Advantages and disadvantages of secondary data collection nowadays


1. The first advantage of using secondary data (SD) has always been the saving of time (Ghauri, 2005). Not enough with this, in the so called Internet Era, this fact is more than evident. In the past, secondary data collection used to require many hours of tracking on the long libraries corridors. New technology has revolutionized this world. The process has been simplified. Precise information may be obtained via search engines. All worth library has digitized its collection so that students and researchers may perform more advance searches.

2. Accessibility. In the past, SD was often confined to libraries or particular institutions. Top of that, not always general public gained access. Internet has especially been revolutionary in this sense. Having a internet connection is frequently the only requirement to access. A simple click is sometimes more than enough to obtain vast amount of information. The problem, nevertheless, is now being able to see whether the data is valid.

3. Strongly connected to the previous advantages is the saving of money (Ghauri, 2005). In general, it is much less expensive than other ways of collecting data. One may analyzed larger data sets like those collected by government surveys with no additional cost.

4. Feasibility of both longitudinal and international comparative studies. Continuous or regular surveys such as government censuses or official registers are especially good for such research purposes. The fact of being performed on a regular or continuous basis allow researchers to analyze the evolution of, to give an example, per capita income in Poland from 2000 to 2012. Something similar occurs when comparing different countries. Although important difference between countries may exist, the truth is that censuses and other government studies tend to unify criteria all over the world or, at least, within certain geographical areas, such as European Union, or among certain international organizations members, such as OECD. Another example are the studies carry out by international networks that aims to collect information world-widely following the same criteria. The World Values Survey is a good example. It is a source of empirical data on attitudes covering a majority of the world´s population (nearly 90%) It is carried out by a worldwide network of social scientist who, since 1981, have conducted representative national surveys in almost 100 countries. Aiming such data for international or longitudinal studies via primary data collection is truly difficult and often miss the rigor that diverse social contexts comparisons require.

5. Generating new insights from previous analyses (Fàbregues, 2013). Reanalyzing data can also lead to unexpected new discoveries. Returning to the previous example, the World Values Survey Association usually publish the so called World Values Survey Books. They are a collection of publications based on data from the World Values Surveys. Since the database used may be accessible for outsider, you can analyze the data and come up with new relevant conclusions or simply verify and confirm previous results.


1. Inappropriateness of the data. Data collected by oneself (primary data) is collected with a concrete idea in mind. Usually to answer a research question or just meet certain objectives.  In this sense, secondary data sources may provide you with vast amount of information, but quantity is not synonymous of appropriateness. This is simply because it has been collected to answer a different research question or objectives. (Denscombe, 2007). The inappropriateness may be, for instance, because of the data was collected many years ago, the information refers to a entire country when one aims to study a specific region, or the opposite, one aims to study an entire country but the information is given in a region wide. There are two possible ways to be taken when SD is not appropriate: 1) answering your research question partially with the subsequent lack of validity; 2) you need to find an alternative technique of data collection, such as survey or interviews.

2. Lack of control over data quality (Saunders, 2009). Government and other official institutions are often a guarantee of quality data, but it is not always the case. For this reason, quality issues must be verify as outlined in this post.

Any other advantage or disadvantage up? Would you like to add something else?

    1 the secondary research is fundamentally design for a purpose like what is the different among these hypothesis. therefore, the objective or the aim to design the research might be different because primary design for an objective. The objective is not specific for our proposal or anything else.
    2 there is less understanding of the process or studies in detail because we are not involved into the research and we are not the researchers
    3 problem identification and definition
    4 some informations might be missing through the final report but it is useful for us, the final report only pick the useful informations for their purpose so the other informations that they have been collected might be abandoned and that informations might be useful for us to use.
