TIPS FOR COLLECTING, REVIEWING, AND ANALYZING SECONDARY DATA WHAT TYPES OF DATA AND/OR INFORMATION ARE NEEDED? WHAT IS SECONDARY DATA REVIEW The specific types of information and/or data AND ANALYSIS? needed to conduct a secondary analysis will Secondary data analysis can be literally defined depend, obviously, on the focus of your study. as “second-hand” analysis. It is the analysis of For CARE purposes, secondary data analysis is data or information that was either gathered by usually conducted to gain a more in-depth someone else (e.g., researchers, institutions, understanding of the causes of poverty in the other NGOs, etc.) or for some other purpose than various countries and/or regions where CARE the one currently being considered, or often a works. Secondary data review and analysis combination of the two (Cnossen 1997). involves collecting information, statistics, and other relevant data at various levels of If secondary research and data analysis is aggregation in order to conduct a situational undertaken with care and diligence, it can analysis of the area (see Data & Indicator List in provide a cost-effective way of gaining a broad Appendix 1; refer to the LRSP Guidelines, understanding of research questions.

That is, data that is broken research projects. down in the following ways: gender, age, ethnicity, location, etc.. Scholarly Journals: Scholarly journals generally contain reports of original research or Even when highly disaggregated; however, these experimentation written by experts in specific “raw” data points alone are often only static or fields. Articles in scholarly journals usually indirect measures of the situation or problems undergo a peer review where other experts in the that exist in countries and regions – partial or same field review the content of the article for imperfect reflections of reality (UNDP 1997).

Cross-analyzing data will also publications from which the information is help you understand not only what is happing in derived. a particular area but also WHY it is happening. Trade Journals: Trade journals contain articles that discuss practical information concerning SOURCES OF SECONDARY DATA various fields. These journals provide people in Official Statistics: Official statistics are these fields with information pertaining to that statistics collected by governments and their field or trade. various agencies, bureaus, and departments. These statistics can be useful to researchers Reference Books: Reference books provide because they are an easily obtainable and secondary source material. In many cases, comprehensive source of information that specific facts or a summary of a topic is all that usually covers long periods of time. is included. Handbooks, manuals, encyclopedias, and dictionaries are considered However, because official statistics are often reference books (University of Cincinnati “characterized by unreliability, data gaps, over- Library 1996; Pritchard and Scott 1996). aggregation, inaccuracies, mutual inconsistencies, and lack of timely reporting” (Gill 1993), it is important to critically analyze WHERE TO FIND SECONDARY DATA official statistics for accuracy and validity.
