D-Place, Database of Places, Language, Culture and EnvironmentSo far, D-PLACE contains cultural, linguistic, environmental and geographic information for over 1400 human ‘societies’. A ‘society’ in D-PLACE represents a group of people in a particular locality, who often share a language and cultural identity. All cultural descriptions are tagged with the date to which they refer and with the ethnographic sources that provided the descriptions. The majority of the cultural descriptions in D-PLACE are based on ethnographic work carried out in the 19th and early-20th centuries (pre-1950). In linking societies to a geographic location (using a reported latitude and longitude) and language, D-PLACE allows interested users to simultaneously consider how cultural practices relate to linguistic ancestry, practices of neighbouring cultures, and the environment. D-PLACE makes visualizing these relationships easy, with search results available as a table, on a map, or on a linguistic tree.
