Objectives

The main aim of the survey is to operationalise and research the concept of Social Capital, and to translate the theoretical idea of Social Capital into magnitudes that allow for the following:

a) Determine whether they exist and the weight of the interrelations between underlying dimensions.

b) Establish comparisons between different geographical areas (zones-countries)

c) Act as input for models that aim to analyse relations between the Social Capital, its dimensions, health, well-being, economic development, etc.

d) Provides institutions with a tool that enables plans associated to the researched dimensions to be designed.

e) Perform economic estimates of the Social Capital in the Basque Country and its provinces and zones.

Sample design

- Sample design: There is a random sampling stratified in a single stage with allocation proportional to the province, size of the municipality and nationality, and balanced both by sex and age in the provinces and by regions of the Basque country.

- Sampling frame: Statistical Population Register (2016 Population Database) and 2016 Housing Directory.

- Sampling units: Population aged 15 and over living in dwellings and collective establishments in the Basque Country.

- Sampling size: 7,000 individuals.

- Stratification: A stratified sampling is performed across Provinces, Size of municipality: capitals, average (from 100,000 to 20,000) and small (20,000 or less) and by Nationality: Spanish and others.

- Allocation: A distribution is carried out proportional to the square root of the number of individuals per province, proportional to the number of individuals by size of municipality and proportional to the 2/3 power of the number of individuals by nationality.

- Extraction procedure: Simple random sampling in the stratum. The Cube Method (Deville & Tillé, 2004) was used, which allows for balanced sampling while maintaining the proportions of the original population in the sample in balancing variables, taking into account the design's inclusion probabilities. The balancing variables are the population in the (20) regions and also the population distribution by age and sex in the provinces. This method allows a sample to be obtained that responds to the allocation made for the strata (Province, Size of municipality and Nationality) and it is also balanced for the population in the (20) regions as well as for population distribution by age and sex in the provinces.

9) Extracted variables: Name and surname, date of birth, sex, nationality, postal address of the dwelling and, if not the owner of the dwelling, the name and surname of the owner.

- Procedures: Extract the individuals from the Population Database sample, search for their household in the Housing Directory and assign the owner of the household.
