What is the definition of secondary data in crime analysis?

The definition of secondary data in crime analysis refers to data that has been previously collected for a purpose other than the current research or analysis being conducted. This data is often stored electronically and may come from various sources such as government reports, historical crime statistics, or previous studies. By utilizing secondary data, analysts can leverage existing information to gain insights without the need for original data collection, which can be time-consuming and resource-intensive.

In the context of crime analysis, secondary data can include crime reports, census data, or records from law enforcement agencies. This enables analysts to identify trends, patterns, and correlations that inform policy decisions and crime prevention strategies.

In contrast, the other options do not correctly define secondary data. Collecting data for personal projects does not imply any specific purpose related to analysis, new data collected for immediate analysis refers to primary data, while suggesting that secondary data is only derived from social media platforms limits the broader scope of valuable existing datasets.
