The population of the island is currently around 34 souls and is similar to that of 60 years ago. The main demographic change has been the replacement of mainly gaelic speaking West Highlanders by families from all over the UK. This is similar to what is happening everywhere in the North West. The estate owns most of the houses on the island. These are let to the islanders and from time to time one may become available to anyone wishing to join the community (please see the properties to let page).

There is a fine modern school with a nursery class and six children in primary. At the age of twelve pupils have to continue their education in Mallaig which entails boarding during the week and every second weekend.

Muck has no mains electricity. The island is powered by a community run wind power scheme. On windless days there is a back-up diesel generator to supply the island with electricity. Prior to the wind turbines each house had their own diesel generator. A new pier has recently been completed allowing the Caledonian MacBrayne ferry to dock at Muck. Previously passengers and freight had to be offloaded into a flit boat to complete the journey to shore.

Visitors are welcome to attend any community events, such as church services or ceilidhs, while they are here.
