COMMON QUESTIONS

Delaware county map questions.

What are Delaware’s three county GEOIDs?

Kent is 10001, New Castle is 10003, and Sussex is 10005. Use all five characters when joining data.

Which shape should I use for Wilmington-area county statistics?

Select New Castle County. Use the source’s county-level record when you color it.

Where does Dover appear in this map?

Use Kent County for the county-level map of the Dover area. A city-level Dover figure describes a smaller area.

Why do some examples use only two colors?

Three county observations support a short scale. The renter burden map divides those estimates at 50% and both bands have counties.

Why is New Castle gray in the cleanup example?

The fictional CSV has rows for Kent and Sussex. New Castle keeps the neutral fill because the example leaves it outside the sample.

How do I show coastal Delaware in a report?

Use the Sussex shape with its generalized bay and ocean edges. Preview the full state before exporting so the coastline stays visible.
