Temple University history professor Jessica Roney shares insights about America's Founding Fathers and illuminates the lesser-known history behind the formation of the United States.

Mangrove forests are natural protectors, shielding coasts from storms, sheltering species, and soaking up carbon. Reversing the decline of these habitats isn't just a science—it's an art, says marine biologist Octavio Aburto. He uses his camera along with high-resolution satellite imagery to assess real-time changes in mangrove coverage—and to reveal the amazing hidden marine life of these critical ecosystems.

Stat: 93. The Food and Agriculture Organization of the U.N. estimates 93 percent of marine fisheries worldwide are fished at or beyond sustainable catch levels. Story: A large part of overfishing is driven by subsidies—most of which go to large-scale fishing fleets from industrialized nations. We learn about how subsidies can alter the economics of fishing from Pew's Isabel Jarrett and researcher Rashid Sumaila. And we travel to Senegal to hear from local fishers on the impact to their communities.

Stat: 46. The percentage of American adults who worry that they will not be able to live comfortably in retirement. Story: After all the hard work and child rearing, do Americans get to finally relax and retire with some financial stability? Research shows the golden age of retirement doesn't always shine.

Stat: $233,610. The cost of raising a child through age 17 for a middle-class American family, not including a college education. Story: From diapers to day care and beyond, it's getting more expensive to raise a family in the U.S. And just keeping up with daily costs makes saving for a rainy day or retirement all the harder. We speak with three families about what it takes to make it work—and what keeps them up at night.

Stat: 86. The percentage of women ages 40-44 who are mothers, compared with 80 percent in 2006, according to a Pew Research Center analysis. Story: American women are waiting longer to have children—but are more likely to have kids than they were a decade ago. Also, 1 in 4 parents living with a child is not married. In this episode, a Pew researcher explains the data behind this change in the American family, and we meet two moms who share why they waited.

Stat: 7. On average, Americans are waiting nearly seven years longer to get married than they did in 1968, according to the U.S. Census Bureau. Story: Does putting off marriage mean people no longer want to say "I do?"

Marriage historian Stephanie Coontz also offers insights.

Story: The American family is changing. We explore how over the next four episodes, taking you into the lives of American families through conversations at kitchen tables, in workplaces, and even in the family car on the way to after-school pickup. Host Dan LeDuc also speaks with researchers about the data and trends on these informative and inspiring stories.

Stat: 20 percent. The share of Americans who find the concept of machines doing most human jobs in the future extremely realistic. Story: Will robots take our jobs? They'll need a key human skill first—the ability to think. To find out just how near such a future is, we visited Ashley J. Llorens, chief of the Intelligent Systems Center at the Johns Hopkins University Applied Physics Laboratory. There, researchers are bridging the gap between machines programmed by humans and those that can teach themselves.

Stat: 48%—Almost half the members of Generation Z—age 22 or younger—are racial or ethnic minorities. Story: Step aside, Millennials. There's a new, younger group out there: Generation Z, which includes anyone born after 1996. To learn more about this generation, we sat down with Kim Parker, director of social trends research at the Pew Research Center.

Stat: 844 million. The amount of people worldwide who lack even a basic drinking-water service, according to the World Health Organization. Story: For many of us, it can be easy to take water for granted. Turn on the tap and it's there. But today, the world faces a tipping point, with water security—having sufficient access to safe water for our daily lives—at risk. Listen in as our guest, Sandra Postel, discusses the challenges and shares options for fixing our broken water cycle.

Stat: 40%—Across Africa, the number of giraffes has declined by 40 percent since 1979. Story: Giraffes are dying, and experts are trying to figure out why. Host Dan LeDuc speaks to two giraffe experts, ecologist David O'Connor and researcher Jenna Stacy-Dawes of the San Diego Zoo, who are trying to learn more about these mysterious animals and help giraffes rebound.

