The current public health emergency has shown just how critical adequate and affordable broadband infrastructure is for communities and individuals trying to work, access healthcare and attempt to teach kids from home.
Yet over one-fifth of rural Americans lack access to broadband, while some estimates suggest that figure could be much higher.
The problem has spurred many US state governments to take an active role in trying to connect more rural communities to high-speed internet, whether it’s by incentivising providers to serve rural areas or creating dedicated offices aimed at helping more people get online.
As part of our ongoing research on how broadband access affects economic development, we conducted a study that examined which of these state policies are actually working in the US.
The pandemic has brought home the importance of high-speed internet access in all manner of everyday life. Recent studies have found that broadband matters for jobs, income, business relocation, civic engagement and health.
While availability has generally increased over the past decade, there is still a significant ‘digital divide’ in terms of who has access to broadband. The latest data available shows that in some US states, less than 50pc of rural residents have a broadband connection available where they live.
Policies meant to increase access
Many state governments have adopted one or more of three approaches that can affect broadband availability: establishing broadband offices, increasing funding and restricting municipal networks.
In 2018, 25 states, including Minnesota, Tennessee and North Carolina, had offices with full-time employees devoted to getting more residents connected to high-speed internet. In general, they work with providers and communities to find ways to connect those without high-speed connections and to improve adoption rates where broadband already exists.
A total of 18 states, such as Colorado and California, had special funding programmes that help subsidise broadband deployment in rural areas. These programmes offer financial incentives to providers to install broadband infrastructure in lower-density areas where obtaining a profit is more difficult.
Utah, Wisconsin and 18 other states have adopted policies that restrict the ability of cities, utilities and other public entities to build their own broadband networks. Supporters of these restrictions, which aren’t intended to increase access, argue that municipal networks represent unfair competition to private providers.

We wanted to know how these policies affected the share of rural Americans connected to either standard broadband – with download speeds of at least 25Mbps – or a fibre-optic network. We also considered how the policies affected competition, defined as access to two or more providers. We analysed data from 2012 to 2018 on all 3,143 US counties and focused on the changes in the rural portions of each county since a policy was put in place. We performed a regression analysis to tease out the impact of each individual policy in states that implemented more than one.
We controlled for a variety of characteristics that might also affect broadband availability, such as population density, income and education. We also factored in political ideology, under the assumption that more conservative residents and legislatures are less likely to support a broadband office or funding and more likely to impose municipal broadband restrictions.
Assessing the impact
Overall, rural areas in the US saw an average increase in broadband availability of 47 percentage points, rising from 24pc in 2012 – around when many states began implementing policies – to 71pc in 2018. Access to faster fibre climbed 16.5 points to 23pc.
But these figures varied widely depending on which state a rural American lived in – and what policies were in place.
Having a dedicated funding programme turned out to have the greatest positive impact on getting more people in rural areas connected to broadband and fibre. Our analysis found that the policy increased broadband access by an average of 1.8 percentage points compared with states without the policy in place. Gains for fibre were even higher at 2.1 percentage points. The share of counties with access to more than one broadband provider climbed 1.4 points above what would otherwise be expected.
Imposing restrictions on municipal broadband, on the other hand, had a significant dampening effect on internet access. Counties whose states imposed such restrictions experienced broadband access gains 3.7 percentage points less than what they would have enjoyed without the policies in place. Fibre access was 1.6 points less, while the policy had a negligible impact on competition.
We found that state broadband offices had little impact on the availability of broadband or on the number of competitors, though they did lead to higher fibre availability, raising access by 1.5 percentage points more than in states without the policy. Recent research has emphasised the importance of the faster speeds that fibre provides for economic growth and employment.
But since broadband offices are relatively new, we believe the jury is still out on how effective they are. Other research has found benefits to broadband offices, such as better planning and outreach. It may just take more time for more of their benefits to show up in the data.
Moving in the right direction
Putting it all together, we would estimate that a state like Louisiana – with restrictions on municipal broadband and no dedicated funding programme – could improve rural access to broadband by 5 percentage points above their normal rates of growth over the next six to seven years by changing those two policies.
And it seems like some US states may already be aware of the advantages of doing so. In 2019, seven more states put in place funding programmes to encourage broadband, and five softened their restrictions on municipal networks. Tennessee is currently considering removing its restrictions entirely.
On the whole, states have made significant gains in narrowing the rural-urban digital divide. Hopefully, states that have seen less improvement will learn from their neighbours.
But access is only part of the equation. Another important factor is affordability, which is why it’s important to pursue policies that can increase competition and reduce prices, too.
