NDIA has created maps from the latest Census data…
The interactive maps below are based on new Census data released on December 6, 2018 as part of the 2017 American Community Survey (ACS) 5-Year Estimates.
For the first time, the 2017 ACS includes computer ownership and internet access information for local Census tracts. (Note: The Census uses the term “internet access” to refer to actual household connections, not just availability.) This information, presented in ACS Tables B28002 through B28011, was previously released only for communities of 20,000 or more and only on a community-wide basis. (NDIA’s Worst Connected Cities reports are based on this ACS citywide data.)
I was most interested in the map that shows where we lack access…

But the map of access is important too…

Both maps are interactive if you visit the NDIA site.
