National
Union County falls below the national median — the local AMI of $90,100 is lower than the national figure of $96,300 and also below the South Dakota statewide average of $102,200. This means income limits for programs like Section 8 and LIHTC are set lower here, so households must earn less to qualify. For renters, the lower thresholds can make the difference between eligibility and exclusion from critical housing assistance.
Rent Affordability in Union County
Using the standard 30% rule — a household should spend no more than 30% of gross income on housing — here's the maximum affordable monthly rent at each AMI tier for a 4-person household.
30% AMI
$804/mo
Based on $32,150 annual income
50% AMI
$1,150/mo
Based on $46,000 annual income
80% AMI
$1,840/mo
Based on $73,600 annual income
The 30% Rule:HUD defines a household as "cost-burdened" when it spends more than 30% of gross income on housing costs (rent plus utilities). Households exceeding 50% are considered "severely cost-burdened." In Union County, a family of four earning exactly at 50% AMI ($46,000) should aim to keep total housing costs below $1,150 per month to avoid cost burden.

What These Numbers Mean For You
In Union County, the 2025 Area Median Income of $90,100 falls below the national median of $96,300. This means federal housing program income limits are set lower here — a household must earn less to qualify for the same programs that serve higher-income families in costlier markets.
For renters, the lower AMI can be a double-edged sword. While qualification thresholds are more accessible (50% AMI is just $46,000 for a 4-person household), the affordable rent ceiling of $1,150/month at that level may more closely align with actual market rents in Union County— potentially reducing the gap between "affordable" and "available."
For developers, the lower AMI tightens the economics of LIHTC projects. The 60% AMI cap for a 4-person household in Union County is $54,050, which constrains maximum allowable rents and may require additional subsidies or creative financing to achieve feasibility. For city planners in South Dakota, the gap between Union County's AMI and the statewide average of $102,200 highlights regional economic disparities worth addressing in housing policy.
