SkaldMaps defaults to screening ZIP codes. Start with scanning all 1544 ZIPs in Illinois, then switch to counties when you need the bigger picture or drill down to census tracts for a more local view.

Why SkaldMaps

Why not just Google it?

Because the data lives in dozens of different places - and a generic "Top 10 Suburbs of Chicago" list isn't necessarily what you're actually looking for.

Data that's normally scattered across dozens of sources.

Ownership costs, schools, weather, broadband, hospital access, and market context for Illinois live in different places, formats, and geographic scales.

We did the math.

We pull the data together, map non-ZIP data to the ZIP (or county or even census tract, if you prefer) level using geospatial calculations, and build derived signals on top: access scores, affordability ratios, custom indices. One question instead of twenty.

Filter the state, not just one city.

"Show me every ZIP in Illinois under $400k where schools beat the state average and a hospital is within 10 miles and I'm within 20 miles of my office in Aurora"? Try that elsewhere.

Your priorities, your ranking.

Generic top-10 lists rank places with a fixed formula. Yours maybe weighs commute and broadband access higher than nightlife (and maybe it doesn't) - so we let you set the weights yourself.

What you can do with it

Explore and analyze Illinois's eeal estate market.

Explore the map, rank locations by your own weights, and filter the results down to a shortlist that fits.
