High-speed internet, safe to say, has become pretty essential to our lives, especially during the pandemic, and yet many Americans struggle to get it. The government has mapped internet access for years, but those maps have overestimated that access. So Congress tasked the Federal Communications Commission with making better ones. The first results came out this month: a map showing mobile coverage from four of the biggest wireless carriers. But better maps for wired broadband are still in the works. Meanwhile, Congress is poised to pass the infrastructure bill, which could allocate $65 billion to improving broadband in the places that need it most. Marketplace’s Meghan McCarty Carino interviews Nicol Turner Lee who researches technology access at the Brookings Institution. Turner Lee says this new mobile data is valuable, since about 15% of Americans — especially young and low-income ones — need it to get online.
