Survey research is rapidly moving online – it’s cheaper, faster, provides greater flexibility in questionnaire design, and often has substantial advantages in data quality compared with phone surveys. Web surveys are being adopted in all sectors of the industry, from marketing to the U.S. Census Bureau’s American Community Survey to election polling.
That makes it increasingly important to assess the accuracy of these surveys. Surveys that include only those who use the internet (and are willing to take surveys online) run the risk of producing biased results. And, in fact, a notable share of Americans either cannot or will not complete a survey via the internet.
That raises two questions: Whom do you miss with a Web-only survey, and how does it affect your results?
In this instance, there was a way to get at the answers by turning to our American Trends Panel, a nationally representative group of Americans who have agreed to participate in our surveys. Most of the panel members participate via the Web, but a sizable number (representing nearly one-fifth of the public) do not. A little more than half of these non-Web participants are not online, and the rest would not provide an email address in order to be surveyed. However, we are able to survey the non-Web panel members by mail and assess how much, if at all, their non-participation would affect the outcome in a national poll conducted exclusively online.
Chinese President Xi Jinping’s tour of the United States comes at a time of many tensions between the two nations. Experts believe China was behind the recent cyberattack against the Office of Personnel Management. America’s Asian allies are worried about Beijing’s aggressive posture in the South China Sea. Human rights groups warn that Xi’s tenure in office has coincided with a harsh crackdown on public dissent, such as a recent incident involving rights defense lawyers and another involving women’s rights activists. And Donald Trump and his competitors have made the economic challenge from China a major issue in the Republican presidential primary contest.
As Pew Research Center surveys have shown, many of these tensions are reflected in American public opinion. Meanwhile, the Chinese public has its own complaints about the U.S. – in particular, most believe the U.S. is trying to contain a rising China.
Here are six key findings about American public opinion toward China, and Chinese public opinion about the U.S. Read More →
Issues of economic inequality have pushed their way back into the national and global conversation – from Pope Francis and Sen. Bernie Sanders to Thomas Piketty and ongoing debates about raising the minimum wage. Surveys, though, show a wide partisan gap in views of whether inequality is a problem that should be addressed. For instance, an NBC News/Wall Street Journal poll in January found that, while 67% of Democrats identified reducing income inequality as an “absolute priority,” just 19% of Republicans did.
And economists are also divided on just how to define and measure inequality. As Federal Reserve economist Arthur Kennickell wrote in a 2009 paper, “‘Inequality’ may seem a simple term, but operationally it may mean many different things, depending on the point of view.” Most researchers agree that wealth is more unevenly distributed than income, while consumption is less concentrated at the upper end than either wealth or income.
The most-cited measures of inequality involve income. In a recent report, for instance, the Organization for Economic Cooperation and Development noted that “in OECD countries, the richest 10% of the population earn 9.6 times the income of the poorest 10%.”
The U.S. Census Bureau publishes two measures of income inequality each year. According to the most recent report, the top 5% of households received 21.8% of “equivalence-adjusted” aggregate income in 2014, while the bottom 60% received just 27.1%. (Equivalence-adjusted estimates factor in different household sizes and compositions.) Read More →
When Pope Francis – the first Latin American pontiff – arrives in the U.S., he will find a Catholic public that increasingly has roots in Latin America, as Latinos now make up 34% of all American Catholic adults.
But what may be less commonly known is the divide between Latino and white American Catholics on some church teachings. On a variety of issues – such as recognizing gay marriages and determining eligibility for Holy Communion – Latino Catholics tend to be more aligned with the church than are white Catholics, according to a new Pew Research Center survey. And Latino Catholics are more likely than white Catholics to view a variety of behaviors as sins.
For example, while majorities of white Catholics believe the Catholic Church should allow those who are living with a romantic partner without being married (69%) or who have divorced and remarried without an annulment (74%) to receive Communion, roughly half of Latino Catholics say the same (49% and 44%, respectively).

