Data and Research methodsThe World Values Survey (WVS) obtains data from nationally representative samples of thecitizens from over a hundred countries. Using individual responses from the most recent threewaves (1995-1998, 2000-2004, 2005-2009) of the WVS, we create various measures ofenvironmental concern, such as willingness to pay for environmental improvement, rankingenvironmental protection against economic growth, and personal environmental actions, among others. Our data is initially split among OECD and non-OECD countries, but ultimately thepurpose is to investigate each country’s changes over time.Using multi-level models, our goal is to observe how these quantities change by ourtraditional economic and demographic factors, such as age, sex, income, and education, as wellas their interactions. The additional contribution we make is to attempt to distinguish betweenage and cohort effects. With multiple waves of the WVS, we look to distinguish between the ageand cohort effects that are likely both present in the rise of environmental awareness.We are also interested in noting how major events in the life-course, such as having achild, influence attitudes toward the environment. The effects of pollution on can be substantial,particularly for children, so we can hypothesize that the impact of having children would be togenerate heightened environmental awareness. Additionally, significant gender differences havebeen found in the health impacts of pollution. Incorporating education and income variables, andtheir longitudinal changes, will reveal more about the changes over time in beliefs aboutenvironmental protection in one’s community and in the world.
