To find a youth indoor soccer league in your area, start by contacting major youth athletics organizations such as the American Youth Soccer Organization or the Young Men's Christian Association. The availability of different types of leagues varies by region.
AYSO, the oldest youth soccer program in the United States, was created in 1964 in California. It has grown exponentially, and now has programs in approximately 900 communities around the nation. It's a not-for-profit organization that provides the opportunity for boys and girls from age 3 through age 19 to participate in soccer programs. AYSO is a program focused on development and gives equal opportunity for children of all skill levels to participate; its website states that every player on every team plays at least 50 percent of every game.
The YMCA is also a national not-for-profit organization that has locations in 10,000 neighborhoods across the country. It has been in existence for nearly 160 years, and offers youth sports programs in soccer as well as other sports. Because of the reach of these two organizations, it is likely that a youth indoor soccer program is offered near most potential players' locations. If not, another option is to contact the city's parks and recreation department to find out more about local youth sports offerings.
