description: This special topic poll, conducted April 5-10, 2007, is part of a continuing series of monthly polls that solicit public opinion on the presidency and on a range of other political and social issues. The focus of this poll was environmental issues. Respondents were asked to rate the condition of the natural environment and to give their opinions about the biggest environmental problem the world faces today. Questions about weather patterns focused on whether the respondent thought the average temperature in the United States and in the world had increased over time, and whether they believed the earth's temperature had been increasing over the past 100 years. Respondent's opinions about global warming were collected and included information on how important global warming was to the respondent, how serious it was to them, how much could be done to reduce future global warming, how much could be done to reduce the effect of global warming on people and on the environment, and whether the federal government should do more to try to deal with global warming. Respondents of this poll were also asked a series of questions about national parks such as whether the respondent had ever visited a national park in the United States, whether the country's national parks were better compared to five years ago, whether they are well managed, and what respondents thought should have priority at national parks. Other questions asked whether respondents favored or opposed tax increases on electricity and gas, building cars that use less gas, building appliances that use less electricity, building homes and offices that use less energy for heating and cooling, and lowering the amount of greenhouse gases allowed into the air. Respondents were also asked who they trusted to do a better job, President Bush or the Congress, handling the overall environment, global warming, and the national parks. Demographic information includes respondent sex, age, race, income, marital status, religious preference, education level, type of residential area (e.g., urban or rural), political philosophy, political party affiliation, whether the respondent owed or rented their home, and whether there was any children under the age of 18 living at the respondent's home.
description: The data contain a weight variable (WEIGHT) that should be used in analyzing the data. The data were weighted using demographic information from the Census to adjust for sampling and nonsampling deviations from population values. Respondents customarily were classified into one of 48 cells based on age, race, sex, and education. Weights were assigned so the proportion in each of these 48 cells matched the actual population proportion according to the Census Bureau's most recent Current Population Survey.
description: Households were selected by random-digit dialing. Within households, the respondent selected was the adult living in the household who last had a birthday and who was home at the time of the interview.