Stat: 1919—the year President Woodrow Wilson signed a bill establishing the Grand Canyon as a national park. Story: The Grand Canyon was dedicated as a national park 100 years ago. This anniversary commemorates the canyon's legacy, but it has been around longer than that—at least 6 million years. Our host explores the beauty of this natural wonder with Wayne Ranney, a geologist who has spent his career studying the canyon. Listen in for a historical journey through this iconic landscape.

Stat: 100. More than half of children born in developed countries today will reach the age of 100. Story: If you knew you would live to 100, what would you do differently? Increasing longevity will expand and shift the traditional phases of life, according to London Business School professor Andrew Scott. In his conversation with host Dan LeDuc, he describes the challenges and opportunities facing individuals and society as life expectancy continues to rise.

Stat: 57 percent of social media news consumers expect what they see there to be largely inaccurate. Story: The rise of deepfakes—realistic fake videos made with artificial intelligence software—is beginning to make sorting fact from fiction even harder. In an interview with Dartmouth Professor Hany Farid, a digital forensics expert who advises governments and the media on how to meet this growing threat, we discuss the implications for people and societies when we can't necessarily believe what we see.

Stat: 50. The percentage of American children today who will grow up to earn more than their parents did. Story: That's down from over 90 percent for children born in the 1940s and its says a lot about the current state of the American Dream. John Friedman, who's a leader of Opportunity Insights which is working to help people get out of poverty, says the opportunity to move up the economic ladder depends a lot on where you live and even who your kindergarten teacher was. He speaks with host Dan LeDuc about what factors can improve kids' chances of success.

Stat: Four in 10 Americans say technology has improved their lives most in the past 50 years. Story: To end 2018, we look ahead at the promise of new technologies, which also bring challenges for societies. To understand the issues, we speak to Arati Prabhakar, former director of the Defense Advanced Research Projects Agency. From artificial intelligence to neurotechnology, she notes the "dazzling" new capabilities emerging and the thorny considerations they bring.

Stat: 21. The number of African countries where manatees live. Story: If you've ever seen a manatee, chances are you were in Florida, where these aquatic relatives of the elephant may have poked their faces above the water's surface to get a look at you. But this episode's guest studies manatees few have ever seen—the African species that live in remote, murky waters. Host Dan LeDuc talks to 2017 Pew marine fellow Lucy Keith-Diagne about what makes these creatures so fascinating—and the threats facing them.

Stat: 39 percent. That's how many Americans say they are highly religious. Story: When asked about their religion, most Americans identify with a traditional faith: Christianity, Judaism, Islam. But the Pew Research Center recently looked beyond familiar classifications and analyzed patterns of American beliefs and behaviors across many faiths. Host Dan LeDuc talks with one of the authors of this analysis, Rich Morin, about how the researchers created this religious typology and what each of the seven types means.

Stat: $764 billion. That's how much the arts contribute to the U.S. economy each year. Story: The creative process for artists can seem mysterious—what sparks an artist's initial idea and how does that idea become reality? Host Dan LeDuc talks to Pew Arts Fellow, and Pulitzer Prize- and Grammy Award-winning classical composer Jennifer Higdon about her creative process, and also interviews Paula Marincola from the Pew Center for Arts & Heritage about supporting the arts.

Stat: 61 percent. That's how many voters say they're enthusiastic about voting in November. Story: Traditionally, voters don't flock to the polls for the midterm elections. But this year, the Pew Research Center has found that voters are more enthusiastic about voting than at any point during midterms in the past two decades. Why is that and what's on voters' minds? In this episode, Dan LeDuc talks with the center's director of political research, Carroll Doherty, who will share his insights from the polling data.

Stat: 7 out of 10 babies born in London have at least one parent who wasn't. Story: London is on track to exceed 9 million people in three years and most of the new babies there have at least one foreign-born parent. One area in particular is emblematic of these changing world demographics: Brixton. Host Dan LeDuc went for a walk there with Ben Rogers and Denean Rowe from the Centre for London to see up close how it's evolving from a quintessential South London neighborhood into a dense, multicultural hub.

