This data collection is part of a continuing series of semi-monthly surveys of individuals in Spain. Each survey consists of three sections. The first section collects information on respondents' attitudes regarding personal and national issues. This section includes questions on level of life satisfaction and frequency of relationships, as well as a rating of the importance of national issues. The second section varies according to the monthly topic, with this month's topic focusing on ecology and the environment. Among the issues investigated are the size, population, and climate of the respondent's ideal place of residence, and the respondent's attitudes toward population issues, the depletion of natural resources in Spain and around the world, the earth's environmental problems, the relative importance of environmental problems versus social problems and overpopulation, the promotion of economic development versus environmental protection, possible solutions to environmental problems and who should be responsible for their implementation, and potential measures to protect the environment. Also included is information on the respondent's level of participation in recycling programs and efforts to buy ecologically safe packaging and organically-produced foods. The third section collects demographic data such as sex, age, religion, income, and place of residence.
