The village is mainly inhabited by the Chan (
Hakka tshin11 ) Clan although there are other surnames present in the village including Wong. It is a Hakka-speaking village. Historically, the village was used for livestock farming and growing crops. Today, the village is mostly uninhabited, and half of the village houses are deserted. In the 1950s and 1960s, many villagers left for the UK and other parts of the world. This was partly due to UK immigration policy at the time and with little work available in the village the inhabitants sought to earn money elsewhere. Little development has taken place in Luk Keng, mainly because the government has zoned the Luk Keng Marsh as a priority site for enhanced conservation. Moreover, the Government's planning policy has also restricted development of small houses and unilaterally designated parts of the area as conservation area, although most of it is private land. ==Built heritage==
