Dataset of both published and unpublished material culture related to children from the Thule Culture and the Norse settlers in Greenland during the Little Ice Age. The dataset is part of the PhD-project titled 'Playing to Survive: Comparative Archaeological Perspectives on the the Role of Early-Age Innovation for Societal Adaptation during Climatic Crises', and is related to an article called 'Playing to Survive: The Role of Early-Age Innovation During the Little Ice Age in Greenland' (unpublished). The project seek to examinate the role of children and toys in innovation and adaptability during periods of climatic changes in the past. The data have been collected in the period February to May 2022. Most of the data stems from old excavation reports published in Meddelelser om Grønland. Another great part of the data stems from the National Museum in Nuuk, Greenland. All data have been registered by an item-number, an item-name (what is it), a type, number of items, locality, area, part of Greenland, find context, field, coordinates, society, culture, stage, dating, manufacture (simple or composite), material(s), measurements, finder, year of finding, other comments, references, and museum-number. Not all information is available for all entries. NA marks where the data was non-applicable. A dash (-) marks where the data is unknown (e.g. unknown measurements). There are five different types of material: game, social, transport, tool, and weapon. The sheet called 'calculations' show the percentage calculations for the material divided into time slots of 200 year. The percentages allow you to compare the material from the two cultures. The sheet called 'Diversity Index' show the calculations for the Shannon Diversity Index for each object category in each timeslot. This can be used to look at changes in diversity and absolute numbers over time.
