The 2001 Census gives the population of Upper Cumberworth and Lower Cumberworth combined as 1,222.
The local woodlands are managed by the Upper Dearne Woodlands Trust, who undertake tasks such as habitat conservation, access management, education and information. Many public footpaths run through the woodlands with information boards about the plants and animals you may see. The woodland runs into Birdsedge and contains approximately 70 American Red Wood ant nests.
The village has a pub 'The Star Inn', a small shop incorporating a Post Office, a first school and a small church called St Nicholas C of E (Church of England). The churchyard still has a set of old stocks by the entrance and some interesting sculptural gravestones. There is a small children's playground and a larger field which contains football and basketball facilities. This field (known locally as the 'rec') hosts the yearly village bonfire.
Cumberworth Carnival is held every year, often within the grounds of the first school. The carnival includes a parade of 'floats' made by the villagers by decorating flat bed trucks, one of which is covered with tissue paper flowers and carries the carnival king and queen for the year, usually pupils of the first school. Stalls selling cakes, plants and books are set up in a marquee on the school field alongside tombolas and games. Sometimes the carnival includes demonstrations from local groups such as the flyball and dog agility group 'Springers' and the model helicopter group. For the 2007 carnival, the evening event included a live band for the second year running, and a barbecue.
Unconfirmed myths and legends: A wooden chair kept by the church was once sat in by Cromwell. The Cumberworth Chalice kept in the Tower of London belongs to the church. A book about the Denby Dale Pie says that the people of Cumberworth tore apart the first giant pie like wild animals, and it was 'flung to the winds'.
