (contact information of the data protection officer). The letter included also a leaflet with information about the survey and two scale cards that could be used during the interview. Some of the information in the letter was adapted to the age of the selected individuals and if they were part of an earlier survey or not.
3.2 Cold contacts: Telephone.
3.3 Scheduling / scattering: Yes. To get the highest response rate, contact attempts were scattered over different days of the week and different parts of the day.
3.4 Contact history: Yes. For each contact attempt the interviewer had to report the date, the time and the outcome grid.
3.5 Min number of contacts: No.
2.6 Max number of contacts: No.

4. Questionnaire localization
4.1 Validation: No.
4.2 Pre-test: Two rounds with in-depth qualitative interviews (in total 19 interviews) using different parts of the questionnaire and different versions of the announcing letter were carried out in June and August 2006. A pilot of the telephone interview was carried out in December 2006 (150 respondents).
4.3 Length of interview: The average duration of interview was 43 minutes, with a large variance according to the composition of the household and the complexity of the family structure and history of the respondent.

Actions to Minimize Losses

1.  Dealing with nonresponse
1.1 Screening: No.
1.2 Refusal conversion: No special methods - usual techniques of refusal avoidance, i.e. specify that personal information will remain confidential, offer to call for changing the time of interview, insistence of the research purpose.
1.3 Incentives: Yes. Among those completing both the telephone interview and sending back the self-administered postal interview, 7 individuals were drawn to win a gift voucher amounting to 10,000 NOK (approximately 1,250 Euro).

2. Tracking of sampled units
2.1 Respondent contact information: No.
2.2 Other contact information: No.
2.3 Cards: No.
2.4 Additional surveys: For a part of the panel sample the GGS is the second round. 7,861 individuals aged 40 years or older in 2002, participated already in 2002/03 in the "Norwegian Live Course Ageing and Generation Study", a quantitative survey, based on computer assisted telephone interviews on topics as ageing, health, work and retirement, familiy relations in the second half of the life and well-being.
2.5 Administrative records: Yes, whole sample is based on administrative records.

Control operations

Automatically consistency checks through the CATI system during the interview.

Weighting

A weighting variable (aweight_2001) at the respondent level was built to reduce any non-response bias. The sample has been weighted according to the net sample. The variables used in the weights are sex, age, geographical region, centrality and education. The largest bias is related to education: those with primary education are somewhat underrepresented in the Norwegian GGS (5.5% difference between gross and net sample), whereas persons with college or university education are somewhat overrepresented (6.5% difference between gross and net sample).
The other weighting variable (aweight) is a standardized weight based on country specific population weight and it is recommended for use.

Cleaning Operations

The datafile was checked and anonymized by Statistics Norway / NOVA before being sent to data harmonization.

Response Rate

Response rate - Final disposition codes:
I = complete interview: 15,114
P = partial interview: 42
NE = non-eligible: 479 respondents not interviewed due to death, emigration or institution, 264 respondents sorted out due to age limit (aged 80 years or older), 11 respondents sorted out due to anonymisation.
NC = non-contact: 2,186
R = refusal: 6,705
O = other non-response: 1,047
UC = unknown eligibility, contacted DK
UC = unknown eligibility, non-contact: DK
eC = estimated proportion of contacted cases of unknown eligibility that are eligible: DK
eN = estimated proportion of non-contacted cases of unknown eligibility that are eligible: DK

Completeness of Study Stored

The GGS core questionnaire was adapted to fit with the Norwegian context and because of time and budget constraints some questions were dropped of modified. Other questions - belonging to the second wave of the "Norwegian Life Course Ageing and Generation Study" - were added. The added questions are not part of the GGS harmonized data file.

Contents of Files

VARIABLES HAVING ALL SYSTEM MISSING CASES ARE DROPPED BEFORE PUBLICATION IN NESSTAR.
This is the reason why the total no. of variables in the Nesstar data file is smaller than the total number of variables in the SPSS and STATA files.

