The Daya live in the Barisan Mountains in the southern part of South Sumatra province. They speak a dialect of the Lampung Api language. Although the Daya can understand Lampung Pesisir and Komering, they do not identify ethnically with the Komering. Instead they identify with the Lampung Pesisir and Ranau people who live to their South. The Daya are spread throughout the two subdistricts of Simpang and Muara Dua in South Ogan Komering Ulu regency in South Sumatra.

The Daya live in the same area as the Aji and Komering. The mixing of the Daya villages among Komering and Aji villages is unique in that their villages are often in an alternating pattern geographically. On a trip from Simpang to Muara Dua Kisam, one will find alternating Aji, Komering and Daya villages, though there are fewer Aji villages than Daya and Komering. The Daya live at an elevation of 100-500 meters above sea level. Many varieties of plants can grow in this fairly fertile area. The Komering often consider the Daya to be a part of the Komering because they use the same language. There are many similarities between the Daya and Komering languages. However, the Daya feel that their language and identity are distinct from the Komering. Even so, the Daya don't deny that there are many similarities between the Daya and Komering languages. Linguistically speaking, the Daya use the Daya dialect of the Lampung Api language. Farming in this area is successful. Harvest can be done two or three times per year. This work is generally done by Javanese who manage the rice fields, either as owners or as laborers in fields owned by the Daya. If someone becomes a laborer in the rice fields, he will receive a portion that is one-half or one-third of the total harvest. The Daya typically don't manage their rice fields well, therefore many of them entrust their land to Javanese managers. A Daya family will often own 1-2 hectares of rice fields. The housing style among the Daya has shifted from the traditional raised wooden homes to more modern cinder block and concrete homes built at ground level. Sometimes they follow the design used for Javanese homes. In the areas where the Daya live in the hills, there are few Javanese because the Javanese usually live among the rice fields or other fields.

The Daya's Islamic beliefs are strongly held. For example, one young man told the story of a Chinese person who married with a local Ogan person. He explained: "Chinese, but Muslim…!" This story displays that Islam is still a strong part of their identity. Even so, almost every village has a burial ground for the ancestors that is guarded and taken care of well. There are even tombs that are seen as so holy that some people will come time after time to pray and make special requests.

Jobs are hard to come by in this area. Many young men are unemployed because there is no work in the village and they are reluctant to leave for the city. The surrounding people groups tend to view the Daya youth as lazy. Only a small number of the young men here seek work outside the local area. Character building and skills development for the young men would assist them greatly.
