Questions to Ask Yourself When Looking for Data Sources

  • Who? Who might be interested in and able to collect the data you would like to find? That is, who might have an interest in the subject matter as well as the material support and expertise to conduct the data collection? Who might be required to make it publicly available? Who might be willing to share it voluntarily?
    • Which of these data collectors do you think will provide you the data that you need at no cost?
      • Government agencies 
      • Inter-governmental organizations 
      • Non-governmental organizations/non-profit organizations
      • Academic researchers
      • Think tanks/policy institutes
      • Community organizations​
      • Private companies
  • Who? Part two: Do you need nationally representative samples, or would smaller studies help you answer your question? Are you looking for data on certain segments of the population? 
  • When? Are you looking for current or historical data? Historical data from the same organization might be stored in a different database or data repository than current data. Older data and statistics might be only available in print form. 
  • Where? At what geographic level are you interested in studying - neighborhood, city, county, state, region, country, continent, world? What organizations or individuals might collect and share data at that geographic level?

Open Data Portals

What are open data portals? 

Some government entities make their data available to the public using open data portals. 

How to find open data portal

  • You can search for these in your favorite internet search engine - try searching for the name of the place and "open data" or "open data portal". 
  • Use the Global Open Data Index to find and evaluate how usable and transparent the data portal might be.   
  • claims to be the most comprehensive list of open data portals in the world. It is curated by a group of leading open data experts from around the world - including representatives from local, regional and national governments, international organisations such as the World Bank, and numerous NGOs.

Barriers to open data portals

Open Knowledge International notes three major environmental constraints that contribute to a lack of openness in government data sharing:

"1. Lack of capacity of government to maintain infrastructure and websites; incomplete and inaccessible published official information.
2. Limited open data knowledge from the respective government officials.
3. Limited capacity and open data knowledge of CSOs to take advantage or to ask for open data."
