Broadband Connection

Percentage of households with high speed broadband internet connection (cable, fiber optic, DSL)

Why do we measure broadband connection?

Access to high-speed broadband, defined by the Federal Communications Commission (FCC) as a minimum connection speed of 25 megabits per second (Mbps) for downloads and 3 Mbps for uploads, has become critical to community health and economic well-being.1,2 Reliable, high-speed internet improves access to education and employment opportunities and is associated with increased economic development, higher home values, and higher educational outcomes at both the grade school and high school levels.2-4 It can also enable people to access healthcare resources, by, for example, finding a local doctor or connecting to care remotely.4 For these reasons, lack of high-speed broadband can have a negative impact on health outcomes in the short and long term.

The COVID-19 pandemic and associated shutdowns underscored the importance of broadband access and highlighted the impacts of deep disparities in broadband access across communities.3 Indeed, it is estimated that about 30% of U.S. households do not have high-speed internet access.5 While the rural/urban “digital divide” gets a lot of attention, significant disparities in broadband access can be found within cities as well.6 In fact, in the U.S., urban counties contain a higher share of all unconnected Americans (35%) than do counties that are mostly rural (8%).7 In urban areas, lack of access to broadband is most frequently due to the cost of subscription, low digital literacy, or lack of in-home computing equipment, compared to rural areas, where lack of physical infrastructure is often the principal barrier.8 Lack of access to broadband internet during the pandemic has exacerbated existing disparities for those who are already at higher risk for poorer health outcomes, such as people of color and those who are older, have lower incomes, or are less educated.6,8,9 Within the largest U.S. cities, for example, people of color represent 75% of those who are unconnected, yet only 61% of the population.7

How do we measure broadband connection?

This metric estimates the percentage of households that have connections to high-speed broadband internet in the home. This includes households with cable, fiber optic, or DSL connections, and excludes those with satellite or dial-up connections.10 This metric does not include households that access the internet entirely through cellular data plans.

Strengths and Limitations

Strengths of Metric

Limitations of Metric

• In the increasingly digital world, improving access to broadband connection at home is critical for reducing disparities in health outcomes.

• The metric only includes broadband connection types (cable, DSL, and fiber) with higher (and thus more useful) connection speeds.10

• This type of self-reported metric asks households for the type of internet connection they have. Some people may not know how they get their internet.

• Not all cable, DSL, and fiber connections are created equal. Some may be faster or slower than others, and this metric does not measure internet speed or quality. Access to only low-speed or low-quality internet may also have a negative impact on health disparities.



Broadband connection is calculated by the following formula:
