77.9% of Hawaii’s population — about 1.13 M of 1.45 M residents — lives within 100 miles of Honolulu. The other 22.1% — including Hilo — sits beyond the circle.

Why this happened

Hawaii's capital is centrally located but not perfectly placed. Honolulu's 100-mile circle captures roughly two-thirds to four-fifths of the state's residents — including Honolulu (the largest city inside, ~415K). The notable exception: Hilo, sitting 205 miles from the capital. The capital itself sits 28 miles from Hawaii's population centroid — a moderate but not extreme offset.

The biggest cities inside the 100-mile radius

The top 5 most-populous places (by aggregated ZIP code population) sitting inside the 100-mile circle around Honolulu. Cities are listed by total population captured by ZIP centroids in the dataset.

#	City	Population in radius
1	Honolulu	414,987
2	Ewa Beach	83,692
3	Waipahu	72,435
4	Kaneohe	57,620
5	Mililani	54,278

The largest city outside the radius

Hawaii’s most-populous city outside the 100-mile circle is Hilo, sitting 205 miles from Honolulu. The aggregated population of Hilo’s ZIP codes alone — 52,979 residents — illustrates the gap between Hawaii’s political seat and its population centre.

The Map Radius Tool lets you change the radius (try 50 mi for an urban-suburban question or 250 mi for “a day’s drive”), drag the centre to compare Honolulu’s reach with that of Honolulu, or add a second circle for a side-by-side comparison.

Methodology (brief)

We took the lat/lng of the Hawaii state capitol building (21.3070°, -157.8583°) and drew a 100-mile geodesic radius. For every ZIP code in Hawaii, we tested whether the ZIP centroid falls inside; if so, its population counts. We then divide by Hawaii’s total population to produce the percentage. The full methodology for all 50 states is on the hub page.