Stat: 70 percent. That's how many children now born in London have at least one foreign-born parent. Story: In many ways, the metropolis of London is a microcosm of what's happening around the globe. People move across borders and flock to urban centers, causing their newfound homes to evolve and adapt. How are global demographic trends affecting and changing our world? To learn, host Dan LeDuc talks with Mark Hugo Lopez, director of global migration and demography research at the Pew Research Center.

Stat: 7 in 10. That's how many Americans say that debt is a necessity, even though they prefer not to have it.

Ramsey shares his thoughts about why so many Americans are in debt today, why they're not stuck, and the key to breaking the cycle.

Stat: Four. That's how many letters in the DNA alphabet make up every living thing. Story: How does genetic information transmit across generations? While trying to find out, scientists Craig Mello and Andrew Fire quite by accident made a discovery in 1998 that would earn them a Nobel Prize—and pave the way for the first drug to take on harmful genes. Pew's Dan LeDuc talks with Mello about science's surprises. Additional audio licensed for use by the Nobel Foundation. All rights reserved. © Nobel Media 2006

Stat: North Atlantic cod have nearly tripled since 2006 to 118,000 tons. Summary: Overfishing has strained most global fish stocks. But the European Union has made progress bringing back one popular species: North Atlantic cod. The flaky white fish—a British staple when battered and served with chips—has rebounded after plummeting to critically low levels in the late 2000s. In this episode, we go to one of London's oldest fish and chips restaurants and learn how quotas can be used to help other stocks recover.

Stat: 44 percent. The percentage of Americans who think the public doesn't know enough about science to understand new findings in the news. Story: Ira Flatow, the host of "Science Friday," has been with National Public Radio since it went on the air in 1970. Although he knows the public loves science, he's worried that most people don't know how the scientific process works. Pew's Dan LeDuc talks to him about why critical thinking is crucial, who asks the best questions, and how science can be addictive.

Stat: At least 2 million Americans get antibiotic-resistant infections each year. Story: Nearly a century after Alexander Fleming's discovery of penicillin, bacteria continue to develop the ability to defeat antibiotics.

In this rebroadcast of a Pew event, she discusses what can be done to manage drug costs and ensure that Americans get the medicine they need.

Stat: At least 63 million sharks are taken from the ocean every year. Story: And that's the low estimate; others range as high was 273 million. That worldwide catch—for shark fins and increasingly for their meat—is threatening some species with extinction. In this episode, host Dan LeDuc talks with two unlikely advocates for protecting sharks: South African Paralympian Achmat Hassiem and Pew's Debbie Salamone. Both have been bitten by sharks but have turned their experiences into something positive: becoming shark attack survivors supporting shark conservation.

Stat: The ocean generates $2.5 trillion of economic benefits around the world each year. Story: Fisheries, tourism, and shipping are some of the ways we quantify the monetary value of the ocean—but it also drives weather patterns and provides more than 1 billion people with their primary source of protein. As the ocean faces increasing environmental stresses, what would an economic approach mean for conservation efforts? We explore the issue with a fishing family in Florida and Pew's Tom Dillon.

Stat: The flag that inspired our national anthem has 15 stars and stripes. Story: It flew over Fort McHenry in the Battle of Baltimore during the War of 1812. And after the fight, it was what Francis Scott Key was looking for when he asked, "Oh say does that star-spangled banner yet wave." It was, and it continues to inspire Americans today in the Smithsonian Institution's National Museum of American History in Washington. Host Dan LeDuc went there to talk to curator Jennifer Jones about the history of perhaps our most famous flag.

Stat: Antarctica is home to more than 9,000 species found nowhere else on Earth. Story: They include Adélie and emperor penguins that depend on the nutrient-rich waters that surround the continent. In 2016, 24 countries and the European Union created the world's largest marine protected area—encompassing 1.9 million square miles—in the Ross Sea. In this rebroadcast of a Pew event, the former president of Costa Rica and other ocean conservationists discuss the need to give other Antarctic waters this same protection.

