Little League® International takes pride in being a community-based youth sports program, and since 1939, the organization’s mission has been to provide children the opportunity to play with their friends and neighbors. To help ensure that leagues are community-based and that there is parity between leagues, every local Little League program around the world operates within a distinct set of boundaries. To be a member of Little League, any local community must receive a charter issued by Little League International. A primary component of the league charter is a count of the total number of people – the general population in the area – that the league will service and draw participants from within those boundaries.

Understanding the population within a certain geological boundary is important for all league officers to know, whether you’re a new group of volunteers looking to affiliate with Little League for the first time, or you’re looking to take advantage of Little League’s Interleague Play or Combined Teams options.

There are several free online resources available that can help a league quantify its general population.

The United States Census Bureau provides such a population discovery tool that is easily accessible. For any local league or district official attempting to complete a charter application, or enter information to operate a combination or interleague situation, use Other good resources for helping to understand a population within a league’s boundaries are local school districts, as well as through contacting the municipalities that the league serves.

If you are not sure of what leagues are near you, or are looking for an accurate boundary map for a league, the Little League Finder is a quick, easy, and free way to discover what chartered Little Leagues are operating near your location.

As Little League International continues to evolve the offerings through the Little League Data Center, local leagues can charter, purchase insurance, interleague with other Little Leagues, and establish team combinations that provide a broader opportunity for children to play in the program.

Population and location information are a necessity to have in hand when chartering with Little League Baseball and Softball.
