About one-in-five American adults use a smart watch or fitness tracker, with women more likely than men to use a fitness device, according to new research from Pew.

Why it matters: The category is still in its early days, and understanding who uses the products and who doesn't could help the industry improve its products and broaden their appeal.

By the numbers: Pew says 21% of Americans report using a smart watch or fitness tracker. Here's how that breaks down:

  • 18% of men and 25% of women.
  • 20% of whites, 23% of blacks and 26% of Hispanics.
  • 25% of those 18-49, and 17% of those over 50.
  • 31% of those who make $75,000 or more, 20% of those who make between $30,000 and $74,999 and 12% of those who make less than $30,000.

Meanwhile: Respondents were also asked whether it is acceptable for device makers to share user data with medical researchers. About 41% said that it is acceptable and 35% said it isn't, with 22% saying they were unsure.

Biden confronts mounting humanitarian crisis at the border

Just over a month into his presidency, President Biden is staring down a mounting crisis at the border that could be just as bad as the ones faced by Barack Obama and Donald Trump, if not worse.

Why it matters: Immigration is an issue that can consume a presidency. It's intensely and poisonously partisan. It's complicated. And the lives and welfare of vulnerable children hang in the balance.

The rise of vaccine passports

Vaccine passports were touted early in the pandemic as an important piece of the plan to get people back to normal life. Now they’re becoming a reality.

Driving the news: CLEAR, the secure digital identity app that you see in airports around the world, and CommonPass, a health app that lets users securely access vaccination records and COVID test results, have joined forces.

"Vaccine tourism" stretches states' supplies

Americans who are highly motivated to get vaccinated are traveling across state lines after hearing about larger vaccine supplies or loopholes in sign-up systems.

Why it matters: "Vaccine tourism" raises ethical and legal questions, and could worsen the racial socioeconomic and racial inequalities of the pandemic.
