Catchment area

The catchment area is an essential element when creating a company or opening an establishment. It allows you to visualize the geographical area of influence of an establishment and to estimate its potential. Visually, a catchment area is represented by an isochronous area, i.e. the area that can be reached for a travel time from an establishment.

Example of an isochronous zone (1 hour by car from Toulouse)

A catchment area is generally defined by several time zones in order to define several sectors of attractiveness: primary, secondary and tertiary. For example:

  • Primary Sector: 5 minutes by car
  • Secondary sector: 15 minutes by car
  • Tertiary Sector: 30 minutes by car

Travel times and mode of transport in each sector depend heavily on the business. For each sector of activity, an attraction rate is defined to estimate the population that can be captured in this area. This means the percentage of people in the area likely to come to the establishment. With this information and by studying the competition in each sector it is then possible to estimate the potential of the new activity.

With Oalley it is possible to create and visualize free of charge catchment areas for a very large number of means of transport (walking, cycling, car and public transport...). In addition, the interactive map makes it very easy to explore these areas. To visualize your catchment area go to the map.

The professional version of Oalley provides key information on the sectors studied, here are some examples of data that can be obtained on a catchment area:

  • Number of people living in the time zone
  • Gender distribution
  • Age of the population
  • Employment
  • Housing

With this information it is then possible to estimate very quickly the potential of a new establishment. If you need more information, don't hesitate to contact us.
