Places within a radius

Find cities and towns within a radius

Draw a circle around any address to list every town and city inside it, with distance, direction, and population. Sort the list, show it on the map, and download it as CSV.

Approximate distances on a spherical Earth. Straight-line distance, not driving routes. Polar regions are clipped by the map projection.

Click an empty part of the map to add a circle. Drag a center or edge to adjust it, or use the radius and center coordinate fields.

Towns and cities inside the circle

Scroll here to list the places inside the selected circle.

Lists places with at least 15,000 residents from GeoNames (CC BY 4.0), measured to each place’s reference point. Population figures come from various census years and boundary definitions, so treat them as indicative. Districts are parts of a larger city that are listed separately.

How the places list works

Below the map, Towns and cities inside the circle lists every place with at least 15,000 residents whose reference point lies inside the selected circle. It updates as you drag the center, resize the edge, or select another circle. Each row shows the place, its state or region, the straight-line distance and compass direction from the center, and its population.

  1. Search the center address, city, or coordinates, or click the map.
  2. Set the radius and unit. The list works for any radius up to 2,500 km (1,550 miles).
  3. Sort by Nearest first, Largest first, or A–Z, and select a place name to zoom the map to it.
  4. Choose Download CSV to open the list in a spreadsheet, CRM, or mailing tool.

What people use a cities-within-radius list for

  • Sales territories and service areas. List every town a branch or technician can cover, then split the territory between bases by adding a second circle.
  • Relocation and job searches. List the towns within commuting distance of a new job and sort them by size.
  • Marketing and advertising. Build a list of target towns for a regional campaign, or check which cities a radio or ad-targeting radius would reach.
  • Events and logistics. See which population centers fall within a day trip of a venue, or which cities a depot can reach for same-day delivery.

How many towns fall within 25 and 50 miles of major cities?

The table counts separately listed towns and cities with 15,000+ residents around each city’s central reference point, excluding the city itself and its districts. Kilometer-based cities use 40 and 80 km, which are close to 25 and 50 miles.

Counts depend on how each country’s places are recorded in GeoNames; some countries list suburbs as separate towns and others merge them into one city.

Limits of the data

The list is built from GeoNames, an open geographic database (CC BY 4.0). It includes places with at least 15,000 residents, so villages and small towns are not listed, and population figures come from different census years and boundary definitions. A place is included when its reference point, usually its center, is inside the circle; a large city whose center is just outside will not appear even though some of its neighborhoods are inside. For US ZIP codes, use the ZIP code list under the same map. For census tracts or exact boundaries, export the circle as GeoJSON or KML and overlay it in GIS software.

Questions, answered

Frequently asked questions

How do I find cities within a certain distance?

Search the center location, set the radius, and scroll to Towns and cities inside the circle. The list updates whenever you move or resize the circle, and you can sort it by distance, population, or name.

Which places are included?

Cities, towns, and separately listed city districts with at least 15,000 residents in the GeoNames database, about 34,000 places worldwide. Villages and smaller towns are not listed.

Is there a limit on the radius?

Places are listed for any radius up to 2,500 km (about 1,550 miles). There is no small limit such as 50 km, so you can list every larger town in a whole region.

How is distance measured?

Distance is the straight-line (great-circle) distance from the circle’s center to the reference point GeoNames records for each place, usually its center or town hall. A town is listed if that point is inside the circle, even if part of the town extends beyond it.

Can I download the list?

Yes. Download CSV saves name, region, country, coordinates, population, distance in meters, and compass direction for every place in the current sort order.
