Draw a Radius and Instantly See Population

Draw a radius around any location and instantly calculate how many people live within that area. Whether you're evaluating a site, defining a territory, or analyzing a market, you can get answers in seconds.

How Many People Are Within Your Target Area?

Every location decision starts with the same question:

• Is there enough population here to support a new store?

• How far will customers realistically travel?

• Is this territory too small or too large?

A simple radius gives you a fast way to define an area. But the real value comes from understanding what’s inside it.

Population within a radius is one of the fastest ways to evaluate a market before going deeper.

What Is a Radius Map?

A radius map is a circular area drawn around a specific location.

For example, you might draw:

• a 1-mile radius around a retail site

• a 5-mile radius around a clinic

• a 10-kilometer radius around a city center

This represents a straight-line distance from a central point.

It’s a quick way to define a trade area, especially when you need a fast estimate of reach.

Go Beyond Radius Maps — Measure Population Within Any Area

A radius map shows you where.

Population data shows you what’s there.

Instead of just drawing a circle, you can measure:

• Total population within the radius

• Population density

• Demographic and income data

This is what turns a simple map into a decision tool.

How to Calculate Population Within a Radius

Calculating population within a radius takes just a few steps:

1. Choose a location

In Population Explorer, either zoom in through the map viewing pane to save a marker on your ideal location, or search for the location through the POI feature.

2. Set your radius

Define the size of your area — for example, 1 mile, 5 miles, or 10 km using the 'buffer tool' in Population Explorer.

3. Measure population

Either hover over the shape, or click it to reveal total population with age and sex disaggregation.

When to Use a Radius Map

Radius maps are most useful when you need a fast, consistent way to evaluate an area.

Site Selection

Quickly assess whether a location has enough nearby population to support a new store, clinic, or service area.

Franchise Territory Planning

Define territories with consistent population coverage, helping ensure fairness and performance across locations.

→ Learn more about mapping ideal franchise territories

Sales Territory Design

Balance territories based on population instead of arbitrary boundaries, reducing overlap and improving coverage.

→ Learn more about creating balanced sales territories

Market Analysis

Understand how demand changes across different locations by comparing population within similar radii.

Radius vs Drive Time — What’s the Difference?

A radius measures straight-line distance.

A drive time measures how far someone can travel using real roads within a set amount of time.

• Radius → fast, simple, consistent

• Drive time → more realistic, more precise

Radius is ideal for quick analysis and early-stage decisions.
Drive time is better when travel behavior matters.

Analyze Competitors Within Your Radius

Population is only part of the picture.

You can also analyze what else exists within your radius:

• Competitor locations

• Retail clusters

• Points of interest

This helps answer questions like:

• Is this market already saturated?

• Are there gaps in coverage?

• Where are competitors concentrated?

Frequently Asked Questions

How do I calculate population within a radius?

Choose a location, define a radius, and generate the area. Population Explorer calculates how many people live within that boundary instantly.

What is a radius map used for?

Radius maps are used to define trade areas, evaluate locations, design territories, and understand market reach.

What radius should I use for site selection?

It depends on the business. Smaller radii (1–3 miles) are common for urban retail, while larger radii (5–10+ miles) are used in suburban or rural areas.

What’s the difference between radius and drive time?

A radius is a straight-line distance. Drive time accounts for real roads and travel conditions.

Is radius-based analysis accurate?

It’s a fast and useful approximation. For more precise analysis, especially where travel matters, drive-time areas are more accurate.
