The Meriam Library has been given trial access to Social Explorer. Social Explorer is an online research tool designed to provide quick and easy access to historical census data and demographic information. It creates fast, intuitive, and appealing maps and reports to help users visually analyze and understand demography and social change throughout history. The site currently includes the entire US Census history from 1790 to 2000, all annual updates from the American Community Survey, and the Religious Congregations and Membership Study from 1980 to 2000. The site is updated three times annually with new data – the 2010 US Census will be available shortly after its release – and new features will be continually added.
