Dataset: Norwegian Election Study time series, 2001-2009


Two time series are constructed, one for surveys 1977-1997 (NSD1760-1) and one for the 2001-2009 surveys. These files are repeated variables combined. This makes it possible to analyze changes in motivation for participation and the choice of political parties over time. This can provide valuable information on voter attitudes and how political preferences have changed over the last 30 years.

Series Information

The Norwegian Election Research Programme was launched in the middle of the 1950's, under the direction of The Institute for Social Research. Henry Valen and Stein Rokkan were responsible for the programme. The programme co-operated with Norsk Gallup Institute A/S for sample survey data collection in the election studies covering the Storting elections in 1957, 1965, 1969 and 1973. Since 1977 the programme has co-operated with Statistics Norway (SSB) for the data collection for these studies. The election studies are intended to give statistical data for research covering elections and political processes in Norway. Since the start of the Norwegian Election Programme Professor Henry Valen has been the key administrator, but in 1985 Bernt Aardal took over as executive manager.

Sampling Procedure

The survey sample was divided in two groups. One group was a panel consisted of almost 1500 respondents that also had been interviewed in the previous Election Study. The second group was cross sectional, around 1500 respondents were drawn randomly. These will contitute the panel for the next election.  

The sample is a so-called rotating panel, meaning that half of the respondents in one survey also were interviewed in previous study, and that these respondents were also contacted in the next.

The sample was drawn using Statistics Norway's standard sampling frame for face-to face interviews, which uses random sampling in two stages. The standard sampling frame firstly divides the country into a number of primary sampling areas, which in turn are divided into 109 subpopulations, called strata. The criteria for stratification of primary sampling areas are economic classification, population density and centrality. The aim is to create strata, which are as homogenous as possible, but still geographically concentrated. The primary sampling units are municipalities or aggregates of municipalities. Municipalities with few inhabitants are grouped together with other municipalities to ensure that each sampling area consists of at least 7 per cent of the total number of inhabitants in the stratum the municipality belongs to. All municipalities with more than 30 000 inhabitants and some with 25 000 to 30 000 inhabitants constitute separate strata. The other sampling areas are stratified, within each county, by industrial structure, population density, centrality, patterns of commute and trade, media coverage and communications.
