Data & Statistics
Datasets are the raw pieces of information that are collected through surveys and other research tools and analyzed through statistics like "55% of state prisoners were serving sentences for violent offenses at year-end 2016" (Bureau of Justice Statistics, Prisoners in 2017). Researchers publish statistics from individual studies in academic journal articles, but comprehensive statistics are also collected by non-profit research groups and government agencies at the local, state, national, and international level and published on the web for the public.
When would I need to find statistics and datasets? If you're working on a research project about a community or social issue, you might use statistics collected by nonprofit or government researcher to describe your population/problem and show why its important.
