NCSY is divided into geographic regions throughout North America, setting up several different regions in the Northeastern United States due to the high number of participants there as well as regions spanning the rest of the United States, Canada, and Central America. Additionally, NCSY runs programming branches in Israel, Chile, and Argentina. Each region is divided into chapters, which typically span a city or a group of surrounding towns. In heavily populated Jewish areas like New York and New Jersey, counties may have several chapters.
