SDG Indicator 3.8.2

Indicator 3.8.2Proportion of population with large household expenditures on health as a share of total household expenditure or income

Indicator 3.8.2 is a critical measure which aims to support the United Nations sustainable development goal (3.8) of achieving universal health coverage, not only by recognizing access to essential health services, but also by identifying if they cause financial hardships for lower-income households. 
In the past few years in San Diego County, there has been demonstrated progress in healthcare access and coverage for all residents.
In 2015, 91.2% of the population was covered by healthcare services, a figure that increased to 91.99% by 2019. By 2021, this percentage rose further to 93.3%, which exceeded the national average of 91.7% at the time (as reported by the US Census Bureau). Despite the increasing coverage percentages, a considerable proportion of lower-income families may remain underinsured or struggle with out-of-pocket expenses. This issue underscores the ongoing need for targeted interventions to ensure that universal health coverage is not only achieved in terms of access but also in terms of affordability, particularly for those in financially vulnerable situations.

Health Insurance Coverage by Income Level

Across all income levels, there was an increase in the percent of people covered by health insurance between 2016 and 2021. Higher income households tend to have a greater proportion of coverage than lower income individuals due to greater financial resources to afford healthcare costs. One notable exception is individuals with income levels between $25,000-$49,999 having somewhat lower levels of health insurance coverage than households with annual incomes below $25,000. This difference is accounted for by the availability of public health insurance programs such as MediCal which are based on income-level and household size, with less accessibility for individuals with incomes of $25,000-$49,999, even if health coverage still poses a financial burden.

Proportion of Low-Income Individuals with Health Insurance

This map displays the proportion of low-income (annual income below $25,000) households who have some form of health insurance, whether it's public or private, within a given jurisdiction of San Diego County.
