What is secondary data? Definition and meaning.
Secondary data is the data that have been already collected for another purpose but has some relevance to your current research needs.
In other words, it has already been collected in the past by someone else, not you. And now, you can use the data.
Secondary data is second-hand information. It is not used for the first time. That is why it is called secondary.
Typically, secondary data is found in resources like the Internet, libraries, or reports.
Web information, business reports, mass media products, encyclopedias, and government statistics are among the most popular examples of secondary data.
Advantages And Disadvantages Of Secondary Data

The secondary data sources are very easy to access. The Internet has changed the way secondary research works. Nowadays, you have so much information available just by clicking with the mouse.
- Low cost or free
The majority of secondary sources are absolutely free for use or at very low costs. It saves not only your money but your efforts. In comparison with primary research where you have to design and conduct a whole primary study process from the beginning, secondary research allows you to gather data without having to put any money on the table. (see more on our post: primary vs secondary data)
As the above advantage suggests, you can perform secondary research in no time. Sometimes it is a matter of a few Google searches to find a source of data.
- Allow you to generate new insights from previous analysis
Reanalyzing old data can bring unexpected new understandings and points of view or even new relevant conclusions.
- Longitudinal analysis
Secondary data allows you to perform a longitudinal analysis which means the studies are performed spanning over a large period of time. This can help you to determine different trends. In addition, you can find secondary data from many years back up to a couple of hours ago. It allows you to compare data over time.
- Anyone can collect the data
Secondary data research can be performed by people that aren’t familiar with the different data collection methods. Practically, anyone can collect it.
- A huge amount of secondary data with a wide variety of sources
It is the richest type of data available to you in a wide variety of sources and topics.
- Might be not specific to your needs
Secondary data is not specific to the researcher’s needs due to the fact that it was collected in the past for another reason. That is why the secondary data might be unreliable for your current needs. Secondary data sources can give you a huge amount of information, but quantity does not always mean appropriateness.
- You have no control over data quality
The secondary data might lack quality. The source of the information may be questionable, especially when you gather the data via the Internet. As you relying on secondary data for your data-driven decision-making, you must evaluate the reliability of the information by finding out how the information was collected and analyzed.
As the secondary data is collected by someone else than you, typically the data is biased in favor of the person who gathered it. This might not cover your requirements as a researcher or marketer.
- Not timely
Secondary data is collected in the past which means it might be out-of-date. This issue can be crucial in many different situations.
- You are not the owner of the information
Generally, secondary data is not collected specifically for your company. Instead, it is available to many companies and people either for free or for a little fee. So, this is not exactly a “competitive advantage” for you. Your current and potential competitors also have access to the data.
Types Of Secondary Data
There are two types of secondary data, based on the data source:
- Internal sources of data: information gathered within the researcher’s company or organization (examples – a database with customer details, sales reports, marketing analysis, your emails, your social media profiles, etc).
- External sources of data: the data collected outside the organization (i.e. government statistics, mass media channels, newspapers, etc.)
Also, secondary data can be 2 types depending on the research strands:
- Quantitative data – data that can be expressed as a number or can be quantified. Examples – the weight and height of a person, the number of working hours, the volume of sales per month, etc. Quantitative data are easily amenable to statistical manipulation.
- Qualitative data – the information that can’t be expressed as a number and can’t be measured. Qualitative data consist of words, pictures, observations, and symbols, not numbers. It is about qualities. Examples – colors of the eyes (brown, blue, green), your socioeconomic status, customer satisfaction, and etc.