Stat: The penguin population in Punta Tombo, Argentina, has declined by 43 percent since 1987. Story: Not all of those birds are dying: Many are relocating to areas with more prey—a move aided by their ability to swim 170 kilometers a day—and 200,000 breeding pairs remain in Punta Tombo. But expert Dee Boersma, known as the Jane Goodall of penguins, says the decline may foretell worrying trends in the ecosystem. Host Dan LeDuc sits down with Boersma, and hears from a few of the penguins, to learn more.

Stat: By midcentury, there will be 2 billion elderly people in the world—and 2 billion young Story: For the first time there will be as many of each group —and together they'll account for more than 40 percent of the world's population. This will have deep implications for the labor supply, family structures and finances, demands on health and welfare services, housing, and more. In this episode, we hear a rebroadcast of a Pew event in London: "How Today's Generations Are Changing the World."

Stat: 63 million Americans, many of them children, live in areas with a shortage of dental care. Story: To help alleviate this, a new kind of dental provider is being created: dental therapists, who are much like physician assistants in a medical office. In this episode host Dan LeDuc heads to Minnesota to join one of them, Christy Jo Fogarty, as she travels the state to bring dental care to children, many of whom have never been to a dentist before.

Stat: 64 percent of Americans say fake news is causing confusion over basic facts, according to the Pew Research Center. Story: It's becoming increasingly more difficult to sort fact from fiction in this digital age. In this episode, we talk to Alan Miller, who founded the News Literacy Project—an educational, nonpartisan nonprofit organization that is helping people determine what information to trust and share.

More than a third of America's national parks are battlefields, cemeteries, and other sites that honor our military veterans. But those 156 landmarks are awaiting $6 billion in needed repairs—accounting for nearly half of the National Park Service's $11.6 billion maintenance backlog. Host Dan LeDuc talks with two former service members about the peace, pride, and purpose they find at their favorite NPS sites, and why more funding is needed to restore America's national parks.

With political discourse at a stalemate, we traveled to Middle America to find some middle ground. Former Representative Lee Hamilton (D) and former Senator Richard Lugar (R) represented Indiana for a combined 70 years and always kept talking to each other. They say the rest of us can keep it civil, too. We also talk with Pew President and CEO Rebecca Rimel about how civility and a reliance on facts have underpinned Pew's work for the past 70 years. Hear the full episode at pewtrusts.org/afterthefact.

How can states use data to make government work better? Known as a national leader for his efforts to make state government more efficient, Tennessee Governor Bill Haslam shares what he's learned over two terms about tripling the state's rainy day fund, creating jobs, reforming the state's juvenile justice system, and more. In this episode, we hear from the governor on how he relies on evidence-based policymaking to ensure that state government is effective. To learn more, visit pewtrusts.org/afterthefact.

Americans have become less religious but more spiritual over time, with 59 percent saying they regularly feel a deep sense of spiritual peace and well-being. Host Dan LeDuc interviews the Pew Research Center's Greg Smith about these trends. We also turn to Patty Van Cappellen of Duke University to discuss why people turn to religion and spirituality.

Move aside, baby boomers. Millennials are one of the largest living generations, and they are not kids anymore. The oldest millennials are now 37, and they are making their mark on the workplace, politics, and America's public opinion landscape. We discuss this changing demographic with Alec Tyson, a senior researcher at the Pew Research Center, who digs into the data on who millennials are, what they care about, and the implications for us all. To learn more, visit >>> pewtrusts.org/afterthefact.

Money makes policy. As states plan for the future, tax revenue helps them decide what it can be. And nearly half the states still don't have the revenue they did before the Great Recession. Host Dan LeDuc interviews Pew's Kil Huh about this and then goes deep with Chris Hoene of the California Budget & Policy Center about how one of the nation's most populous states is dealing with fiscal uncertainty.
