The north atlantic population project an overview

The North Atlantic Population Project (NAPP) brings together complete-count census data from late-nineteenth-century Canada, Great Britain, Iceland, Norway, and the United States into a single harmonized database. When released in 2005, the final version of the database will include the records of nearly 90 million people. The project will consistently code all variables across the different countries, while still retaining important national variation in census questions and responses. The authors provide a brief history of the project, discuss the main issues involved in creating a harmonized international census database, and outline the methodological and research opportunities the completed database will provide for scholars.
