Ohio ranked tenth among all states in producing Peace Corps volunteers this year with a total of 291 volunteers. Peace Corps officials say Ohio produces 2.5 volunteers for every 100,000 state residents, and 3.6 percent of all volunteers come from Ohio. Officials with the organization's Midwest regional office in Chicago say Ohio historically has produced a total of 6,875 volunteers who have served in 139 countries. More than 210,000 Americans have served in the organization since President John F. Kennedy established it in 1961. A total of 8,073 volunteers now work with local communities in 76 countries in fields including agriculture, community economic development, education, environment and health. The agency says it promotes world peace and friendship and a better understanding between Americans and people of other countries.
