These are the states with the fastest — and slowest — internet speeds

The District of Columbia retains the top spot for fastest wireline internet in the country at 28.1 megabits per second, according to content delivery network Akamai’s latest State of the Internet Report. The fastest state is Delaware with an average speed of 25.2 Mbps. D.C. and Delaware are the only two places in the nation that currently surpass the FCC’s 25 Mbps broadband threshold.

At 18.7 Mbps, nationwide average internet speeds are up 22 percent year over year. The U.S. ranks 10th in wireline internet speeds and 28th in mobile internet speeds.

All the states posted substantial year-over-year gains in internet speed as U.S telecoms roll out faster networks. Ohio’s average speed increased the most at 74 percent while Utah saw the least growth at 4.9 percent.

New Mexico and Idaho round off the bottom of the list, with average internet connection speed of 12.4 Mbps and 12.0 Mbps, respectively. That’s less than half the speed of the fastest state on the list, Delaware.

Here’s the complete list of U.S. average internet speeds:

Will you support Vox’s explanatory journalism?

Most news outlets make their money through advertising or subscriptions. But when it comes to what we’re trying to do at Vox, there are a couple of big issues with relying on ads and subscriptions to keep the lights on:

First, advertising dollars go up and down with the economy. We often only know a few months out what our advertising revenue will be, which makes it hard to plan ahead.

Second, we’re not in the subscriptions business. Vox is here to help everyone understand the complex issues shaping the world — not just the people who can afford to pay for a subscription. We believe that’s an important part of building a more equal society. And we can’t do that if we have a paywall.

So even though advertising is still our biggest source of revenue, we also seek grants and reader support. (And no matter how our work is funded, we have strict guidelines on editorial independence.)

If you also believe that everyone deserves access to trusted high-quality information, will you make a gift to Vox today? Any amount helps.