Variables are ordered according to the sections of the GGS codebook: Household, Children, Partnerships, Household Organisation and Partnership Quality, Parents and Parental Home, Fertility, Health and Well-Being, Respondent's Activity and Income, Partner's Activity and Income, Household Possessions, Income and Transfers, Value Orientations and Attitudes, Interviewers' report.
The variables begin with a letter designating the wave of data collection ("a" for the first wave likewise "b" for the second wave). We have attempted to keep the names of variables the same across the waves, and all the new variables would be identified as follows ["wave letter"]n e.g.  bn301.  
Although we encourage the countries to strictly follow the GGS Questionnaire, countries might implement a question that differs to a considerable extent from the GGS Questionnaire. In this case either we add country specific response values, or we introduce a country specific variable.  
Country specific values are added when the question follows the model questionnaire, but the answers are not at all or partly compatible. They are at least 4 digits long (F4 format) and begin with the country code: e.g., Australia 2401. Hence, the country code, as an example, for Australia is 24.  
A country specific variable is introduced when the question differs from the model questionnaire albeit measuring the same concept. This kind of variables is identified with a suffix given by the country code plus a number, e.g., Australia a119_2401.
In order to have an overview of GGS country code, please refer to the variable "acountry".

Extent of Processing Checks

DATA HARMONISATION
The data is submitted in an already pre-harmonised form. It is prepared and organised according to the GGS standards.  
Harmonisation aims at achieving a clear and comparable format of the GGS micro-data files that would be adequate for cross-country comparison.  The harmonisation procedure basically is composed of:
1. Label checks  
This step makes sure that all the variables are named the same across the countries and refer to a particular question in the GGS Questionnaire. Also the value labels are checked. They should be the same across GGS datasets.  
2. Dealing with grids
The GGS Questionnaire holds several grids of either event history information or members of the household. Such data needs to be harmonized with specific attention to order and logical consistency of grid-rows (be either household members or events such as births). In data sense each row of the grid is represented by variable name followed by a subscripted number ("_#"). Each subscript thus represents one household member or one event. Part of the grid harmonization is grid sorting. Grid rows are sorted according to pre-defined key. For example in the household grid, the household members are sorted according to their relationship to the respondent i.e. the relation to respondent variable (ahg3_# or bhg3_# ). Respondents would appear, first, followed by their partners and children if any and then followed by other household members. As there may be more then one child (or other relative) living in the household they also would need to be sorted. In the case of the household grid, age is used as the secondary sorting key (starting with the oldest person to the youngest).
3. Routing
Routing check ensures that the structure of underlying data set matches the structure of the GGS questionnaire. Its main goal is to code any given variable in the dataset to either a valid response, nonresponse or skip as indicated in the questionnaire. Consequently, the indicated skip in the quetionnaire is represented with a system missing code (. in STATA, sysmis in SPSS), while the missing information for other reasons is coded into non-applicable/no response (i.e. codes 7, 8, 9 in SPSS or .a, .b, .c in STATA).  
4. Consolidation  
The process consolidates the information scattered over several variables into a single one. The consolidation procedure is carried out in the Children Section, the Partnership Section and the Parents and Parental Home Section.
5. Imputation  
Due to its sensitive nature, the respondents are reluctant to share income information with the interviewer. In order to be able to use income information in a cross country comparative study and not to loose too many observations in the process it is necessary to impute the approximately correct distribution of the income variable in each country.  
6. Calculation of derived variables
We calculate derived variables out of the following variables:
- grid variables (i.e., household grid, children grid, and partnership history grid); the codebook starts with the constructed variables that sum the key socio-demographic characteristics of the respondent.
- month and year variables,  
- hours and minutes variables,
- frequency and unit variables.  
Occupation variables are recoded into ISCO-88 1 digit.
Explanations of the ways in which consolidated and derived variables are obtained, are available under the field "Note" of the "Variable Description" sections.
For a more detailed and technical procedure please refer to the Data Cleaning and Harmonisation Guidelines.

Missing Data

The following missing values have been assigned:
- 6, 96, 996, etc. = Unknown (only for consolidated variables in the group "administrative variables")
- 7, 97, 997, etc. = Don't know
- 8, 98, 998, etc. = Refusal
- 9, 99, 999, etc. = Not-applicable/no response

- Variables which have now country specific values: a203c_*
- Variables now available: a344y (now available also for widows/widowers).

IMPROVEMENTS INTRODUCED WITH V.4.0 (March 2010)
The individual income variables of the Respondent a866_* and the partner a938_* have been renamed  into country specific variables a866_*_2000 and a938_*_2000, respectively. There are two deviations from the GGS Core Questionnaire for these variables. They are first, the annual and second, the gross amounts of payments for each income  type.  
For the Respondent (not the partner!) another country specific variable has been made available: a866_2000. This  "after-tax income" is calculated as the sum of wages and salaries, income from self-employment, property income and  transfers received minus total assessed taxes and negative transfers.
