The 2014 Social Change Impact Report was conducted online by Harris Poll on behalf of Walden University between June 1 and 17, 2014, among a total of 9,138 adults within Brazil (1,009 adults ages 18–64), Canada (1,003 adults ages 18–64), China (1,021 adults ages 18–64), Germany (1,000 adults ages 18–64), India (1,021 adults ages 18–64), Jordan (1,027 adults ages 18 and older), Mexico (1,020 adults ages 18–64), and U.S. (2,037 adults age 18 and older). Data for each country were weighted to the general or online population within each country.
Details on data collection and the weighting of data for each country are provided below.
|Country||Sample||Language Survey Conducted||Population Represented||Variables Adjested Where Necessary by Weighting|
|Brazil||1,009 adults ages 18–64||Brazilian Portuguese||Online||Age, gender, region, household income|
|Canada||1,003 adults ages 18–64||British English/
|General||Age, gender, region, education, household income, race|
|China||1,021 adults ages 18–64||Simplified Chinese||Online||Age, gender, region|
|Germany||1,000 adults ages 18–64||German||General||Age by gender, region, education, Internet usage|
|India||1,021 adults ages 18–64||British English||Online||Age, gender, household income, hours online per week, bought online in past month|
|Jordan||1,027 adults ages 18 and older||Arabic||Online||Age, gender|
|Mexico||1,020 adults ages 18 and older||Latin American Spanish||Online||Age, gender, region, social grade, education|
|United States||2,037 adults ages 18 and older||American English||General||Age, gender, region, race/ethnicity, education, household income|
Data for each individual country is representative of that country. The “Average Result” is the arithmetic average across the countries. This measure does not account for differences in population size and thus is not representative.
All sample surveys and polls, whether or not they use probability sampling, are subject to multiple sources of error which are most often not possible to quantify or estimate, including sampling error, coverage error, error associated with nonresponse, error associated with question wording and response options, and post-survey weighting and adjustments. Therefore, Harris Poll avoids the words “margin of error” as they are misleading. All that can be calculated are different possible sampling errors with different probabilities for pure, unweighted, random samples with 100% response rates. These are only theoretical because no published polls come close to this ideal.
Respondents for this survey were selected from among those who have agreed to participate in Harris Poll surveys. The data have been weighted to reflect the composition of the adult populations of the respective countries. Because the sample is based on those who agreed to participate in Harris Poll panel, no estimates of theoretical sampling error can be calculated.
