SDG Indicator 10.2.1

Indicator 10.2.1 - Earnings lower than 50% of median annual income
Data for Indicator 10.2.1 depicts the percentage of the San Diego County population over age 16 with earnings less than 50% of the median annual income. The population measured includes people over age 16 with earnings. The median income based on the ACS 2020 5-Year estimate (2016-2020) in Table S2001 is $54,427 (in 2020 inflation-adjusted values). $25,000 is approximately half of the median income, which matches the given income categories on the ACS table. Therefore, this Indicator focuses on households earning less than $25,000 per year.
NOTE: All monetary values for this indicator have not been adjusted for inflation.

CDP and Tract filters only contain data from 2015 and 2020.

Availability and Use of ACS Data

Data for this Indicator comes from the ACS estimates and is available at the county, CDP, and census tract levels. 
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 regional 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 Census Designated Place level, while the sample size of one-year data is sufficient for large CDPs, it is not for many of the smaller ones. Results at the CDP level use five-year data and are not available by year. Thus, at the CDP level, data is reported for 2015 (which is based on the 2011-2015 data) and 2020 (which is based on the 2016-2020 data).
