FAQs on maps depicting Ireland's beliefs, attitudes, and policy preferences about climate change

  • What do these maps depict?

    The maps depict estimates of the percentage of adult residents of Ireland (age 18 and over) who hold particular beliefs, attitudes, and policy preferences about climate change. The estimates were generated from a statistical model that incorporates actual survey responses but combines these responses with demographic data from the Ireland Central Statistics Office (CSO) (Census 2016 Reports - CSO - Central Statistics Office) to estimate opinions for different groups of people based on information such as their gender, age, and county of residence.

  • Where do the survey data underlying the estimates come from?

    The data underlying the maps come from a large national survey dataset (4,000 respondents) collected during May through July of 2021 as part of a collaboration between the Irish Environmental Protection Agency (EPA) and the Yale Program on Climate Change Communication (YPCCC). Reports using the individual-level survey data are available here:


  • What does the grey colour mean on some of the bars beneath the maps?

    The grey area reflects people who provided valid responses such as refusal to answer a question, saying they “Don’t know,” or gave an answer that was not modeled (e.g., “Currently doing the right amount”). We do not provide specific values for the grey areas because we did not develop estimates for these particular responses.

  • Do the maps account for differences in population density across the country?

    The type of map used in this tool is called a choropleth map, which means the colours on the maps reflect the percentage of the population in a given geographic unit who would answer each question as indicated. These kinds of maps are used to represent everything from election results to census and economic data (e.g., per capita income or unemployment rates). Thus, it is important to keep in mind that some geographic areas may be large, but have few residents (e.g., Mayo), while other geographic areas may be small, but have many residents (e.g., Dublin). For reference, The Central Statistics Office has published the relevant population density information.

  • Do these maps reflect changes in opinions due to recent extreme weather events like Storm Ophelia/Storm Barra?

    Perhaps. The maps may reflect the impacts that specific extreme weather events had on public opinion in a given geographic unit. If public opinion in a particular area has been influenced by local events it is possible that the model would detect such an influence. However, data from specific events or types of events are not explicitly built into the model as predictor variables.
