The institute Stack Data Strategy carried out sample surveys in February 2024 at the request and on behalf of Focus 2030.
Sample sizes :
- 1,496 adults were surveyed between 16 and 21 February 2024 in France.
- 1,534 adults were surveyed between 16 and 22 February 2024 in Germany.
- 1,499 adults were surveyed between 16 and 21 February 2024 in Italy.
The surveys were administered online. Each of the samples selected was weighted using the quota method to represent the adult population in terms of age, gender, region, level of education and vote in the last national elections, respectively in the three countries surveyed (France, Italy and Germany).
Due to weighting and rounding, the percentages shown in the data tables do not always add up to 100%.
Given the size of this survey, when interpreting these results it is prudent to use a margin of error of 2.5% at the 95% confidence level. The margin of error decreases when the statistic in question is closer to 0% or 100%.
