The Digital Divide in the San Diego Region
The internet is a fundamental part of life.
The COVID-19 pandemic has presented tremendous challenges, especially people without internet access.
High-quality, high-speed internet service is referred to as broadband. Inequities in broadband availability and affordability impact households and businesses across the region. The growing gap between people who do and do not have reliable access to broadband and a suitable device for connecting to the internet is known as the digital divide. This divide has been exacerbated by the COVID-19 pandemic, and without new policies and programs to address this issue, it will continue to worsen.
Broadband service relies on a network of communications infrastructure.
Fiber is the backbone of broadband networks. The middle mile brings the internet to network hubs at population centers. From there, Internet Service Providers (ISPs) make the last mile connection to homes and businesses through wired or wireless technologies such as 5G, fiber, satellite, cable, or DSL.
Not all internet connections are considered “broadband.”
The Federal Communications Commission (FCC) defines a broadband connection as one with a minimum download speed of 25 Mbps and a minimum upload speed of 3 Mbps, or 25/3 Mbps. However, these speeds are inadequate for today's environment where many people under one household may be online doing schoolwork, telework, or streaming video games or television. Recognizing this, the State of California has set a new broadband standard of 100 Mbps download and 20 Mbps upload.
The digital divide affects urban and rural communities differently.
This map shows where fixed broadband meets the FCC’s broadband standard of 25/3 Mbps. The lack of broadband service in the unincorporated parts of the County means that only 66% of rural communities have access to fixed broadband that meets the FCC’s low threshold. In comparison, 94% of people in the region’s urban areas have access to fixed broadband service.
Most of the region is only served by one or two broadband providers, leaving rural and tribal communities with little to no choice of service and speed.
Affordability is one of the main barriers preventing people from subscribing to an internet service plan, according to a survey by the California Emerging Technology Fund (CETF).
The cost for internet plans differs throughout San Diego County, but many rural and tribal communities experience disproportionally higher costs.
The higher-cost internet services tend to be located in areas with limited choices of providers, directly impacting rural, tribal, and low-income communities.
Paying more does not always equate to better service.
Rural and tribal communities are often constrained in their choice of internet service providers and end up paying more for speeds that do not meet the minimum 25/3 broadband threshold.
The summary of internet plans in San Diego County (left image) shows how higher charges in monthly rate changes does not directly equate to higher download speeds.
Data on broadband costs comes from Broadband Now.
Lack of a computer and/or broadband subscription disproportionately impacts low-income households, seniors, and minority populations, as illustrated in the maps below.
These gaps in broadband service throughout the region are also where the greatest gaps in infrastructure exist.
Although more granular data on broadband infrastructure is unavailable, SANDAG, with the help of Caltrans and data from the CPUC, was able to identify the census blocks where broadband providers have invested in fiber.
In addition to fiber that is owned and managed by private companies, government agencies like SANDAG, Caltrans, North County Transit District (NCTD), and Metropolitan Transit System (MTS) have invested in fiber to operate transportation services and systems. Currently, this fiber is exclusively used for transportation purposes, but excess capacity could be shared to expand access and bring down costs of broadband service.
Strategies to Bridge the Digital Divide
Broadband is a necessary public service. To achieve our vision for a connected region, these seven overarching strategies have been developed to address the range of digital inequities that exist in the region today.