On his first papal trip to the U.S., Pope Francis will visit three Northeastern cities that are within a few hundred miles of each other. But while New York City, Philadelphia and Washington, D.C., may be geographically close, their Catholic populations look different from one another in several ways, according to data from the 2014 Religious Landscape Study.
For instance, 85% of Catholics in the Philadelphia metropolitan area are non-Hispanic whites. Whites, however, make up smaller shares of the Catholic populations in New York (57%) and Washington (50%).
From a racial and ethnic perspective, Catholics in the NYC metro area look very similar to U.S. Catholics overall, including about a third who are Hispanic. Fewer D.C.-area Catholics are Hispanic (23%), while more in the capital are black (15%) or Asian (10%) compared with the country overall.
One year after history-making political change swept the country, Indians’ fervor for their leader Narendra Modi has not abated. A new poll in India shows the public’s views of the country’s direction and the economy are on the rise.
Even so, Indians continue to see problems in their daily lives and in foreign relations. Nevertheless, in advance of Modi’s visit to the United States later this month, Indians are confident in relations between the two countries. Here are some of the key findings from a new Pew Research Center report:

In a recent survey of what Americans know about science, we asked people to interpret the chart you see here and tell us what it showed. Six-in-ten (63%) identify the best interpretation of this chart as “the more sugar people eat, the more likely they are to get cavities.”
This kind of chart — known as a scatterplot — is very familiar to people who are used to working with numbers, such as economists, scientists, researchers and data journalists. It is a good way to show a relationship between two variables.
Even before Donald Trump and Ben Carson roiled the GOP presidential race by surging past more traditional candidates in the polls, the nation’s Republicans were a restive bunch. Over several surveys, many expressed disapproval of their own party and leaders even after Republicans captured both houses of Congress in the 2014 midterm elections.
One undercurrent in recent surveys – and a theme of the campaign itself – is the negative sentiment many hold for the political establishment. Seven of the 16 GOP presidential candidates are either sitting senators or have held office in Washington. But many of them are running as anti-Washington candidates, and others have battled party leaders, such as Texas Sen. Ted Cruz; he made headlines by taking on his own party’s leader on the Senate floor.
Sub-Saharan Africans are feeling positive about their current and long-term economic prospects compared with people in other regions of the world. However, Africans still see the need for more foreign aid and are concerned about the serious challenges facing them, especially when it comes to better health care and jobs.
This new snapshot of public opinion in nine African nations comes at a time when the United Nations is preparing to ratify new global goals that will shape the development agenda in Africa and elsewhere for the next 15 years. Africans’ views of their region’s development also come at a time when the U.S. and China are competing to be major players in Africa. Most in the region express favorable views of both countries – in fact, the U.S. and China are viewed more positively in Africa than in any other part of the world.
Here are some key findings from the 2015 survey of nine African nations:
1Although there is a pervasive gloominess about the state of the economy throughout much of the world, Africans are relatively positive about their short- and long-term economic future. Across the nine African nations polled, a median of 60% say they expect their country’s economy to improve over the next 12 months, the highest of any region. A median of 56% believe children in their country today will be financially better off than their parents, and about seven-in-ten or more hold this view in Nigeria, Ethiopia and Burkina Faso.

There is a significant gap in knowledge about scientific concepts along racial and ethnic lines in the U.S., according to a new Pew Research Center report released last week.
When asked a series of 12 science-related questions, whites, on average, fared better than blacks or Hispanics. While the average number of questions whites answer correctly is 8.4, for Hispanics that number is lower – 7.1 – and drops to 5.9 for blacks. (There were not enough Asian respondents in the sample to be broken out into a separate analysis.)
Our latest findings are consistent with previous Pew Research surveys and with data from the General Social Survey (GSS) conducted by the National Opinion Research Center. These differences tend to span multiple scientific disciplines, from life and earth sciences to physics and energy-related questions.
But why is this? Research suggests there might be several factors at play, and they often are interconnected. Educational attainment – such as the different shares of blacks and whites to have college degrees – may be one. Another issue might relate to the underrepresentation of blacks and Hispanics in the STEM (science, technology, engineering and mathematics) workforce. And access to science information may also play a role in how well people cultivate an understanding of the subject.
