Locate the statistics for free and reduced lunches at a website such as City-Data, which gives such data about schools.
Visit your school district's website. Many school districts post lunch data for informational purposes. You can find you school district's website by searching on Google, Yahoo, Bing or another search engine.
Call the school directly to inquire about the information. Ask to be transferred to the school's cafeteria, if the receptionist or the main office is unable to give you this information. Cafeterias have staff members who will be able to give you these statistics.
