Secondary Sources
Why reinvent the wheel? Secondary sources let researchers use data that already exists, saving time and money while often providing access to information they could never collect themselves.
Official statistics from government departments give you massive datasets covering entire populations - perfect for spotting broad social patterns. However, they might not answer your specific research question, and there could be political motivations behind what gets measured and how.
Documents and archives provide historical context and access to past events that can't be recreated. Think old newspaper articles, government reports, or personal diaries. The downside? You can't control the quality or completeness of the data.
Durkheim famously used official suicide statistics to develop his theory about social integration, showing how secondary data can support groundbreaking research. However, Giddens warned that secondary data gets interpreted through different theoretical lenses, potentially affecting objectivity.
Reality Check: Secondary sources are cost-effective and provide historical insight, but you're stuck with whatever data exists - gaps and biases included.
