The ACS 5-Year Drop: Notes from a Long Night

The latest ACS 5-year estimates are out. Here’s how I read a new release, plus a quick San Diego example.

The 2020–2024 American Community Survey (ACS) 5-year estimates are officially out.

I build dashboards for work, but last night I was also on baby duty. At 7:00 a.m., I ended up refreshing pages and skimming tables with one eye open.

What the ACS 5-year file is (and isn’t)

The ACS 5-year estimates combine survey responses across 2020–2024. That makes them one of the best sources we have for small-area data, but it also means they move slowly.

I treat it like a time-lapse, not breaking news. If you are comparing places, focus on big differences. Tiny changes are often just noise.

What I look at first

When a new ACS vintage lands, I usually start with a few “pressure points”:

  • Housing costs vs. income
  • Rent burden (the share of renters paying 30%+ of income toward rent)
  • Household churn (moves, roommates, multigenerational living)
  • The goal is simple: find where everyday life feels tight, and why.

    A local example: San Diego County

    San Diego is not just nice weather and the city where Ron Burgundy proudly calls home. It’s also a place where the cost of living can make a good income feel smaller than it looks. I feel this sentiment from friends, family, and neighbors.

    Here are a few numbers from San Diego County:

    • Population: 3.3M
    • Median household income: $110.5K
    • Median home value: $904.4K (about 8.2× of income)
    • Rent-burdened renters: 58.6% (30%+ of income)

    San Diego County benchmarks (dollars)

    Rent-burdened renters (≥30%)

    58.6% • state median 54.1% • US rate 51.1%

    Severely rent-burdened (≥50%)

    30.4% • state median 27.7% • US rate 25.9%

    Rent burden is the share of renter households paying 30%+ of income toward rent. Severe rent burden is 50%+. That first threshold is the one I keep coming back to. It’s a quiet tax on flexibility: it limits saving, moving, and even small decisions that should be easy.

    Closing thought

    I love data, but I care about what it helps us see. These numbers are a snapshot of the world our kids are growing up in.

    If you're curious, pick your ZIP code or county and compare it to nearby places. Sometimes the story is exactly what you expect. Sometimes it isn’t.


    Methodology note: USA Viz uses ACS 2020–2024 5-year estimates and (for ZIP pages) ZCTA geography. Small-area estimates can have higher margins of error; treat small differences as noise rather than precise changes.
