It is ethnically more diverse than Talinji. Pulaiyar were the majority inhabitants of Manjampatti when the British gave land to the village for cultivation. About 15 families of Muthuvar, another "tribal" group, live in Manjampatti village where they do cultivation and labor work. Some Theivar people, a widespread plains agricultural jaathi (caste), came to live in Manjampatti long ago and engage in agriculture on the village lands. There are also a few houses of other plains jaathis such as Chakkliyar (originally leather-workers). Because of these jaathis, Manjampatti village has some features of plains Tamil villages such as eating of newer types of vegetables and having tea shops.
