Secondary Data Analysis
Captions available
The idea
Secondary data analysis uses data already collected by someone else — a census, an agency, an earlier study — to answer a new question.
In practice
A researcher studying housing uses decades of census records no single project could have gathered.
Where people slip
The data were shaped by the original purpose, and its categories come with them.
