SDG Indicator 9.c.1

Indicator 9.c.1 - Broadband access
Data for Indicator 9.c.1 illustrates access to a broadband internet connection and a computer within the San Diego region.
The measure cards and line graph below show a steady increase in broadband accessibility between 2015 and 2021, reaching an overall high of 96% in 2021.

The bar graph and map below further analyze the distribution of broadband access by jurisdiction and census tract. Connectivity is noticeably less widespread in certain parts of National City, El Cajon, and Ramona.

Availability and Use of Data

Data for this Indicator comes from the Census Bureau's American Community Survey (ACS) estimates. Population counts come from Table S2802 using the filters for households with a computer and with a broadband internet subscription.
 The choice to use one- or five-year data is based on the geography type and the type of analysis for which it is needed. 
 One-year data has a sample size sufficient to report results and compare change over time at the county level. However, the Census Bureau recommends against using one-year data for 2020 due to the impact of the COVID-19 pandemic. Therefore, time-series results using this data will not have a value for 2020.
 The sample size for one-year data is insufficient at the census tract level.  Therefore, results at this level use five-year data. 
 At the jurisdictional level, while the sample size of one-year data is sufficient for large jurisdictions, it is not for many of the smaller ones. Results at the jurisdiction level use five-year data and are not available by year.  Thus, at the jurisdictional level, data is reported for 2015 (which is based on the 2011-2015 data) and 2020 (which is based on the 2016-2020 data).
