Answer:
Settlement houses:
These were found and established in lower class, inner city, urban areas. Volunteer workers lived with low-income people, and shared stories, knowledge, food, money, and advice, providing shelter, basic human needs, food, and access to education. They were usually funded by a nonprofit or a rich donor.
Fraternal organizations-
Also known as "frat houses," these are a society of men, college students at large universities, such as University of Alabama, University of Georgia, or Syracuse University, for young men to bond over brotherhood. Some of them are associated with partying, while others focus on community service and helping others. Either way, they are based on bonding people who share common interests.
Similarities: Both Settlement houses and fraternal organizations are for people with similarities to bond.
Differences: Settlement houses are generally found in lower income areas, while fraternal organizations are found on college campuses and higher income areas.
